Mr.
Chairman and Members of the Committee:
I
am pleased to be here today to discuss our analysis
of the information security controls over unclassified
systems of the Department of Commerce (Commerce). Dramatic
increases in computer interconnectivity, especially
in the use of the Internet, are revolutionizing the
way our government, our nation, and much of the world
communicate and conduct business, bringing vast amounts
of information and myriad resources and activities literally
at our fingertips. However, along with the enormous
benefits it brings, this widespread interconnectivity
poses significant risks to our computer systems, and
more important, to the critical operations and infrastructures
they support.
As
with other organizations, Commerce relies extensively
on computerized systems and electronic data to support
its mission. Moreover, Commerce generates and disseminates
some of the nation's most important economic information
that is of paramount interest to U.S. businesses, policymakers,
and researchers. Accordingly, the security of its systems
and data is essential to avoiding disruption in critical
operations, data tampering, fraud, and inappropriate
disclosure of sensitive information. Further, there
has be a dramatic rise in the number and sophistication
of cyberattacks on federal information systems. My testimony
today specifically focuses on the effectiveness of Commerce's
(1) logical access controls and other information system
controls over its computerized data,
(2) incident detection and response capabilities,and (3) information security
management program and related procedures. We
reviewed Commerce's information security controls and
currently have a draft report at Commerce for comment.
At
the seven Commerce organizations we reviewed,
significant and pervasive computer security weaknesses
exist that place sensitive Commerce systems
at serious risk. Using readily available software and
common techniques, we demonstrated the ability to penetrate
sensitive Commerce systems from both inside Commerce
and remotely, such as through the Internet. Individuals,
both within and outside Commerce, could gain unauthorized
access to these systems and read, copy, modify, and
delete sensitive economic, financial, personnel, and
confidential business data. Moreover, intruders could
disrupt the operations of systems that are critical
to the mission of the department. Additionally, unauthorized
access to sensitive systems may not be detected in time
to prevent or minimize damage. The underlying cause
for the numerous weaknesses we identified was the lack
of an effective program to manage information security.
We
identified vulnerabilities in four key areas in the
bureaus we reviewed:
·
First, controls intended
to protect information systems and critical data from
unauthorized access are ineffectively implemented, leaving
sensitive systems highly susceptible to intrusions or
disruptions. Specifically,
-
Systems were either not
configured to require passwords-including powerful systems
administrator accounts-or, if passwords were required,
they were relatively easy to guess, such as the word
"password" or commonly known default passwords supplied
by vendors. Further, (1) a significant number of passwords
never expired, (2) individuals had unlimited attempts
to guess passwords, and (3) unencrypted passwords, including
those having powerful system administrator functions,
could be widely viewed. Commerce bureaus also granted
excessive system administration privileges to employees
who did not require them, including 20 individuals who
had powerful system privileges that should be used only
in exceptional circumstances, such as recovery from
a power failure.
-
The configuration of Commerce
operating systems exposed excessive amounts of system
information to anyone, without the need for authentication,
allowing potential attackers to collect systems information
that could be used to circumvent security controls and
gain unauthorized access. In addition, Commerce did
not properly configure operating systems to ensure that
they would be available to support bureau missions or
prevent the corruption of important data. For example,
in a large computer system affecting several bureaus,
thousands of important programs had not been assigned
unique names, which could result in unintended programs
being inadvertently run, potentially corrupting data
or disrupting system operations. In this same system,
because critical parts of the operating system were
shared by the test and production systems, changes in
either system could corrupt or shut down the other system.
Additionally, unnecessary and poorly configured system
functions existed on important computer systems in all
bureaus we reviewed, allowing us to gain access from
the Internet.
-
None of the Commerce bureaus
reviewed had effective external and internal network
security controls. Our testing demonstrated that individuals,
both within and outside Commerce, could compromise external
and internal security controls to gain extensive unauthorized
access to the department's networks and systems. We
obtained such access as a result of weakly configured
external control devices, poorly controlled dial-up
modems, and ineffective internal network controls.
·
Second, we found other control
weaknesses, including inadequate
(1) segregation of computer duties of the staff to mitigate
the risk of errors or fraud, (2) control of software
changes to ensure that only authorized and fully tested software is placed in operation,
and
(3) development of comprehensive and completed recovery
plans to ensure the continuity of service in the event
of a service disruption.
·
Third, Commerce is not adequately
(1) preventing intrusions before they occur, (2) detecting
intrusions as they occur, (3) responding to successful
intrusions, or (4) reporting intrusions to staff and
management. Thus, there is little assurance that unauthorized
attempts to access sensitive information will be identified
and appropriate actions taken in time to prevent or
minimize damage. For example, Commerce has not instituted
key measures to prevent incidents, such as acquiring
software updates to correct known vulnerabilities. During
our testing we discovered 20 systems with known vulnerabilities
for which patches were available but not installed.
As a result of ineffective detection capabilities, the
tested bureaus were generally unable to detect our extensive
intrusion activities (only two of the bureaus had installed
intrusion detection systems). Also, only one of the
bureaus has established incident response procedures;
in two instances when our activity was detected, Commerce
employees who detected our testing inappropriately responded
by launching attacks against our systems. Moreover,
these two incidents were never reported to the bureaus'
security officer.
·
Fourth, and most important,
Commerce does not have an effective departmentwide information
security management program to ensure that sensitive
data and critical operations are adequately addressed
and that appropriate security controls are in place
to protect them. Key issues include
-
Lack
of a strong centralized management function to oversee
and coordinate departmentwide security-related activities.
At the time of our review, Commerce's CIO,
who had broad responsibility for information security
throughout the department, said that he believed that
he did not have sufficient resources or the authority
to implement this program. This lack of a centralized
approach to managing security is particularly risky
considering the widespread interconnectivity of Commerce's
systems.
-
Widespread
lack of risk assessment. Commerce is doing
little to understand and manage risks to its systems.
For example, as of March 2001, of the bureaus' 94 sensitive
systems we reviewed, 91 did not have documented risk
assessments, 87 had no security plans, and none were
authorized[6]
for processing by Commerce management.
Consequently, most of the bureaus' systems are being
operated without considering the risks associated with
their immediate environment. Moreover, several bureau
officials acknowledged that they had not considered
how vulnerabilities in systems that interconnected with
theirs could undermine the security of their own systems.
-
Significantly
outdated and incomplete information security policies.
Commerce's information security policy, developed
in 1993 and partially revised in 1995, does not reflect
current federal requirements for managing computer security
on a continuing basis, developing security plans, authorizing
processing, providing security awareness training, or
performing system reviews. Moreover, Commerce has not
updated its policy to reflect the risks of Internet
use and has no policies establishing baseline security
requirements for all systems. For example, there is
no policy specifying required attributes for passwords,
such as minimum length and the inclusion of special
characters.
-
Inadequately
promoted security awareness and training.
Although each of the seven bureaus reviewed have informal
programs in place, none have documented computer security
training procedures that meet federal requirements for
ensuring that security risks and responsibilities are
understood by all managers, users, and system administrators.
-
Lack
of an ongoing program to test and evaluate security
controls. No oversight reviews of the Commerce
bureaus' systems have been performed by the staff of
Commerce's information security program. Furthermore,
the bureaus we reviewed do not monitor the effectiveness
of their information security. Only one of the bureaus
has performed isolated tests of its systems.
The
lack of an effective information security program is
exacerbated by Commerce's highly interconnected computing
environment in which the vulnerabilities of individual
systems affect the security of systems in the entire
department. A compromise in a single poorly secured
system can undermine the security of the multiple systems
that connect to it.
In
the last 2 years, the Commerce CIO introduced several
initiatives to improve the security posture of the department,
including a summary evaluation of information security
based on bureau self-assessments and related follow-up.
Also, in June 2001, after our fieldwork was completed,
the Secretary of Commerce approved a high-level Commerce
information technology (IT) restructuring plan. The
acting CIO stated that Commerce is developing a more
detailedrestructuring implementationplan plan. Regardless
of its particular approach, we have made recommendations
that Commerce needs to implement in order to address
the weaknesses in its information security controls.
In
the rest of my statement today, I will discuss in more
detail the results of our review of Commerce's information
security controls; these results are included in our
draft report, which also contains more detailed recommendations.
Information
security is an important consideration for any organization
that depends on information systems to carry out its
mission. The dramatic expansion in computer interconnectivity
and the exponential increase in the use of the Internet
are changing the way our government, the nation, and
much of the world communicate and conduct business.
However, risks are significant, and they are growing.
The number of computer security incidents reported to
the CERT Coordination Centerâ
(CERT/CC)
rose from 9,859 in 1999 to 21,756 in 2000. For the first
6 months of 2001, the number reported was 15,476.
As
the number of individuals with computer skills has increased,
more intrusion or "hacking" tools have become readily
available and relatively easy to use. A potential hacker
can literally download tools from the Internet and "point
and click" to start a hack. According to a recent
National Institute of Standards and Technology (NIST) publication,
hackers post 30 to 40 new tools to hacking sites on
the Internet every month. The successful cyber attacks
against such well-known U.S. e-commerce Internet sites
as eBay, Amazon.com, and CNN.com by a 15-year old "script
kiddie"
in February 2000 illustrate the risks. Without proper
safeguards, these developments make it easier for individuals
and groups with malicious intentions to gain unauthorized
access to systems and use their access to obtain sensitive
information, commit fraud, disrupt operations, or launch
attacks against other organizations' sites.
|
Federal
Systems Are At Risk
|
Government
officials are increasingly concerned about federal computer
systems, which process, store, and transmit enormous
amounts of sensitive data and are indispensable to many
federal operations. The federal government's systems
are riddled with weaknesses that continue to put critical
operations at risk. Since October 1998, the Federal
Computer Incident Response Center's (FedCIRC)
records have shown an increasing trend in the number
of attacks targeting government systems. In 1998 FedCIRC
documented 376 incidents affecting 2,732 federal civilian systems and 86 military systems. In
2000, the number of attacks rose to 586 incidents affecting
575,568 federal systems and 148 of their military counterparts.
Moreover, according to FedCIRC, these numbers reflect
only reported incidents, which it estimates do not include
as many as 80 percent of actual security incidents.
According to FedCIRC, 155 of the incidents reported
in 2000, which occurred at 32 agencies, resulted in
what is known as a "root compromise."
For at least five of the root compromises, government
officials were able to verify that access to sensitive
information had been obtained.
How
well federal agencies are addressing these risks is
a topic of increasing interest in the executive and
legislative branches. In January 2000, President Clinton
issued a National
Plan for Information Systems Protection
and designated computer security and critical infrastructure
protection a priority management objective in his fiscal
year 2001 budget. The new administration, federal agencies,
and private industry have collaboratively begun to prepare
a new version of the national plan that will outline
an integrated approach to computer security and critical
infrastructure protection.
The
Congress, too, is increasingly interested in computer
security, as evidenced by important hearings held during
1999, 2000, and 2001 on ways to strengthen information
security practices throughout the federal government
and on progress at specific agencies in addressing known
vulnerabilities. Furthermore, in October 2000, the Congress
included government information security reform provisions
in the fiscal year 2001 National Defense Authorization
Act. These provisions seek to ensure proper management
and security for federal information systems by calling
for agencies to adopt risk management practices that
are consistent with those summarized in our 1998 Executive
Guide.
The provisions also require annual agency program reviews
and Inspector General (IG) evaluations that must be
reported to the Office of Management and Budget (OMB)
as part of the budget process.
The
federal CIO Council and others have also initiated several
projects that are intended to promote and support security
improvements to federal information systems. Over the
past year, the CIO Council, working with NIST, OMB,
and us, developed the Federal Information Technology
Security Assessment Framework.
The framework provides agencies with a self-assessment
methodology to determine the current status of their
security programs and to establish targets for improvement.
OMB has instructed agencies to use the framework to
fulfill their annual assessment and reporting obligations.
Since
1996, our analyses of information security at major
federal agencies have shown that systems are not being
adequately protected. Our previous reports, and those
of agency IGs, describe persistent computer security
weaknesses that place a variety of critical federal
operations at risk of inappropriate disclosures, fraud,
and disruption.
This body of audit evidence has led us, since 1997,
to designate computer security as a governmentwide high-risk
area.
Our
most recent summary analysis of federal information
systems found that significant computer security weaknesses
had been identified in 24 of the largest federal agencies,
including Commerce.
During December 2000 and January 2001, Commerce's IG
also reported significant computer security weaknesses
in several of the department's bureaus and, in February
2001, reported information security as a material weakness
affecting the department's ability to produce accurate
data for financial statements.
The report stated that there were weaknesses in several
areas, including entitywide security management, access
controls, software change controls, segregation of duties,
and service continuity planning. Moreover, a recent
IG assessment of the department's information security
program found fundamental weaknesses in the areas of
policy and oversight.
Also, the IG designated information security as one
of the top ten management challenges for the department.
Commerce's
missions are among the most diverse of the federal government's
cabinet departments, covering a wide range of responsibilities
that include observing and managing natural resources
and the environment; promoting commerce, regional development,
and scientific research; and collecting, analyzing,
and disseminating statistical information. Commerce
employs about 40,000 people in fourteen operating bureaus
with numerous offices in the U.S. and overseas, each
pursuing disparate programs and activities.
|
Commerce
Missions
Are Diverse
|
IT
is a critical tool for Commerce to support these missions.
The department spends significant resources-reportedly
over $1.5 billion in fiscal year 2000-on IT systems
and services. As a percentage of total agency expenditures
on IT, Commerce ranks among the top agencies in the
federal government, with 17 percent of its $9-billion
fiscal year 2000 budget reported as spent on IT.
A
primary mission of Commerce is to promote job creation
and improved living standards for all Americans by furthering
U.S. economic growth, and the seven bureaus we reviewed
support this mission through a wide array of programs
and services. Commerce uses IT to generate and disseminate
some of the nation's most important economic information.
The International Trade Administration (ITA) promotes
the export of U.S. goods and services-which amounted
to approximately $1.1 trillion in fiscal year 2000.
Millions of American jobs depend on exports, and with
96 percent of the world's consumers living outside U.S.
borders, international trade is increasingly important
to supporting this mission. The Economics and Statistics
Administration (ESA) develops, prepares, analyzes, and
disseminates important indicators of the U.S. that present
basic information on such key issues as economic growth,
regional development, and the U.S. role in the world
economy. This information is of paramount interest to
researchers, business, and policymakers.
The
Bureau of Export Administration (BXA), whose efforts
supported sales of approximately $4.2 billion in fiscal
year 1999, assists in stimulating the growth of U.S.
exports while protecting national security interests
by helping to stop the proliferation of weapons of mass
destruction. Sensitive data such as that relating to
national security, nuclear proliferation, missile technology,
and chemical and biological warfare reside in this bureau's
systems.
Commerce's
ability to fulfill its mission depends on the confidentiality,
integrity, and availability of this sensitive information.
For example, export data residing in the BXA systems
reflect technologies that have both civil and military
applications; the misuse, modification, or deletion
of these data could threaten our national security or
public safety and affect foreign policy. Much of these
data are also business proprietary. If it were compromised,
the business could not only lose its market share, but
dangerous technologies might end up in the hands of
renegade nations who threaten our national security
or that of other nations.
|
Commerce's
IT
Infrastructure Is
Decentralized
|
Commerce's
IT infrastructure is decentralized. Although the Commerce
IT Review Board approves major acquisitions, most bureaus
have their own IT budgets and act independently to acquire,
develop, operate, and maintain their own infrastructure.
For example, Commerce has 14 different data centers,
diverse hardware platforms and software environments,
and 20 independently managed e-mail systems. The bureaus
also develop and control their own individual networks
to serve their specific needs. These networks vary greatly
in size and complexity. For example, one bureau has
as many as 155 local area networks and 3,000 users spread
over 50 states and 80 countries. Some of these networks
are owned, operated, and managed by individual programs
within the same bureau.
Because
Commerce does not have a single, departmentwide common
network infrastructure to facilitate data communications
across the department, the bureaus have established
their own access paths to the Internet, which they rely
on to communicate with one another. In April 2001, the
department awarded a contract for a $4 million project
to consolidate the individual bureaus' local area networks
within its headquarters building onto a common network
infrastructure. However, until this project is completed,
each of the bureaus is expected to continue to configure,
operate, and maintain its own unique networks.
|
Improvements
to
Information Security
Have Been Initiated
|
Recognizing
the importance of its data and operations, in September
1993 Commerce established departmentwide information
security policies that defined and assigned a full set
of security responsibilities, ranging from the department
level down to individual system owners and users within
the bureaus. Since 1998, the Commerce CIO position has
been responsible for developing and implementing the
department's information security program. An information
security manager, under the direction of the CIO's Office
of Information Policy, Planning, and Review, is tasked
with carrying out the responsibilities of the program.
The CIO's responsibilities for the security of classified
systems has been delegated to the Office of Security.
In
the last 2 years, the CIO introduced several initiatives
that are essential to improving the security posture
of the department. After a 1999 contracted evaluation
of the bureaus' security plans determined that 43 percent
of Commerce's most critical assets did not have current
information system security plans, the CIO issued a
memorandum calling for the bureaus to prepare security
plans that comply with federal regulations. Also, in
May 2000, the Office of the CIO performed a summary
evaluation of the status of all the bureaus' information
security based on the bureaus' own self-assessments.
The results determined that overall information security
program compliance was minimal, that no formal information
security awareness and training programs were provided
by the bureaus, and that incident response capabilities
were either absent or informal. The Commerce IG indicated
that subsequent meetings between the Office of the CIO
and the bureaus led to improvements. The Office of the
CIO plans to conduct another evaluation this year and,
based on a comparison with last year's results, measure
the bureaus' success in strengthening their security
postures.
Finally,
for the past year, the CIO attempted to restructure
the department's IT management to increase his span
of control over information security within the bureaus
by enforcing his oversight authority and involvement
in budgeting for IT resources. However, this initiative
was not approved before the CIO's resignation in 2001.
In June 2001, after our fieldwork was completed, the
Secretary of Commerce approved a high-level Commerce
IT restructuring plan. The acting CIO stated that a
task force is developing a more detailed implementation
plan.
|
Logical
Access Controls Were Inadequate
|
A
basic
management objective for any organization
is the protection of its information systems and critical
data from unauthorized access. Organizations accomplish
this objective by establishing controls that limit access
to only authorized users, effectively configuring their
operating systems, and securely implementing networks.
However, our tests identified weaknesses in each of
these control areas in all of the Commerce bureaus we
reviewed. We demonstrated that individuals, both external
and internal to Commerce, could compromise security
controls to gain extensive unauthorized access to Commerce
networks and systems. These weaknesses place the bureaus'
information systems at risk of unauthorized access,
which could lead to the improper
disclosure, modification, or deletion
of sensitive information and
the disruption of critical operations. As previously
noted, because of the sensitivity of specific
weaknesses, we plan to issue a report designated for
"Limited Official Use," which describes in
more detail each of the computer security weaknesses
identified and offers specific recommendations for correcting
them.
|
System
Access
Controls Were Weak
|
Effective
system access controls provide mechanisms that require
users to identify themselves and authenticate
their identity, limit the use of system administrator
capabilities to authorized individuals, and protect
sensitive system and data files. As with many organizations,
passwords are Commerce's primary means of authenticating
user identity. Because system administrator capabilities
provide the ability to read, modify, or delete any data
or files on the system and modify the operating system
to create access paths into the system, such capabilities
should be limited to the minimum access levels necessary
for systems personnel to perform their duties. Also,
information can be protected by using controls that
limit an individual's ability to read, modify, or delete
information stored in sensitive system files.
User
ID and Password Management
Controls Were Not Effective
One
of the primary methods to prevent unauthorized access
to information system resources is through effective
management of user IDs and passwords. To accomplish
this objective, organizations should establish controls
that include requirements to ensure that well-chosen
passwords are required for user authentication, passwords
are changed periodically, the number of invalid password
attempts is limited to preclude password guessing, and
the confidentiality of passwords is maintained and protected.
All
Commerce bureaus reviewed were not effectively managing
user IDs and passwords to sufficiently reduce the risk
that intruders
could gain unauthorized access to its information
systems to (1) change system access and other rules,
(2) potentially read,
modify, and delete or redirect network traffic, and
(3) read, modify, and delete sensitive information.
Specifically, systems
were either not configured to require passwords or,
if passwords were required, they were relatively easy
to guess. For example,
·
powerful system administrator
accounts did not require passwords, allowing anyone
who could connect to certain systems through the network
to log on as a system administrator without having to
use a password,
·
systems allowed users to
change their passwords to a blank password, completely
circumventing the password control function,
·
passwords were easily guessed
words, such as "password,"
·
passwords were the same
as the user's ID, and
·
commonly known default passwords
set by vendors when systems were originally shipped
had never been changed.
Although
frequent password changes reduce the risk of continued
unauthorized use of a compromised password, systems
in four of the bureaus reviewed had a significant number
of passwords that never required changing or did not
have to be changed for 273 years. Also, systems in six
of the seven bureaus did not limit the number of times
an individual could try to log on to a user ID. Unlimited
attempts allow intruders to keep trying passwords until
a correct password is discovered.
Further,
all Commerce bureaus reviewed did not adequately protect
the passwords of their system users through measures
such as encryption, as illustrated by the following
examples:
·
User
passwords were stored in readable text files that could
be viewed by all users on one bureau's systems.
·
Files that store user passwords
were not protected from being copied by intruders, who
could then take the copied password files and decrypt
user passwords. The decrypted passwords could then be
used to gain unauthorized access to systems by intruders
masquerading as legitimate users.
·
Over 150 users of one system
could read the unencrypted password of a powerful system
administrator's account.
Control
of System Administration
Functions Was Not Adequate
System
administrators perform important functions in support
of the operations of computer systems. These functions
include defining security controls, granting users access
privileges, changing operating system configurations,
and monitoring system activity. In order to perform
these functions, system administrators have powerful
privileges that enable them to manipulate operating
system and security controls. Privileges to perform
these system administration functions should be granted
only to employees who require such privileges to perform
their responsibilities and who are specifically trained
to understand and exercise those privileges. Moreover,
the level of privilege granted to employees should not
exceed the level required for them to perform their
assigned duties. Finally, systems should provide accountability
for the actions of system administrators on the systems.
However,
Commerce bureaus granted the use of excessive system
administration privileges to employees who did not require
such privileges
to perform their responsibilities and
who were not trained to exercise them. For example,
a very powerful system administration privilege that
should be used only in exceptional circumstances, such
as recovery from a power failure, was granted to 20
individuals.
These 20 individuals had the ability to access all of
the information stored on the system, change important
system configurations that could affect the system's
reliability, and run any program on the computer. Further,
Commerce management also acknowledged that not all staff
with access to this administrative privilege had been
adequately trained.
On
other important systems in all seven bureaus, system
administrators were sharing user IDs
and passwords so that systems could not provide an audit
trail of access by system administrators, thereby limiting
accountability. By not effectively controlling the number
of staff who exercise system administrator privileges,
restricting the level of such privileges granted to
those required to perform assigned duties, or ensuring
that only well-trained staff have these privileges,
Commerce is increasing the
risk that unauthorized activity could occur and the
security of sensitive information be compromised.
Access
to Critical Systems
and Sensitive Data Files
Was Not Adequately Restricted
Access
privileges to individual critical systems and sensitive
data files should be restricted to authorized users.
Not only does this restriction protect files that may
contain sensitive information from unauthorized access,
but it also provides another layer of protection against
intruders who may have successfully penetrated one system
from significantly extending their unauthorized access
and activities to other systems. Examples of access
privileges
are the capabilities to read, modify,
or delete a file. Privileges can be granted to individual
users, to groups of users, or to everyone who accesses
the system.
Six
of the seven bureaus' systems were not
configured to appropriately restrict access to sensitive
system and/or data files. For example, critical system
files could be modified by all users to allow them to
bypass security controls. Also, excessive access privileges
to sensitive data files such as export license applications
were granted. Systems configured with excessive
file access privileges are extremely vulnerable
to compromise because such configurations could enable
an intruder to read, modify, or delete sensitive system
and data files, or to disrupt the availability and integrity
of the system.
|
Operating
Systems
Were Ineffectively
Secured
|
Operating
system controls are essential to ensure that the computer
systems and security controls function as intended.
Operating systems are relied on by all the software
and hardware in a computer system. Additionally, all
users depend on the proper operation of the operating
system to provide a consistent and reliable processing
environment, which is essential to the availability
and reliability of the information stored and processed
by the system.
Operating
system controls should limit the extent of information
that systems provide to facilitate system interconnectivity.
Operating systems should be configured to help ensure
that systems are available and that information stored
and processed is not corrupted. Controls should also
limit the functions
of the computer system to prevent insecure system configurations
or the existence of functions not needed to support
the operations of the system. If functions are not properly
controlled, they can be used by intruders to circumvent
security controls.
Excessive
System
Information Was Exposed
To
facilitate interconnectivity between computer systems,
operating systems are configured to provide descriptive
and technical information, such as version numbers and
system names, to other computer systems and individuals
when connections are being established. At the same
time, however, systems should be configured to limit
the amount of information that is made available to
other systems and unidentified individuals because this
information can be misused by potential intruders to
learn the characteristics and vulnerabilities of that
system to assist in intrusions.
Systems
in all bureaus reviewed were not configured to control
excessive system information from exposure to potential
attackers. The configuration of Commerce systems provided
excessive amounts of information to anyone, including
external users, without the need for authentication.
Our testing demonstrated that potential attackers could
collect information about systems, such as computer
names, types of operating systems, functions, version
numbers, user information, and other information that
could be useful to circumvent security controls and
gain unauthorized access.
Operating
Systems Were
Poorly Configured
The
proper configuration of operating systems is important
to ensuring the reliable operation of computers and
the continuous availability and integrity
of
critical information. Operating systems should be configured
so that the security controls throughout the system
function effectively and the system can be depended
on to support the organization's mission.
Commerce
bureaus did not properly configure operating systems
to ensure that systems would be available to support
bureau missions or prevent the corruption of the information
relied on by management and the public. For example,
in a large computer system affecting several bureaus,
there were thousands of important programs that had
not been assigned unique names. In some instances, as
many as six different programs all shared the same name,
many of which were different versions of the same program.
Although typically the complexity of such a system may
require the installation of some programs that are identically
named and authorized programs must be able to bypass
security in order to operate, there were an excessive
number of such programs installed on this system, many
of which were capable of bypassing security controls.
Because
these different programs are identically named, unintended
programs could be inadvertently run, potentially resulting
in the corruption of data or disruption of system operations.
Also, because these powerful programs are duplicated,
there is an increased likelihood that they could be
misused to bypass security controls.
In
this same system, critical parts of the operating system
were shared by the test and production systems used
to process U.S. export information. Because critical
parts were shared, as changes are made in the test system,
these changes could also affect the production system.
Consequently, changes could be made in the test system
that would cause the production system to stop operating
normally and shut down. Changes in the test system could
also cause important Commerce data in the production
system to become corrupted. Commerce management acknowledged
that the isolation between these two systems needed
to be strengthened to mitigate these risks.
Systems
Had Unnecessary and
Poorly Configured Functions
Operating
system functions should be limited to support only the
capabilities needed by each specific computer system.
Moreover, these functions should be appropriately configured.
Unnecessary operating system functions can be used to
gain unauthorized access to a system and target that
system for a denial-of-service attack.
Poorly configured operating system functions can allow
individuals to bypass security controls and access sensitive
information without requiring proper identification
and authentication.
Unnecessary
and poorly configured system functions existed on important
computer systems in all the bureaus we reviewed.
For example, unnecessary functions allowed us to gain
access to a system from the Internet. Through such access
and other identified weaknesses, we were able to gain
system administration privileges on that
system and subsequently gain access to other systems
within other Commerce bureaus.
Also, poorly configured functions would
have allowed users to bypass security controls and gain
unrestricted access to all programs and data.
|
Network
Security
Was Ineffective
|
Networks
are a series of interconnected information technology
devices and software that allow groups of individuals
to share data, printers, communications systems, electronic
mail, and other resources. They provide the entry point
for access to electronic information assets and provide
users with access to the information technologies they
need to satisfy the organization's mission. Controls
should restrict access to networks from sources external
to the network. Controls should also limit the use of
systems from sources internal to the network to authorized
users for authorized purposes.
External
threats include individuals outside an organization
attempting to gain unauthorized access to an organization's
networks using the Internet, other networks, or dial-up
modems. Another form of external threat is flooding
a network with large volumes of access requests so that
the network is unable to respond to legitimate requests,
one type of denial-of-service attack. External threats
can be countered by implementing security controls on
the perimeters of the network, such as firewalls,
that limit user access and data interchange between
systems and users within the organization's network
and systems and users outside the network, especially
on the Internet. An example of perimeter defenses is
only allowing pre-approved computer systems from outside
the network to exchange certain types of data with computer
systems inside the network. External network controls
should guard the perimeter of the network from connections
with other systems and access by individuals who are
not authorized to connect with and use the network.
Internal
threats come from sources that are within an organization's
networks, such as a disgruntled employee with access
privileges who attempts to perform unauthorized activities.
Also, an intruder who has successfully penetrated a
network's perimeter defenses becomes an internal threat
when the intruder attempts to compromise other parts
of an organization's network security as a result of
gaining access to one system within the network. For
example, at Commerce, users of one bureau who have no
business need to access export license information on
another bureau's network should not have had network
connections to that system.
External
network security controls should prevent unauthorized
access from outside threats, but if those controls fail,
internal network security controls should also prevent
the intruder from gaining unauthorized access to other
computer systems within the network.
None
of the Commerce bureaus reviewed had effective external
and internal network security controls. Individuals,
both within and outside Commerce, could compromise external
and internal security controls to gain extensive unauthorized
access to Commerce networks and systems. Bureaus employed
a series of external
control
devices, such as firewalls, in some, but not all, of
the access paths to their networks. However, these controls
did not effectively prevent unauthorized access to Commerce
networks from the Internet or through poorly controlled
dial-up modems that bypass external controls. For example,
four
bureaus had not configured their firewalls to adequately
protect their information systems from intruders on
the Internet. Also, six dial-up modems were installed
so that anyone could connect to their network without
having to use a password, thereby circumventing the
security controls provided by existing firewalls.
Our
testing demonstrated that, once access was gained by
an unauthorized user on the Internet or through a dial-up
modem to one bureau's networks, that intruder could
circumvent ineffective internal network controls to
gain unauthorized access to other networks within Commerce.
Such weak internal network controls could allow an unauthorized
intruder or authorized user on one bureau's network
to change the configuration of other bureaus' network
controls so that the user could observe network traffic,
including passwords and sensitive information that Commerce
transmits in readable clear text, and disrupt network
operations.
The
external and internal security controls of the different
Commerce
bureau
networks did not provide a consistent level of security
in part because bureaus independently configured and
operated their networks as their own individual networks.
For example, four of the bureaus we reviewed had their
own independently controlled access points to the Internet.
Because
the different bureaus'
networks
are actually logically interconnected and perform as
one large interconnected network, the ineffective network
security
controls
of one bureau jeopardize the security of other bureaus'
networks. Weaknesses in the external and internal network
controls of the individual bureaus heighten the risk
that outside intruders with no prior knowledge of bureau
user IDs or passwords, as well as Commerce employees
with malicious intent, could exploit the other security
weaknesses in access and operating system controls discussed
above to misuse, improperly disclose, or destroy sensitive
information.
|
Other
Information
System Controls Were
Not Adequate
|
In
addition to logical access controls, other important
controls should be in place to ensure the confidentiality,
integrity, and reliability of an organization's data.
These information system controls include policies,
procedures, and techniques to provide appropriate segregation
of duties among computer personnel, prevent unauthorized
changes to application programs, and ensure the continuation
of computer processing operations in case of unexpected
interruption. The Commerce bureaus had weaknesses in
each of these areas that heightened the risks already
created by their lack of effective access controls.
|
Computer
Duties Were Not
Properly Segregated
|
A
fundamental technique for safeguarding programs and
data is to segregate the duties and responsibilities
of computer personnel to reduce the risk that errors
or fraud will occur and go undetected. OMB A-130, Appendix
III, requires that roles and responsibilities be divided
so that a single individual cannot subvert a critical
process. Once policies and job descriptions that support
the principles of segregation of duties have been established,
access controls can then be implemented to ensure that
employees perform only compatible functions.
None
of the seven bureaus in our review had specific policies
documented to identify and segregate incompatible duties,
and bureaus had assigned incompatible duties to staff.
For example, staff were performing incompatible computer
operations and security duties. In another instance,
the bureau's security officer had the dual role of also
being the bureau's network administrator. These two
functions are not compatible since the individual's
familiarity with system security could then allow him
or her to bypass security controls either to facilitate
performing administrative duties or for malicious purposes.
Furthermore,
none of the bureaus reviewed had implemented processes
and procedures to mitigate the increased risks of personnel
with incompatible duties. Specifically, none of the
bureaus had a monitoring process to ensure appropriate
segregation of duties, and management did not review
access activity. Until Commerce restricts individuals
from performing incompatible duties and implements compensating
access controls, such as supervision and review, Commerce's
sensitive information will face increased risks of improper
disclosure, inadvertent or deliberate misuse, and deletion,
all of which could occur without detection.
Software
Changes Were Not Adequately Controlled
|
Also
important for an organization's information security
is ensuring that only authorized and fully tested software
is placed in operation. To make certain that software
changes are needed, work as intended, and do not result
in the loss of data and program integrity, such changes
should be documented, authorized, tested, and independently
reviewed. Federal guidelines emphasize the importance
of establishing controls to monitor the installation
of and changes to software to ensure that software functions
as expected and that a historical record is maintained
of all changes.
We
have previously reported on Commerce's lack of policies
on software change controls.
Specific key controls not addressed were (1) operating
system software changes, monitoring, and access and
(2) controls over application software libraries including
access to code, movement of software programs, and inventories
of software. Moreover, implementation was delegated
to the individual bureaus, which had not established
written policies or procedures for managing software
changes.
Only
three of the seven bureaus we reviewed mentioned software
change controls in their system security plans, while
none of the bureaus had policies or procedures for controlling
the installation of software. Such policies are important
in order to ensure that software changes do not adversely
affect operations or the integrity of the data on the
system. Without proper software change controls, there
are risks that security features could be inadvertently
or deliberately omitted or rendered inoperable, processing
irregularities could occur, or malicious code could
be introduced.
|
Service
Continuity Planning Was Incomplete
|
Organizations
must take steps to ensure that they are adequately prepared
to cope with a loss of operational capability due to
earthquakes, fires, sabotage, or other disruptions.
An essential element in preparing for such catastrophes
is an up-to-date, detailed, and fully tested recovery
plan that covers all key computer operations. Such a
plan is critical for helping to ensure that information
system operations and data can be promptly restored
in the event of a service disruption. OMB Circular A-130,
Appendix III, requires that agency security plans assure
that there is an ability to restore service sufficient
to meet the minimal needs of users. Commerce policy
also requires a backup or alternate operations strategy.
The
Commerce bureaus we reviewed had not developed comprehensive
plans to ensure the continuity of service in the event
of a service disruption. Described below are examples
of service continuity weaknesses we identified at the
seven Commerce bureaus.
·
None of the seven bureaus
had completed recovery plans for all of their sensitive
systems.
·
Although one bureau had
developed two recovery plans, one for its data center
and another for its software development installation
center, the bureau did not have plans to cover disruptions
to the rest of its critical systems, including its local
area network.
·
Systems at six of the seven
bureaus did not have documented backup procedures.
·
One bureau stated that it
had an agreement with another Commerce bureau to back
it up in case of disruptions; however, this agreement
had not been documented.
·
One bureau stated in its
backup strategy that tapes used for system recovery
are neither stored off-site nor protected from destruction.
For example, backup for its network file servers is
kept in a file cabinet in a bureau official's supply
room, and backup tapes for a database and web server
are kept on the shelf above the server. In case of a
destructive event, the backups could be subject to the
same damage as the primary files.
·
Two bureaus had no backup
facilities for key network devices such as firewalls.
Until
each of the Commerce bureaus develops and fully tests
comprehensive recovery plans for all of its sensitive
systems, there is little assurance that in the event
of service interruptions, many functions of the organization
will not effectively cease and critical data will be
lost.
|
Poor
Incident Detection and Response Capabilities
Further Impair Security
|
As
our government becomes increasingly dependent on information
systems to support sensitive data and mission critical
operations, it is essential that agencies protect these
resources from misuse and disruption. An important component
of such protective efforts is the capability to promptly
identify and respond to incidents of attempted system
intrusions. Agencies can better protect their information
systems from intruders by developing formalized mechanisms
that integrate incident handling functions with the
rest of the organizational security infrastructure.
Through such mechanisms, agencies can address how to
(1) prevent intrusions before they occur, (2) detect
intrusions as they occur, (3) respond to successful
intrusions, and (4) report intrusions to staff and management.
Although
essential to protecting resources, Commerce bureau incident
handling capabilities are inadequate in preventing,
detecting, responding to, and reporting incidents. Because
the bureaus have not implemented comprehensive and consistent
incident handling capabilities, decision-making may
be haphazard when a suspected incident is detected,
thereby impairing responses and reporting. Thus, there
is little assurance that unauthorized attempts to access
sensitive information will be identified and appropriate
actions taken in time to prevent or minimize damage.
Until adequate incident detection and response capabilities
are established, there is a greater risk that intruders
could be successful in copying, modifying, or deleting
sensitive data and disrupting essential operations.
|
Incident
Handling Mechanisms Have Not Been Established
or Implemented
|
Accounting
for and analyzing computer security incidents are effective
ways for organizations to better understand threats
to their information systems. Such analyses can also
pinpoint vulnerabilities that need to be addressed so
that they will not be exploited again. OMB Circular
A-130,
Appendix III, requires agencies to establish formal
incident response mechanisms dedicated to evaluating
and responding to security incidents in a manner that
protects their own information and helps to protect
the information of others who might be affected by the
incident. These formal incident response mechanisms
should also share information concerning common vulnerabilities
and threats within the organization as well as with
other organizations. By establishing such mechanisms,
agencies help to ensure that they can more effectively
coordinate their activities when incidents occur.
Although
the Commerce CIO issued a July 1999 memorandum to all
bureau CIOs outlining how to prevent, detect, respond
to, and report incidents, the guidance has been inconsistently
implemented. Six
of the seven bureaus we reviewed have only ad hoc processes
and procedures for handling incidents. None have established
and implemented all of the requirements of the memo.
Furthermore, Commerce does not have a centralized function
to coordinate the handling of incidents on a
departmentwide basis.
|
Incidents
Could Be Prevented
|
Two
preventive measures for deterring system intrusions
are to install
(1) software updates to correct known vulnerabilities
and (2) messages warning intruders that their activities
are punishable by law. First, federal guidance, industry
advisories, and best practices all stress the importance
of installing updated versions of operating system and
the software that supports system operations to protect
against vulnerabilities that have been discovered in
previously released versions. If new versions have not
yet been released, "patches" that fix known flaws are
often readily available and should be installed in the
interim. Updating operating systems and other software
to correct these vulnerabilities is important because
once vulnerabilities are discovered, technically sophisticated
hackers write scripts to exploit them and often post
these scripts to the Internet for the widespread use
of lesser skilled hackers. Since these scripts are easy
to use, many security breaches happen when intruders
take advantage of vulnerabilities for which patches
are available but system administrators have not applied
the patches. Second, Public Law 99-74 requires that
a warning message be displayed upon access to all federal
computer systems notifying users that unauthorized use
is punishable by fines and imprisonment. Not only does
the absence of a warning message fail to deter potential
intruders, but, according to the law, pursuing and prosecuting
intruders is more difficult if they have not been previously
made fully aware of the consequences of their actions.
Commerce has not fully instituted these two key measures to
prevent incidents. First, many bureau systems do not
have system software that has been updated to address
known security exposures.
For example, during our review, we discovered 20 systems
with known vulnerabilities for which patches were available
but not installed. Moreover,
all the bureaus we reviewed were still running older
versions software used on critical control devices that
manage network connections. Newer versions of software
are available that correct the known security flaws
of the versions that were installed. Second, in performing
our testing of network security, we observed that warning
messages had not been installed for several network
paths into Commerce systems that we tested.
Incident
Detection Capabilities Have Not Been Implemented
|
Even
though strong controls may not block all intrusions,
organizations can reduce the risks associated with such
events if they take steps to detect intrusions and the
consequent misuse before significant damage can be
done. Federal guidance
emphasizes the importance of using detection systems
to protect systems from the threats associated with
increasing network connectivity and reliance on information
systems. Additionally, federally funded activities,
such as CERT/CC, the Department of Energy's Computer
Incident Advisory Capability, and FedCIRC are available
to assist organizations in detecting and responding
to incidents.
Although
the CIO's July memo directs Commerce bureaus to monitor
their information systems to detect unusual or suspicious
activities, all the bureaus we reviewed were either
not using monitoring programs or had only partially
implemented their capabilities. For example, only two
of the bureaus had installed intrusion detection systems.
Also, system and network logs frequently had
not been activated or were not reviewed to detect possible
unauthorized activity. Moreover, modifications
to critical operating system components were not logged,
and security reports detailing access to sensitive data
and resources were not sent to data owners for their
review.
The
fact that bureaus we reviewed detected our activities
only four times during the 2 months that we performed
extensive external testing of Commerce networks, which
included probing over 1,000 system devices, indicates
that, for the most part, they are unaware of intrusions.
For example, although we spent several weeks probing
one bureau's networks and obtained access to many of
its systems, our activities were never detected. Moreover,
during testing we identified evidence of hacker activity
that Commerce had not previously detected. Without monitoring
their information systems, the bureaus cannot
·
know
how, when, and who performs specific computer activities,
·
be
aware of repeated attempts to bypass security, or
·
detect
suspicious patterns of behavior such as two users with
the same ID and password logged on simultaneously or
users with system administrator privileges logged on
at an unexpected time of the day or night.
As
a result, the bureaus have little assurance that potential
intrusions will be detected in time to prevent or, at
least, minimize damage.
|
Incident
Response
Procedures Have Not
Been Established
|
The
CIO's July memo also outlines how the bureaus are to
respond to detected incidents. Instructions include
responses such as notifying appropriate officials, deploying
an on-site team to survey the situation, and isolating
the attack to learn how it was executed.
Only
one of the seven bureaus reviewed has documented response
procedures. Consequently, we experienced inconsistent
responses when our testing was detected. For
example, one bureau responded to our scanning of their systems by scanning ours in
return.
In another bureau, a Commerce employee who detected
our testing responded by launching a software attack
against our systems. In neither case was bureau management
previously consulted or informed of these responses.
The
lack of documented incident response procedures increases
the risk of inappropriate responses. For example, employees
could
·
take
no action,
·
take
insufficient actions that fail to limit potential damage,
·
take
overzealous actions that unnecessarily disrupt critical
operations, or
·
take
actions, such as launching a retaliatory attack, that
could be considered improper.
|
Bureaus
Have Not Been Reporting Incidents
|
The
CIO's July memo specifically requires bureau employees
who suspect an incident or violation to contact their
supervisor and the bureau security officer, who should
report the incident to the department's information
security manager. Reporting detected incidents is important
because this information provides valuable input
for risk assessments, helps in prioritizing security
improvement efforts, and demonstrates trends of threats
to an organization as a whole.
The
bureaus we reviewed have not been reporting all detected
incidents. During our 2-month testing period, 16 incidents
were reported by the seven bureaus collectively, 10
of which were generated to report computer viruses.
Four of the other six reported incidents related to
our testing activities, one of which was reported after
our discovery of evidence of a successful intrusion
that Commerce had not previously detected and reported.
However, we observed instances of detected incidents
that were not reported to bureau security officers or
the department's information security manager. For example,
the Commerce employees who responded to our testing
by targeting our systems in the two instances discussed
above did not report either of the two incidents to
their own bureau's security officer.
By
not reporting incidents, the bureaus lack assurance
that identified security problems have been tracked
and eliminated and the targeted system restored and
validated. Furthermore, information about incidents
could be valuable to other bureaus and assist the department
as a whole to recognize and secure systems against general
patterns of intrusion.
|
Commerce
Does Not
Have An Effective Information
Security Management
Program
|
The
underlying cause for the numerous weaknesses we identified
in bureau information system controls is that Commerce
does not have an effective departmentwide information
security management program in place to ensure that
sensitive data and critical operations receive adequate
attention and that the appropriate security controls
are implemented to protect them. Our study of security
management best practices, as summarized in our 1998
Executive
Guide,
found that leading organizations manage their information
security risks through an ongoing cycle of risk management.
This management process involves
(1) establishing a centralized management function to
coordinate the continuous cycle of activities while
providing guidance and oversight for the security of
the organization as a whole, (2) identifying and assessing
risks to determine what security measures are needed,
(3) establishing and implementing policies and procedures
that meet those needs,
(4) promoting security awareness so that users understand
the risks and the related policies and procedures in
place to mitigate those risks, and
(5) instituting an ongoing monitoring program of tests
and evaluations to ensure that policies and procedures
are appropriate and effective. However, Commerce's information
security management program is not effective in any
of these key elements.
|
Centralized
Management
Is Weak
|
Establishing
a central management function is the starting point
of the information security management cycle mentioned
above. This function provides knowledge and expertise
on information security and coordinates organizationwide
security-related activities associated with the other
four segments of the risk management cycle. For example,
the function researches potential threats and vulnerabilities,
develops and adjusts organizationwide policies and guidance,
educates users about current information security risks
and the policies in place to mitigate those risks, and
provides oversight to review compliance with policies
and to test the effectiveness of controls. This central
management function is especially important to managing
the increased risks associated with a highly connected
computing environment. By providing coordination and
oversight of information security activities organizationwide,
such a function can help ensure that weaknesses in one
unit's systems do not place the entire organization's
information assets at undue risk.
According
to Commerce policy, broad program responsibility for
information security throughout the department is assigned
to the CIO. Department of Commerce Organization Order
15-23 of July 5, 2000, specifically tasks the CIO with
developing and implementing the department's information
security program to assure the confidentiality, integrity,
and availability of information and IT resources. These
responsibilities include developing policies, procedures,
and directives for information security; providing mandatory
periodic training in computer security awareness and
accepted practice; and identifying and developing security
plans for Commerce systems that contain sensitive information.
Furthermore, the CIO is also formally charged with carrying
out the Secretary's responsibilities for computer security
under OMB Circular A-130, Appendix III for all Commerce
bureaus and the Office of the Secretary.
An
information security manager under the direction of
the Office of the CIO is tasked with carrying out the
responsibilities of the security program. These responsibilities,
which are clearly defined in department policy, include
developing security policies, procedures, and guidance
and assuring security oversight through reviews, which
include tracking the implementation of required security
controls.
Commerce
lacks an effective centralized function to facilitate
the integrated management of the security of its information
system infrastructure. At the time of our review, the
CIO, who had no specific budget to fulfill security
responsibilities and exercised no direct control over
the IT budgets of the Commerce bureaus, stated that
he believed that he did not have sufficient resources
or the authority to implement the department information
security program. Until February 2000, when additional
staff positions were established to support the information
security manager's responsibilities, the information
security manager had no staff to discharge these tasks.
As of April 2001, the information security program was
supported by a staff of three.
Commerce
policy also requires each of its bureaus to implement
an information security program that includes a full
range of security responsibilities. These include appointing
a bureauwide information security officer as well as
security officers for each of the bureau's systems.
However,
the Commerce bureaus we reviewed also
lack their own centralized functions to coordinate bureau
security programs with departmental policies
and procedures and to implement effective programs for
the security of the bureaus' information systems infrastructure.
For example, four bureaus had staff assigned to security
roles on a part-time basis and whose security responsibilities
were treated as collateral duties.
In
view of the widespread interconnectivity of Commerce's
systems, the lack of a centralized approach to the management
of security is particularly risky since there is no
coordinated effort to ensure that minimal security controls
are implemented and effective across the department.
As demonstrated by our testing, intruders who succeeded
in gaining access to a system in a bureau with weak
network security could then circumvent the stronger
network security of other bureaus. It is, therefore,
unlikely that the security posture of the department
as a whole will significantly improve until a more integrated
security management approach is adopted and sufficient
resources allotted to implement and enforce essential
security measures departmentwide.
As
outlined in our 1998 Executive Guide, understanding
the risks associated with information security is the
second key element of the information security management
cycle. Identifying and assessing information security
risks helps to determine what controls are needed and
what level of resources should be expended on controls.
Federal guidance requires all federal agencies to develop
comprehensive information security programs based on
assessing and managing risks.
Commerce policy regarding information security requires
(1) all bureaus to establish and implement a risk management
process for all IT resources and (2) system owners to
conduct a periodic risk analysis for all sensitive systems
within each bureau.
Commerce
bureaus we reviewed are not conducting risk assessments
for their sensitive systems as required. Only 3 of the
bureaus' 94 systems we reviewed
had documented risk assessments, one of which was still
in draft. Consequently, most of the bureaus' systems
are being operated without consideration of the risks
associated with their immediate environment.
Moreover,
these bureaus are not considering risks outside their
immediate environment that affect the security of their
systems, such as network interconnections with other
systems. Although OMB Circular A-130, Appendix III,
specifically requires that the risks of connecting to
other systems be considered prior to doing so, several
bureau officials acknowledged that they had not considered
how vulnerabilities in systems that interconnected with
theirs could undermine the security of their own systems.
Rather, the initial decision to interconnect should
have been made by management based on an assessment
of the risk involved, the controls in place to mitigate
the risk, and the predetermined acceptable level of
risk. The widespread lack of risk assessments, as evidenced
by the serious access control weaknesses revealed during
our testing, indicates that Commerce is doing little
to understand and manage risks to its systems.
Security
Plans Are Not Prepared
Once
risks have been assessed, OMB Circular A-130, Appendix
III, requires agencies to document plans to mitigate
these risks through system security plans. These plans
should contain an overview of a system's security requirements;
describe the technical controls planned or in place
for meeting those requirements; include rules that delineate
the responsibilities of managers and individuals who
access the system; and outline training needs, personnel
controls, and continuity plans. In summary, security
plans should be updated regularly to reflect significant
changes to the system as well as the rapidly changing
technical environment and document that all aspects
of security for a system have been fully considered,
including management, technical, and operational controls.
None
of the bureaus we reviewed had security plans for all
of their sensitive systems. Of the 94 sensitive systems
we reviewed, 87 had no security plans. Of the seven
systems that did have security plans, none had been
approved by management. Moreover, five of these seven
plans did not include all the elements required by OMB
Circular A-130, Appendix III. Without comprehensive
security plans, the bureaus have no assurance that all
aspects of security have been considered in determining
the security requirements of the system and that adequate
protection has been provided to meet those requirements.
Systems
Are Not Authorized
OMB
also requires management officials to formally authorize
the use of a system before it becomes operational, when
a significant change occurs, and at least every 3 years
thereafter.
Authorization provides quality control in that it forces
managers and technical staff to find the best fit for
security, given technical constraints, operational constraints,
and mission requirements. By formally authorizing a
system for operational use, a manager accepts responsibility
for the risks associated with it. Since the security
plan establishes the system protection requirements
and documents the security controls in place, it should
form the basis for management's decision to authorize
processing.
As
of March 2001, Commerce management had not authorized
any of the 94 sensitive systems that we identified.
According to the more comprehensive data collected by
the Office of the CIO in March 2000, 92 percent of all
the department's sensitive systems had not been formally
authorized. The lack of authorization indicates that
systems' managers had not reviewed and accepted responsibility
for the adequacy of the security controls implemented
on their systems. As a result, Commerce has no assurance
that these systems are being adequately protected.
|
Needed
Policies Have Not Been Established
|
The
third key element of computer security management, as
identified during our study of information security
management practices at leading organizations, is establishing
and implementing policies. Security policies are important
because they are the primary mechanism by which management
communicates its goals and requirements. Federal guidelines
require agencies to frequently update their information
security policies in order to assess and counter rapidly
evolving threats and vulnerabilities.
Commerce's
information security policies are significantly outdated
and incomplete. Developed in 1993 and partially revised
in 1995, the department's information security policies
and procedures manual, Information
Technology Management Handbook, Chapter 10,
"Information Technology Security," and attachment, "Information
Technology Security" does not comply with OMB's February
1996 revision to Circular A-130, Appendix III, and does
not incorporate more recent NIST guidelines. For example,
Commerce's information security policy does not reflect
current federal requirements for managing computer security
risk on a continuing basis, authorizing processing,
providing security awareness training, or performing
system reviews. Moreover, because the policy was written
before the explosive growth of the Internet and Commerce's
extensive use of it, policies related to the risks of
current Internet usage are omitted. For example, Commerce
has no departmentwide security policies on World Wide
Web sites, e-mail, or networking.
Further,
Commerce has no departmental policies establishing baseline
security requirements for all systems. For example,
there is no departmental policy specifying required
attributes for passwords, such as minimum length and
the inclusion of special characters. Consequently, security
settings differ both among bureaus and from system to
system within the same bureau. Furthermore, Commerce
lacks consistent policies establishing a standard minimum
set of access controls. Having these baseline agencywide
policies could eliminate many of the vulnerabilities
discovered by our testing, such as configurations that
provided users with excessive access to critical system
files and sensitive data and expose excessive system
information, all of which facilitate intrusions.
The
Director of the Office of Information Policy, Planning,
and Review and the Information Security Manager stated
that Commerce management recognizes the need to update
the department information security policy and will
begin updating the security sections of the Information
Technology Management Handbook in the immediate
future.
|
Security
Awareness and
Training Are Not Adequately Promoted
|
The
fourth key element of the security management cycle
involves promoting awareness and conducting required
training so that users understand the risks and the
related policies and controls in place to mitigate them.
Computer intrusions and security breakdowns often occur
because computer users fail to take appropriate security
measures. For this reason, it is vital that employees
who use computer systems in their day-to-day operations
are aware of the importance and sensitivity of the information
they handle, as well as the business and legal reasons
for maintaining its confidentiality, integrity, and
availability.
OMB
Circular A-130, Appendix III, requires that employees
be trained on how to fulfill their security responsibilities
before being allowed access to sensitive systems. The
Computer Security Act mandates that all federal employees
and contractors who are involved with the management,
use, or operation of federal computer systems be provided
periodic training in information security awareness
and accepted information security practice. Specific
training requirements are outlined in NIST guidelines,
which establish a mandatory baseline of training in
security concepts and procedures and define additional
structured training requirements for personnel with
security-sensitive responsibilities.
Overall,
none of the seven bureaus had documented computer security
training procedures and only one of the bureaus had
documented its policy for such training. This bureau
also used a network user responsibility agreement, which
requires that all network users read and sign a one-page
agreement describing the network rules. Officials at
another bureau stated that they were developing a security
awareness policy document.
Although
each of the seven bureaus had informal programs in place,
such as a brief overview as part of the one-time general
security orientation for new employees, these programs
do not meet the requirements of OMB, the Computer Security
Act, or NIST Special Publication 800-16. Such brief
overviews do not ensure that security risks and responsibilities
are understood by all managers, users, and system administrators
and operators. Shortcomings in the bureaus' security
awareness and training activities are illustrated by
the following examples.
·
Officials at one bureau
told us that they did not see training as an integral
part of its security program, and provided an instructional
handbook only to users of a specific bureau application.
·
Another bureau used a generic
computer-based training course distributed by the Department
of Defense that described general computer security
concepts but was not specific to Commerce's computing
environment. Also, this bureau did not maintain records
to document who had participated.
·
Another bureau had limited
awareness practices in place such as distribution of
a newsletter to staff, but had no regular training program.
Officials at this bureau told us that they were in the
process of assessing its training requirements.
Only
one Commerce bureau that we reviewed provided periodic
refresher training. In addition, staff directly responsible
for information security do not receive more extensive
training than overviews since security is not considered
to be a full-time function requiring special skills
and knowledge. Several of the computer security weaknesses
we discuss in this testimony indicate that Commerce
employees are either unaware of or insensitive to the
need for important information system controls.

Policies
and Controls Are
Not Monitored
|
The
final key element of the security management cycle is
an ongoing program of tests and evaluations to ensure
that systems are in compliance with policies and that
policies and controls are both appropriate and effective.
This type of oversight is a fundamental element because
it demonstrates management's commitment to the security
program, reminds employees of their roles and responsibilities,
and identifies and corrects areas of noncompliance and
ineffectiveness. For these reasons, OMB Circular A-130,
Appendix III, directs that the security controls of
major information systems be independently reviewed
or audited at least every 3 years. Commerce policy also
requires information security program oversight and
tasks the program manager with performing compliance
reviews of the bureaus as well as verification reviews
of individual systems. The government information security
reform provisions of the fiscal year 2001 National Defense
Authorization Act require annual independent reviews
of IT security in fiscal years 2001 and 2002.
No
oversight reviews of the Commerce bureaus' systems have
been performed by the staff of Commerce's departmentwide
information security program. The information security
manager stated that he was not given the resources to
perform these functions. Furthermore, the bureaus we
reviewed do not monitor the effectiveness of their information
security. Only one of the bureaus has performed isolated
tests of its systems. In lieu of independent reviews,
in May 2000, the Office of the CIO, using a draft of
the CIO Council's Security Assessment Framework, requested
that all Commerce bureaus submit a self-assessment of
the security of their systems based on the existence
of risk assessments, security plans, system authorizations,
awareness and training programs, service continuity
plans, and incident response capabilities. This self-assessment
did not require testing or evaluating whether systems
were in compliance with policies or the effectiveness
of implemented controls. Nevertheless, the Office of
the CIO's analysis of the self-assessments showed that
92 percent of Commerce's sensitive systems did not comply
with federal security requirements. Specifically, 63
percent of Commerce's systems did not have security
plans that comply with federal guidelines, 73 percent
had no risk assessments, 64 percent did not have recovery
plans, and 92 percent had not been authorized for operational
use.
The
information security manager further stated that, because
of the continued lack of resources, the Office of the
CIO would not be able to test and evaluate the effectiveness
of Commerce's information security controls to comply
with the government information security reform provisions
requirement of the fiscal year 2001 National Defense
Authorization Act. Instead, the information security
manager stated that he would again ask the bureaus to
do another self-assessment and would analyze the results.
In future years, the information security manager intends
to perform hands-on reviews as resources permit.

In
conclusion, Mr. Chairman, the significant and pervasive
weaknesses that we discovered in the seven Commerce
bureaus we tested place the data and operations of these
bureaus at serious risk. Sensitive economic, personnel,
financial, and business confidential information are
exposed, allowing potential intruders to read, copy,
modify, or delete these data. Moreover, critical operations
could effectively cease in the event of accidental or
malicious service disruptions.
Poor
detection and response capabilities exacerbate the bureaus'
vulnerability to intrusions. As demonstrated during
our own testing, the bureaus' general inability to notice
our activities increases the likelihood that intrusions
will not be detected in time to prevent or minimize
damage.
These
weaknesses are attributable to the lack of an effective
information security program, that is, lack of centralized
management, a risk-based approach, up-to-date security
policies, security awareness and training, and continuous
monitoring of the bureaus' compliance with established
policies and the effectiveness of implemented controls.
These weaknesses are exacerbated by Commerce's highly
interconnected computing environment in which the vulnerabilities
of individual systems affect the security of systems
in the entire department, since a compromise in a single
poorly secured system can undermine the security of
the multiple systems that connect to it.
To
address these weaknesses, we are recommending that the
Secretary
·
direct the Office of the
CIO and the bureaus to develop and implement an action
plan for strengthening access controls for Commerce's
systems commensurate with the risk and magnitude of
the harm resulting from the loss, misuse, or modification
of information resulting from unauthorized access. Specifically,
this action plan should address the logical access control
weaknesses and other information system weaknesses that
are summarized in our draft report,
·
direct the Office of the
CIO to establish a departmentwide incident handling
function with formal procedures for preparing for,
detecting, responding to, and reporting incidents,
and
·
direct the Office of the
CIO to develop and implement an effective departmentwide
security program.
Such a program should include establishing a
central information security function to manage an ongoing
cycle of the following security activities:
-
assessing risks and evaluating
needs,
-
updating the information
security program policies,
-
developing and implementing
a computer security awareness and training program,
and
-
developing and implementing
a management oversight process that includes periodic
compliance reviews and tests of the effectiveness of
implemented controls.
We
also recommend that the Secretary of Commerce, the Office
of the CIO, and the bureau CIOs direct the appropriate
resources and authority to fulfill the security responsibilities
that Commerce policy and directives task them with performing
and to implement these recommendations.
We
also recommend that the Secretary take advantage of
the opportunity that the installation of the new network
infrastructure will provide to improve security.
Mr.
Chairman, this concludes my statement. I would be pleased
to respond to any questions that you or other members
of the Committee may have at this time.
