Representative Greenwood, Members
of the subcommittee, thank you for inviting me here today
to speak to the important issue of intrusions into government
computer networks. The problem is serious. The Department
of Defense reports thousands of potential cyber attacks
launched against DoD systems. GAO reports that "in
1999 and 2000, the Air Force, Army, and Navy recorded a
combined total of 600 and 715 [serious] cyber attacks, respectively."
This does not even consider attacks on civilian agencies.
Two weeks ago National Security Advisor Condoleezza Rice
stated that "The President himself is on record as
stating that infrastructure protection is important to our
economy and to our national security and therefore it will
be a priority for this administration."
Dr. Rice also stated during
that same speech that, "We have to maximize our resources
and energies by making sure that they are focused, instead
of allowing them to be dissipated through dispersal."
The need for a coordinated interagency approach to address
intrusions into government networks was one of the principal
reasons for having established the National Infrastructure
Protection Center (NIPC). When the NIPC was founded three
years ago, it was during one of the largest intrusions ever
into U.S. government systems. The lessons learned from that
intrusion and from the response to it have helped shape
the NIPC.
Let me provide you with a snapshot
of our caseload on government intrusions. Currently we have
102 cases (of a current total of 1,219 pending cases) involving
computer i ntrusions into government systems. This includes
intrusions into federal, state and local systems, as well
as the military. It should be noted that a single case can
consist of hundreds of compromised systems that have experienced
thousands of intrusions. In addition, many agencies conduct
investigations concerning intrusions into their systems
that are not reported to the FBI. In short, this case load
represents a large number of incidents.
Several critical elements are
required to deal with intrusions into government computer
systems. There must be an interagency structure to deal
with this problem. No agency should or should have to address
these issues alone. Information must be shared with law
enforcement and the NIPC. We must work to ensure that any
intrusions are stemmed and the vulnerability that allowed
the intrusion is patched.
Interagency cooperation is
essential in dealing with intrusions into government systems.
As I said at the outset, that is why the NIPC was created.
Currently the NIPC has representatives from the following
agencies at the Center: FBI, Army, Navy, Air Force Office
of Special Investigations, Defense Criminal Investigative
Service, National Security Agency, United States Postal
Service, Department of Transportation/Federal Aviation Administration,
Central Intelligence Agency, Department of Commerce/Critical
Infrastructure Assurance Office, and the Department of Energy.
This representation has given us the unprecedented ability
to reach back into the parent organizations of our interagency
detailees on intrusions and infrastructure protection matters.
In addition, we have formed an interagency coordination
cell at the Center which holds monthly meetings with U.S.
Secret Service, U.S. Customs Service, representatives from
DoD investigative agencies, the Offices of Inspector General
of NASA, Social security administration, Departments of
Energy, State, and Education, and the U.S. Postal Service,
to discuss topics of mutual concern.
This representation is not
enough, however. The PDD states that, " The NIPC will
include FBI, USSS, and other investigators experienced in
computer crimes and infrastructure protection, as well as
representatives detailed from the Department of Defense,
the Intelligence Community and Lead Agencies." The
NIPC would like to see all lead agencies represented in
the Center. The more broadly representative the NIPC is,
the better job it can do in responding to intrusions into
government systems.
The NIPC is pursuing three
sets of activities that address computer intrusions into
government systems: prevention, detection, and response.
Prevention:
Our role in preventing cyber
intrusions into government systems is not to provide advice
on what hardware or software to use or to act as a federal
systems administrator. Rather our role is to provide information
about threats, ongoing incidents, and exploited vulnerabilities
so that government and private sector system administrators
can take the appropriate protective measures. The NIPC has
a variety of products to inform the private sector and other
domestic and international government agencies of the threat,
including: alerts, advisories, and assessments; biweekly
CyberNotes; monthly Highlights; and topical
electronic reports. These products are designed for tiered
distribution to both government and private sector entities
consistent with applicable law and the need to protect intelligence
sources and methods, and law enforcement investigations.
For example, Highlights is a monthly publication
for sharing analysis and information on critical infrastructure
issues. It provides analytical insights into major trends
and events affecting the nation's critical infrastructures.
It is usually published in an unclassified format and reaches
national security and civilian government agency officials
as well as infrastructure owners. CyberNotes is another
NIPC publication designed to provide security and information
system professionals with timely information on cyber vulnerabilities,
hacker exploit scripts, hacker trends, virus information,
and other critical infrastructure-related best practices.
It is published twice a month on our website and disseminated
in hardcopy to government and private sector audiences.
The NIPC has elements responsible
for both analysis and warning. What makes the NIPC unique
is that it has access to all-source intelligence from law
enforcement, the intelligence community, private sector,
international arena, and open sources. No other entity has
this range of information. Complete and timely reporting
of incidents from private industry and government agencies
allows NIPC analysts to make the linkages between government
intrusions and private sector activity. We are currently
working on an integrated database to allow us to more quickly
make the linkages among seemingly disparate intrusions.
This database will leverage both the unique information
available to the NIPC through FBI investigations and information
available from the intelligence community and open sources.
Having these analytic functions at the NIPC is a central
element of its ability to carry out its preventive mission.
This initiative expands direct
contacts with the private sector infrastructure owners and
operators and shares information about cyber intrusions
and exploited vulnerabilities through the formation of local
InfraGard chapters within the jurisdiction of each of the
56 FBI Field Offices. This is critical to infrastructure
protection, since private industry owns most of the infrastructures.
Further, InfraGard's success belies the notion that private
industry will not share information with NIPC or law enforcement.
All 56 FBI field offices have InfraGard chapters. There
are currently over 900 InfraGard members. The national InfraGard
rollout was held on January 5, 2001.
The NIPC is also working with
the Information Sharing and Analysis Centers established
under the auspices of PDD-63. For example, the North American
Electric Reliability Council (NERC) serves as the electric
power ISAC. We have developed a program with the NERC to
develop an Indications and Warning System for physical and
cyber attacks. Under the program, electric utility companies
and other power entities transmit incident reports to the
NIPC. These reports are analyzed and assessed to determine
whether an NIPC alert, advisory, or assessment is warranted
to the electric utility community. Electric power participants
in the pilot program have stated that the information and
analysis provided by the NIPC back to the power companies
make this program especially worthwhile. NERC has recently
decided to expand this initiative nationwide. This initiative
will serve as a good example of government and industry
working together to share information and the Electrical
Power Indications and Warning System will provide a model
for the other critical infrastructures. Eventually the NIPC
will need to be able to have a comprehensive nation-wide
system for all the infrastructures.
The NIPC is the Sector Lead
Agency for the Emergency Law Enforcement Services sector.
As part of this mission, the Center has also been asked
to by ELES Sector the to have the NIPC Watch and Warning
Unit act as the ISAC for the sector. The NIPC is working
to implement this request.
Detection:
Given the ubiquitous vulnerabilities
in existing Commercial Off-the-Shelf (COTS) software, intrusions
into critical systems are inevitable for the foreseeable
future. Thus detection of these intrusions is critical if
the U.S. Government and critical infrastructure owners and
operators are going to be able to respond. To improve our
detection capabilities, we first need to ensure that we
are fully collecting, sharing, and analyzing all extant
information from all relevant sources. It is often the case
that intrusions can be discerned simply by collecting bits
of information from various sources; conversely, if we don't
collate these pieces of information for analysis, we might
not detect the intrusions at all. Thus the NIPC's role in
collecting information from all sources and performing analysis
in itself serves the role of detection.
Agency system administrators
need to work with FedCIRC and the NIPC. PDD-63 makes clear
the importance of such reporting. It states, "All
executive departments and agencies shall cooperate with
the NIPC and provide such assistance, information and advice
that the NIPC may request, to the extent permitted by law.
All executive departments shall also share with the NIPC
information about threats and warning of attacks and about
actual attacks on critical government and private sector
infrastructures, to the extent permitted by law." Currently
OMB has instructed the agencies that they must report their
intrusions to FedCIRC, but reporting to the NIPC is not
mentioned. We are working with FedCIRC to define criteria
for reporting of incidents to the NIPC for analytical as
well as investigative purposes.
In some cases, in response
to victims' reports, the NIPC has sponsored the development
of tools to detect malicious software code. For example,
in December 1999, in anticipation of possible Y2K related
malicious conduct, the NIPC posted a detection tool on its
web site that allowed systems administrators to detect the
presence of certain Distributed Denial of Service (DDoS)
tools on their networks. In these cases, hackers plant tools
such as Trinoo, Tribal Flood Net (TFN), TFN2K, or Stacheldraht
(German for barbed wire) on a number of unwitting victim
systems. Then when the hacker sends the command, the victim
systems in turn begin sending messages against a target
system. The target system is overwhelmed with the traffic
and is unable to function. Users trying to access that system
are denied its services. The NIPC's detection tools were
downloaded thousands of times and have no doubt prevented
many DDoS attacks.
The NIPC also led the FBI's
multiagency Y2K command center. NIPC personnel were on alert
during the rollover period watching for possible malicious
activity under the guise of Y2K. NIPC coordinated a nationwide
watch effort and distributed reports every four hours round
the clock on the situation.
Regarding warning, if we determine
that an intrusion is imminent or underway, the NIPC Watch
is responsible for formulat ing assessments, advisories,
and alerts, and quickly disseminating them. The substance
of those products will come from analytical work done by
NIPC analysts. If we determine an attack is underway, we
can notify both private sector and government entities using
an array of mechanisms so they can take protective steps.
In some cases these warning products can prevent a wider
attack; in other cases warnings can mitigate an attack already
underway. Finally, these notices can prevent attacks from
ever happening in the first place. For example, the NIPC
released an advisory on March 30, 2001 regarding the "Lion
Internet Worm," which is a DDoS tool targeting Unix-based
systems. Based on all-source information and analysis, the
NIPC alerted systems administrators how to look for this
compromise of their system and what specific steps to take
to remove the tools if they are found. This alert was issued
after consultation with FedCIRC, JTF-CND, a private sector
ISAC, and other infrastructure partners.
Response:
Despite our efforts, we know
that government systems will continue to be attacked. Thus
we need to determine the origin of these attacks in order
to get to the person behind the keyboard for our government
to formulate the appropriate response. In the cyber world,
determining what is happening is difficult at the early
stages. An event could be a system probe to find vulnerabilities
or entry points, an intrusion to steal data or plant sniffers
or malicious code, an act of teenage vandalism, an attack
to disrupt or deny service, or even an act of war. The crime
scene itself is totally different from the physical world
in that it is dynamic--it grows, contracts, and can change
shape. Further, the tools used to perpetrate a major infrastructure
attack can be the same ones used for other cyber intrusions
(simple hacking, foreign intelligence gathering, organized
crime activity to steal property, data, etc...), making
identification more difficult. Determining that an event
is even occurring thus can often be difficult in the cyber
world, and usually a determination cannot be made without
a thorough investigation. In the physical world one can
see instantly if a building has been bombed or an airliner
brought down. In the cyber world, an intrusion may go undetected
for some time.
Identification of the perpetrators
and their objectives during an event is critical especially
in the initial stages. The perpetrators could be criminal
hackers, teenagers, electronic protestors, terrorists, or
foreign intelligence services. In order to attribute an
attack, the NIPC coordinates an investigation that gathers
information from within the United Sates using either criminal
investigative or foreign counter-intelligence authorities,
depending on the circumstances. We also rely on the assistance
of other nations when appropriate. Obtaining reliable information
is necessary not only to identify the perpetrator but also
to determine the size and nature of the intrusion: how many
systems are affected, what techniques are being used, and
what is the purpose of the intrusions--disruption, economic
espionage, theft of money, etc...
Relevant information could
come from existing criminal investigations or other contacts
at the FBI Field Office level. It could come from the U.S.
Intelligence Community, other U.S. Government agency information,
through private sector contacts, the media, other open sources,
or foreign law enforcement contacts. The NIPC's role is
to coordinate, collect, analyze, and disseminate this information.
Indeed this is one of the principal reasons the NIPC was
created.
Because the Internet by its
nature embodies a degree of anonymity, our government's
proper response to an attack first requires significant
investigative steps. Investigators typically need a full
range of criminal and/or national security authorities to
determine who launched the attack. Under our system the
legal authorities for conducting investigations within the
United States include: the Computer Fraud and Abuse Act,
the Economic Espionage Statute, the Electronic Communications
Privacy Act, the Foreign Intelligence Surveillance Act,
as well as the relevant executive orders delineating the
responsibilities of the intelligence community. Thus the
FBI can apply for court orders to get subscriber information
from Internet Service Providers, and monitor communications
under the Electronic Communications Privacy Act or under
the Foreign Intelligence Surveillance Act, depending on
the facts of the case as they are known at the time the
order is requested. The FBI has designated the NIPC to act
as the program manager for all of its computer intrusion
investigations, and the NIPC has made enormous strides in
developing this critical nationwide program. In that connection,
the NIPC works closely with the Criminal Division's Section
on Computer Crime and Intellectual Property, the Department's
Office of Intelligence Policy and Review, and the U.S. Attorney's
Offices in coordinating legal responses.
In the event of a national-level
set of intrusions into significant systems, the NIPC will
form a Cyber Crisis Action Team (C-CAT) to coordinate response
activities and use the facilities of the FBI's Strategic
Information and Operations Center (SIOC). The team will
have expert investigators, computer scientists, analysts,
watch standers, and other U.S. government agency representatives.
Part of the U.S. government team might be physically located
at FBI Headquarters and part of the team may be just electronically
connected. The C-CAT will immediately contact field offices
responsible for the jurisdictions where the attacks are
occurring and where the attacks may be originating. The
C-CAT will continually assess the situation and support/coordinate
investigative activities, issue updated warnings, as necessary,
to all those affected by or responding to the crisis. The
C-CAT will then coordinate the investigative effort to discern
the scope of the attack, the technology being used, and
the possible source and purpose of the attack.
While we have not seen an example
of cyber terrorism directed against U.S. government systems,
the NIPC's placement in the FBI' s counterterrorism division
will allow for a seamless FBI response in the event of a
terrorist action that encompasses both cyber and physical
attacks. The NIPC and the other elements of the FBI's Counterterrorism
Division have conducted joint operations and readiness exercises
in the FBI's SIOC. We are prepared to respond if called
upon.
Case Examples
Over the past several years
we have seen a wide range of cyber threats ranging from
defacement of websites by juveniles to sophisticated intrusions
sponsored by foreign powers, and everything in between.
Some of these are obviously more significant than others.
The theft of national security information from a government
agency or the interruption of electrical power to a major
metropolitan area would have greater consequences for national
security, public safety, and the economy than the defacement
of a web-site. But even the less serious categories have
real consequences and, ultimately, can undermine confidence
in e-commerce and violate privacy or property rights. A
web site hack that shuts down an e-commerce site can have
disastrous consequences for a business. An intrusion that
results in the theft of credit card numbers from an online
vendor can result in significant financial loss and, more
broadly, reduce consumers= willingness to engage in e-commerce.
Because of these implications, it is critical that we have
in place the programs and resources to investigate and,
ultimately, to deter these sorts of crimes.
In addition, because it is
often difficult to determine whether an intrusion or denial
of service attack, for instance, is the work of an individual
with criminal motives or foreign nation state, we must treat
each case as potentially serious until we gather sufficient
information to determine the nature, purpose, scope, and
perpetrator of the attack. While we cannot discuss ongoing
investigations, we can discuss closed cases that involve
FBI and other agency investigations in which the intruder's
methods and motivation were similar to what we are currently
seeing. A few illustrative are described below:
In hacker cases, the attacker's
motivation is just to see how far he can intrude into a
system. This seems to be the motivation for the California
teens in the well-known Solar Sunrise case. In this case
the intruders exploited a well known vulnerability in computers
that run on the Sun Solaris operating system. By exploiting
this vulnerability, the intruder can gain root access (total
control) of the system. As in the Solar Sunrise case, the
intruders can then install their own accounts on the system
and create backdoors into the system from which they can
then install additional programs to find passwords. They
also had the ability to alter, remove, or destroy data on
those systems. This case demonstrated to the interagency
community how difficult it is to identify an intruder until
all of the facts are gathered through an investigation,
and why assumptions cannot be made until sufficient facts
are available. The incident also vividly demonstrated the
vulnerabilities that exist in our networks; if these individuals
were able to assume "root access" to certain unclassified
DoD systems, it is not difficult to imagine what hostile
adversaries with greater skills and resources would be able
to do. Finally, Solar Sunrise demonstrated the need for
interagency coordination to deal with such attacks. The
perpetrators in this case were two 16 and an 18 years old.
We have also seen cases of
hacking and mischief for what might be termed personal reasons.
For example, Eric Burns, a.k.a Zyklon, hacked into the White
House web site as well as other sites. This case was worked
jointly by the U.S. Secret Service and the FBI. He was caught
and pled guilty to one count of 18 U.S.C.1030. In November
1999 he was sentenced to 15 months in prison, 3 years supervised
release, and ordered to pay $36,240 in restitution and a
$100 fine.
In another example, the Melissa
Macro Virus was reportedly named after an exotic dancer
from Florida; this virus wreaked havoc on government and
private sector networks in March 1999. He pled guilty to
one federal count of violating 18 U.S.C. 1030 and four state
counts. He admitted to causing $80 million in damage as
well. David Smith, the author of the virus, faces a maximum
sentence of five years and $250,000 on the federal charge.
He is currently awaiting sentencing. This is a good example
of how federal and state governments are increasingly coordinating
investigations and prosecutions in combating computer crime.
In another case, system penetration
coupled with theft can be the motivation. A Florida youth
admitted to breaking into 13 computers at the Marshall Space
Flight Center in Huntsville, Alabama in June 1999 and downloading
$1.7 million in NASA proprietary software that supports
the International Space Station's environmental systems.
NASA has estimated the cost to repair the damage at $41,000.
The subject has also admitted to entering Defense Department
systems of the Defense Threat Reduction Agency, intercepting
3,300 e-mail messages, and stealing passwords from Pentagon
computers. This case was investigated by NASA. He was sentenced
to six months in a juvenile detention center for hacking
into NASA computers which support the International Space
Station.
Virus writers have become a
more prevalent threat in recent years. We have seen virus
writers unleash havoc on the Internet for a variety of motivations.
In May 2000 companies and individuals around the world were
stricken by the ALove Bug,@ a virus (or, technically, a
Aworm@) that traveled as an attachment to an e-mail message
and propagated itself extremely rapidly through the address
books of Microsoft Outlook users. The virus/worm also reportedly
penetrated at least 14 federal agenciesCincluding the Department
of Defense (DOD), the Social Security Administration, the
Central Intelligence Agency, the Immigration and Naturalization
Service, the Department of Energy, the Department of Agriculture,
the Department of Education, the National Aeronautics and
Space Administration (NASA), along with the House and Senate.
Investigative work by the FBI=s
New York Field Office, with assistance from the NIPC, traced
the source of the virus to the Philippines within 24 hours.
The FBI then worked, through the FBI Legal Attaché in Manila,
with the Philippines= National Bureau of Investigation,
to identify the perpetrator. The speed with which the virus
was traced back to its source is unprecedented. The prosecution
in the Philippines was hampered by the lack of a specific
computer crime statute. Nevertheless, Onel de Guzman
was charged on June 29, 2000 with fraud, theft, malicious
mischief, and violation of the Devices Regulation Act. However,
those charges were dropped in August by Philippine judicial
authorities. As a postscript, it is important to note that
the Philippines= government on June 14, 2000 reacted quickly
and approved the E-Commerce Act, which now specifically
criminalizes computer hacking and virus propagation. The
Philippine government will not be hindered by insufficient
charging authorities should an incident like this one ever
occur again. Also, the NIPC continues to work with other
nations to provide guidance on the need to update criminal
law statutes.
In some cases, we have been
able to prevent the release of disastrous viruses against
public systems. On March 29, 2000, FBI Houston initiated
an investigation when it was discovered that certain small
businesses in the Houston area had been targeted by someone
who was using their Internet accounts in an unauthorized
manner and causing their hard drives to be erased. On March
30, 2000, FBI Houston conducted a search warrant on a residence
of an individual who allegedly created a computer "worm"
that seeks out computers on the Internet. This "worm"
looks for computer networks that have certain sharing capabilities
enabled, and uses them for the mass replication of the worm.
The worm causes the hard drives of randomly selected computers
to be erased. The computers whose hard drives are not erased
actively scan the Internet for other computers to infect
and force the infected computers to use their modems to
dial 911. Because each infected computer can scan approximately
2,550 computers at a time, this worm could have the potential
to create a denial of service attack against the E911 system.
The NIPC issued a warning to the public through the NIPC
webpage, SANS, NLETS, InfraGard, and teletypes to government
agencies. On May 15, 2000 Franklin Wayne Adams of Houston
was charged by a federal grand jury with knowingly causing
the transmission of a program onto the Internet which caused
damage to a protected computer system by threatening public
health and safety and by causing loss aggregated to at least
$5000. Adams was also charged with unauthorized access to
electronic or wire communications while those communications
were in electronic storage. He faces 5 years in prison and
a $250,000 fine.
Revenge by disgruntled employees
seems to be another strong motivation for attacks. Insiders
do not need a great deal of knowledge about computer intrusions,
because their knowledge of victim systems often allows them
to gain unrestricted access to cause damage to the system
or to steal system data. For example, in July 1997 Shakuntla
Devi Singla used her insider knowledge and another employee's
password and logon identification to delete data from a
U.S. Coast Guard personnel database system. It took 115
agency employees over 1800 hours to recover and reenter
the lost data. Ms. Singla was convicted and sentenced to
five months in prison, five months home detention, and ordered
to pay $35,000 in restitution.
Another case involved a National
Library of Medicine (NLM) employee. In January and February
1999 the National Library of Medicine computer system, relied
on by hundreds of thousands of doctors and medical professionals
from around the world for the latest information on diseases,
treatments, drugs, and dosage units, suffered a series of
intrusions where system administrator passwords were obtained
and hundreds of files downloaded, including sensitive medical
Aalert@ files and programming files that kept the system
running properly. The intrusions were a significant threat
to public safety and resulted in a monetary loss in excess
of $25,000. FBI investigation identified the intruder as
Montgomery Johns Gray, III, a former computer programmer
for NLM, whose access to the computer system had been revoked.
Gray was able to access the system through a Abackdoor@
he had created in the programming code. Due to the threat
to public safety, a search warrant was executed for Gray=s
computers and Gray was arrested by the FBI within a few
days of the intrusions. Subsequent examination of the seized
computers disclosed evidence of the intrusion as well as
images of child pornography. Gray was convicted by a jury
in December 1999 on three counts for violation of 18 U.S.C.
1030. Subsequently, Gray pleaded guilty to receiving obscene
images through the Internet, in violation of 47 U.S.C. 223.
Montgomery Johns Gray III was sentenced to 5 months prison,
5 months halfway house, 3 years probation and ordered to
pay $10,000 in restitution and assessments.
We are also seeing the increased
use of cyber intrusions by criminal groups who attack systems
for purposes of monetary gain. In September, 1999, two members
of a group dubbed the "Phonemasters" were sentenced
after their conviction for theft and possession of unauthorized
access devices (18 USC ' 1029) and unauthorized access to
a federal interest computer (18 USC ' 1030). The "Phonemasters"
were an international group of criminals who penetrated
the computer systems of MCI, Sprint, AT&T, Equifax,
and even the National Crime Information Center. The Phonemasters=
methods included "dumpster diving" to gather old
phone books and technical manuals for systems. They used
this information to trick employees into giving up their
logon and password information. The group then used this
information to break into victim systems. One member of
this group, Mr. Calvin Cantrell, downloaded thousands of
Sprint calling card numbers, which he sold to a Canadian
individual, who passed them on to someone in Ohio. These
numbers made their way to an individual in Switzerland and
eventually ended up in the hands of organized crime groups
in Italy. Cantrell was sentenced to two years as a result
of his guilty plea, while one of his associates, Cory Lindsay,
was sentenced to 41 months.
Terrorists groups are increasingly
using new information technology and the Internet to formulate
plans, raise funds, spread propaganda, and to communicate
securely. In his statement on the worldwide threat in 2000,
Director of Central Intelligence George Tenet testified
that terrorists groups, Aincluding Hizbollah, HAMAS, the
Abu Nidal organization, and Bin Laden=s al Qa=ida organization
are using computerized files, e-mail, and encryption to
support their operations.@ In one example, convicted terrorist
Ramzi Yousef, the mastermind of the World Trade Center bombing,
stored detailed plans to destroy United States airliners
on encrypted files on his laptop computer. While we have
not yet seen these groups employ cyber tools as a weapon
to use against critical infrastructures, their reliance
on information technology and acquisition of computer expertise
are clear warning signs. Moreover, we have seen other terrorist
groups, such as the Internet Black Tigers (who are reportedly
affiliated with the Tamil Tigers), engage in attacks on
foreign government web-sites and email servers. During the
riots on the West Bank in the fall of 2000, Israeli government
sites were subjected to e-mail flooding and "ping"
attacks. The attacks allegedly originated with Islamic elements
trying to inundate the systems with email messages. As one
can see from these examples overseas, Acyber terrorism@
B meaning the use of cyber tools to shut down critical national
infrastructures (such as energy, transportation, or government
operations) for the purpose of coercing or intimidating
a government or civilian population B is thus a very real
threat.
We have worked closely with
out international partners on computer intrusion cases,
including cases in which hackers have illegally accessed
U.S. government systems. In 1999 the FBI cooperated with
New Scotland Yard in the United Kingdom on a case in which
a UK citizen confessed to breaking into U.S. Navy systems.
He was further suspected of intruding into other systems,
including that of the U.S. Senate. He was sentenced to a
term of 3 years on a probation-like status.
We believe that foreign intelligence
services have adapted to using cyber tools as part of their
information gathering tradecraft. While I cannot go into
specific cases, there are overseas probes against U.S. government
systems every day. It would be naïve to ignore the possibilty
or even probability that foreign powers were behind some
or all of these probes. The motivation of such intelligence
gathering is obvious. By combining law enforcement and intelligence
community assets and authorities under one Center, the NIPC
can work with other agencies of the U.S. government to detect
these foreign intrusion attempts.
The prospect of "information
warfare" by foreign militaries against our critical
infrastructures is perhaps the greatest potential cyber
threat to our national security. We know that many foreign
nations are developing information warfare doctrine, programs,
and capabilities for use against the United States or other
nations. Knowing that they cannot match our military might
with conventional or Akinetic@ weapons, nations see cyber
attacks on our critical infrastructures or military operations
as a way to hit what they perceive as America=s Achilles
heel B our growing dependence on information technology
in government and commercial operations. For example, two
Chinese military officers recently published a book that
called for the use of unconventional measures, including
the propagation of computer viruses, to counterbalance the
military power of the United States.
Conclusion
While the NIPC has accomplished
much over the last three years in building the first national-level
operational capability to respond to cyber intrusions, much
work remains. We have learned from cases that successful
network investigation is highly dependent on expert investigators
and analysts, with state-of-the-art equipment and training.
We have built that capability both in the FBI Field Offices
and at NIPC Headquarters, but we have much work ahead if
we are to build our resources and capability to keep pace
with the changing technology and growing threat environment,
while at the same time being able to respond to several
major incidents at once.
We are building the international,
agency to agency, government to private sector, and law
enforcement partnerships that are vital to this effort.
The NIPC is well suited to foster these partnerships since
it has analysis, information sharing, outreach, and investigative
missions. We are working with the executives in the infrastructure
protection community with the goal of fostering the development
of safe and secure networks for our critical infrastructures.
While this is a daunting task, we are making progress.
Within the federal sector,
we have seen how much can be accomplished when agencies
work together, share information, and coordinate their activities
as much as legally permissible. But on this score, too,
more can be done to achieve the interagency and public-private
partnerships called for by PDD-63. We need to ensure that
all relevant agencies are sharing information about threats
and incidents with the NIPC and devoting personnel and other
resources to the Center so that we can continue to build
a truly interagency, "national" center. Finally,
we must work with Congress to make sure that policy makers
understand the threats we face in the Information Age and

of this Committee to address these vitally important issues.
Thank you.
