2123 Rayburn House Office Building
Mr. Scott Charney
Chief Trustworthy Computing Strategist
Microsoft Corporation
One Microsoft Way
Redmond, WA, 98052-6399
Chairman Stearns, Ranking Member Schakowsky, and Members of the
Subcommittee: My name is Scott Charney, and I am Microsoft's Chief
Trustworthy Computing Strategist. I want to thank you for the opportunity
to appear today to provide our views on cybersecurity and on what
we are doing to secure consumer data. I oversee the development
of strategies to create more secure software and services and to
enhance consumer security and privacy through our long-term Trustworthy
Computing initiative. My goal is to reduce the number of successful
computer attacks and increase the confidence of all computer users.
This is something I have worked toward throughout much of my career,
including during my service as chief of the Computer Crime and
Intellectual Property Section (CCIPS) in the Criminal Division
of the U.S. Department of Justice. While at CCIPS, I helped prosecute
nearly every major hacker case in the United States from 1991 to
1999.
At Microsoft, security is our number one priority, and as an
industry leader, we are committed to continually improving the
capability of our software to protect the privacy of consumers
and the security of their data. We are at the forefront of industry
efforts to enhance the security of computer programs and networks
and to educate consumers about good cybersecurity practices. We
also work closely with our partners in industry and governments
around the world to identify security threats to computer networks,
share best practices, improve our coordinated responses to security
breaches, and prevent computer attacks from happening in the first
place.
This hearing is exceptionally timely because of the rapid developments
in cybersecurity over the past two years. We wholeheartedly agree
with this Subcommittee that it is critical for all of us to address
consumer concerns about the privacy and security of their online
data in order to stimulate the further growth of e-commerce and
to help realize the Internet's full potential.
Today, I want to describe the risks posed to consumers' cybersecurity,
and the ways in which industry and government are working together
to protect consumers' online data. First, I will discuss the general
state of cybersecurity since November 2001, when we last appeared
before this Subcommittee; I will touch both on what has stayed
the same, and on what has changed. Second, I will discuss Microsoft's
ongoing efforts to help secure consumers' computer data. Third,
I will offer a few suggested steps that the government can take
to enhance the
security of consumer data.
I. Cybersecurity Since November 2001
The pursuit of cybersecurity involves a daily and never-ending
contest between industry, governments, and computer users, on the
one hand, and cyber criminals, on the other. Hackers remain elusive,
aggressive, and innovative. When we last testified before this
Subcommittee on this topic, the "ILOVEYOU," Code Red,
Ramen, Li0n, and Trinoo worms and viruses had already struck a
variety of operating systems. Since that time, criminal hackers
have unleashed Slapper, Scalper, Slammer, Blaster, SoBig, and many
other viruses and worms to infect computers, deny service, and
impair recovery.
There are no silver bullets in cybersecurity, and there will
always be vulnerabilities in complex software and systems, as well
as human errors made. As was true in 2001, cybersecurity involves
many layers and many collaborative partnerships, including software
design, software configuration, software patching, the sharing
of threat and vulnerability information, user education, user practices,
and the investigation and prosecution of cybercrime both within
the United States and internationally. In other words, cybersecurity
involves
management of technology as much as the technology itself.
Meanwhile, much has changed since we last testified before you.
Consumer dependence on the Internet has grown, and consumers are
more frequently sharing their personal information, including their
identities, contact information, financial data, and health information,
over the Internet. Moreover, as the personal computer becomes more
central to the daily lives of many citizens and to the daily functions
of the public and private sectors, the government, consumers, and
business enterprises are storing more personal information on their
Internet-connected computers and networks, thus potentially exposing
their data to hackers even if that personal information is never
transmitted over the Internet. In addition, consumers with broadband
are, unlike those with a dial-up connection, connected to the Internet
with unvarying IP addresses and at a high connection speed, and
therefore place consumer data at greater risk. As of March 2003,
30 million homes in America had a broadband connection to the Internet,
double the number who had a high-speed connection at home at the
end of 2001 and
a 50% increase from March 2002.
Another key change over the past two years is that the time between
the issuance of a patch and the time when we see a concrete exploit
taking advantage of the underlying vulnerability has dramatically
shortened. This time period is crucial because we have had very
few attacks that actually precede the patch; more typically, once
a patch is released, a race ensues between those installing the
patch to eliminate the vulnerability and those developing code
that exploits the vulnerability. When an exploit is developed faster,
enterprises and individuals have that much less time to learn of,
test, and install the patch before a hacker uses the exploit to
inflict damage. That window for the NIMDA virus was 331 days between
patch release and exploit; for Blaster, less than two years later,
it was only 26 days.
The chronology leading up to the criminal launch of the Blaster
worm illustrates the complex interplay between software companies,
security researchers, persons who publish exploit code, and hackers.
On July 16, we delivered a patch for the vulnerability and a security
bulletin to our customers. This was followed by ongoing outreach
to consumers, analysts, the press, our industry partners, and the
government. On July 25, nine days after we released the patch,
a security research group called XFOCUS published a tool to exploit
the vulnerability that the security bulletin and patch had highlighted.
In essence, XFOCUS analyzed our patch by reverse engineering it
to identify the vulnerability, then developed a means to attack
the vulnerability, and finally offered that attack to the world
so that any unsophisticated hacker could then unleash an attack
by downloading XFOCUS's work and using launch tools freely available
on the Internet.
At this point, we heightened our efforts to inform our customers
about the steps they should take to secure their computers. On
August 11, only 26 days after release of the patch, the Blaster
worm was discovered as it spread through the Internet. This sequence
of events underscores a dilemma: the same information that helps
customers to secure their systems also enables self-identified
security researchers and others to develop and publish exploit
code, which
hackers then use to launch damaging criminal attacks.
The sophistication and severity of cyberattacks are also increasing.
The Slammer worm in January 2003 did not attack the data of infected
systems, but resulted in a dramatic increase in network traffic
worldwide and in temporary loss of Internet access for some users.
This past summer, criminal hackers released the Blaster worm, which
spread by exploiting a security vulnerability for which we had
released a patch. Machines infected by Blaster used the network
connection to locate new, vulnerable machines, whereupon the worm
would copy itself, infect the new machine, and continue the process.
Blaster affected Windows NT4, Windows XP, Windows 2000, and Windows
Server 2003 systems, but could not reach those machines that were
patched and defended by a properly configured firewall. The worm
also tried to deny service to those users seeking to download the
patch for
Blaster.
In addition, cybercriminals have been able to make viruses more
prevalent and
harder for consumers to detect by "spoofing" legitimate email addresses,
which makes it more difficult to determine who the real sender is. In 2002, there
were twice as many email viruses as there were in 2001. In January 2003, the
SoBig virus spoofed email addresses and contained infectious .pif attachments,
which if opened would infect the user's computer and search the infected user's
hard drive for email addresses of possible further victims. Multiple variants
of the SoBig virus surfaced during the year. It is important to note that SoBig
did not exploit any software vulnerability; it was a social engineering attack
based on users' willingness to trust email that appeared to be from individuals
whom they knew.
In response to these threats, industry has increased tremendously
the resources and priority it devotes to cybersecurity issues.
Many of those efforts continue today, and I will describe them
in more detail in the next Section. Over the past two years, the
government has also taken significant steps during this time period
to address these heightened risks for online consumers. We commend
these actions as important steps in our shared journey toward enhanced
cybersecurity.
First and foremost, the Department of Homeland Security created
the National Cyber Security Division (NCSD) under the Department's
Information Analysis and Infrastructure Protection Directorate.
The NCSD is established to provide 24 x 7 functions, including
cyberspace analysis, issuing alerts and warning, improving information
sharing, responding to major incidents, and aiding in national-level
recovery efforts. The Department created the NCSD as part of its
implementation of the Homeland Security Act of 2002 and the National
Strategy to Secure Cyberspace, which the White House released in
February 2003 after soliciting extensive comments from consumers,
industry, and other government actors. We worked with government
officials in all of these activities, and we are encouraged by
the work DHS has done to date. Moreover, I personally look forward
to co-chairing a task force at its December "National Cyber
Security
Summit."
Second, the United States signed the Council of Europe Convention
on Cybercrime in November 2001. The Convention requires parties
to have minimum procedural tools to investigate such attacks, and
to facilitate international cooperation in investigating those
attacks. Because of the inherently international nature of cybercrime,
the Council of Europe cybercrime treaty is an important step towards
the transborder cooperation that is vital to combating cybercrime
and protecting consumers. We look forward to the day when the treaty
is sent to the
Senate for its consideration.
II. Our Response to Cybersecurity Threats Today
Security is Microsoft's top priority. We have devoted and will
continue to devote enormous resources to enhancing security. As
we confront new challenges and develop new approaches and new partnerships,
we continue to learn that perfect security in cyberspace is unattainable,
just as it is in the physical world. Operating system software
is one of the most complex items that humans have created, and
it is impossible to eliminate all software vulnerabilities. Thus,
we know that security is a journey rather than a destination, and
it can only be improved by partnerships involving government, industry,
responsible security researchers, and customers around the world
including government agencies, enterprises, and individual users.
Two years ago before this committee, my friend and co-panelist
Howard Schmidt properly stated, "We know that there is no
finish line to these efforts, but by working as we have with industry
peers - including some of these panelists - and with governments,
we have a chance to keep one step ahead of cyber-criminals."
A. Trustworthy Computing
In January 2002, Bill Gates launched our Trustworthy Computing
initiative, which involves every aspect of Microsoft and focuses
on four key pillars: security, privacy, reliability, and business
integrity. Security involves designing programs and systems that
are resilient to attack so that the confidentiality, integrity,
and availability of data and systems are protected. The goal of
our privacy efforts is to give individual consumers greater control
over their personal data and to ensure, as with the efforts against
spam, their right to be left alone. Reliability means creating
software and systems that are dependable, available when needed,
and perform at expected levels. Finally business integrity means
acting with honesty and integrity at all times, and engaging openly
and transparently with customers.
Under the security pillar, we are working to create software
and services for all of our customers that are Secure by Design,
Secure by Default, and Secure in Deployment, and to communicate
openly about our efforts.
- "Secure by Design" means two things: writing more
secure code and
architecting more secure software and services.
- "Secure by Default" means that computer software
is more secure out of the box, with features turned off until
needed and turned on by the users, whether it is in a home environment
or an IT department.
- "Secure in Deployment" means making it easier for
consumers, commercial and government users, and IT professionals
to maintain the security
of their systems.
- "Communications" means sharing what we learn both
within and outside of Microsoft, providing clear channels for
people to talk with us about security issues, and addressing
those issues with governments, our industry counterparts, and
the public.
The Trustworthy Computing goals are real and specific, and this
effort is now ingrained in our culture and is part of the way we
value our work.
We have enhanced the training of our developers to put security
at the heart of software design and at the foundation of the development
process. Security is and will continue to be our highest software
development priority. All new software releases and service packs
are now subject to an enhanced security release process which has
already resulted in a notable decline of vulnerabilities in some
of our server software. This effort, which can cost hundreds of
millions of dollars and delay the software's release to the market,
is a critical step in improving software security and reliability.
We are seeing a quantifiable and dramatic decrease in vulnerabilities:
for example, Windows Server 2003 followed this process and in the
first ninety days, we reported and patched three critical or important
security vulnerabilities and six total in the first 180 days. Whereas
in Windows Server 2000, we found eight critical or important vulnerabilities
in the first ninety days, and twenty one in the first
180 days.
When an attack does occur, our Microsoft Security Response Center
(MSRC) coordinates the investigation of reported vulnerabilities,
the development of patches, and our customer outreach efforts.
We are very proud of this organization and believe it represents
the industry's state of the art response
center.
Although we have made major strides, much work on Trustworthy
Computing remains ahead of us. One key piece of that work is the
Next-Generation Secure Computing Base (NGSCB). This is an on-going
research and development effort to help create a safer computing
environment for users by giving them access to four core hardware-based
features missing in today's PCs: strong process isolation, sealed
storage, a secure path to and from the user, and strong assurances
of software identity. These changes, which require new PC hardware
and software, can provide protection against malicious software
and enhance user privacy, computer security, data protection and
system integrity.
Part of Trustworthy Computing involves communicating with our
customers. In the wake of Blaster, we launched the Protect Your
PC campaign, urging customers to take three steps to improve their
security: install and/or activate an Internet firewall, stay up
to date on security patches, and install an anti-virus solution
and keep it up to date. The www.microsoft.com/protect web site
serves as the focal point for the campaign. We also provide a wide
range of free security tools and prescriptive guidance to make
it easier for consumers to make their computers and their data
more secure.
B. Streamlining the Patching Process
Patch management is a significant issue. We recognize that the
most important solution is to reduce the number of vulnerabilities
in code, thus reducing the need for patching. This is why we are
emphasizing secure by design. But no operating system - regardless
of development model - will ever be free of all vulnerabilities.
We must manage this risk by providing customers with simple and
easy to use patches. To streamline those processes, we are taking
the following
steps:
- Improving our testing of patches to ensure patch quality.
- Reducing the number of patch installers to provide users with
a consistent
patch experience, and make patching simpler.
- Working to ensure that each patch is reversible, so a rollback
is possible if deployment raises an unanticipated issue, such
as adversely affecting a legacy
application.
- Ensuring that patches register their presence on the system
- and producing improved scanning tools - so a user can quickly
determine if his or her machine
is patched appropriately.
- Making our security patch releases more predictable. We are
now providing security updates once a month, but we will still
provide patches outside this schedule when necessary, such as
when exploit code is publicly available.
- Avoiding reboot of the computer where practicable, as our
customers are more likely to apply a patch more quickly, if server
availability will not be
interrupted.
- Producing specific technology, such as Software Update Services
and Systems Management Server, so enterprises can download patches,
test them in their unique environments, and then easily deploy
them.
- Informing customers about the AutoUpdate feature in recent
Microsoft operating systems, which can automatically download
updates and then either install them as scheduled or request
permission from the user to do so.
C. Securing Enterprises to Protect Consumers
As noted, protecting consumer security depends, in part, on protecting
the security of enterprise servers, which often hold valuable consumer
data. Steve Ballmer, Microsoft's Chief Executive Officer, announced
last month that we are working to secure these networks from the
hazards that arise when users log into those networks from home
or other remote locations. Those hazards include malicious e-mails,
viruses and worms, malicious web content, and buffer
overruns.
While patches remain part of the solution, we are developing
what we call safety technology to secure these networks at the
perimeter by:
- Reducing the risk from computers such as notebooks and portable
computers that are moved between an enterprise's network and
external networks.
- Improving browsing technologies to minimize the risk of hostile
web sites
executing malicious code on visiting users' computers.
- Enhancing memory protection to help prevent successful buffer
overrun
attacks.
- Improving the Internet Connection Firewall within Windows
while also working closely with partners in the software security
industry.
Through these measures, we hope to help protect machines even
when not patched, thus giving enterprises more time to test and
deploy patches and enabling enterprises to patch on their schedule,
not on a schedule determined by hackers.
We are also providing new information and guidance on how enterprises
can secure their computers to protect data, including the personal
information of their
customers.
D. Industry Partnerships
We embrace our role in providing more secure computing for all
our customers. Because security is an industry-wide issue, we participate
actively in partnerships that span the industry, customers and
both the public and private sectors to encourage customers to implement
software in more secure ways.
For example, we are a founding member of the Organization for
Internet Safety (OIS), an alliance of leading technology vendors,
security researchers, and consultancies that is dedicated to the
principle that security researchers and vendors should follow common
processes and best practices to efficiently resolve security issues
and to ensure that Internet users are protected.
We also work with the Virus Information Alliance (VIA), a centralized
resource for Internet users seeking information about the latest
virus threats. Through its member companies, Microsoft, Network
Associates, Trend Micro, Computer Associates, Sybari, and Symantec,
the VIA offers recommended best practices for preventing malicious
attacks, information about specific viruses, how-to articles and
links to other anti-virus resources on its web site.
I am personally participating with some of my co-panelists in
the Global Council of Chief Security Officers, a newly formed think
tank that will share information with member companies and governments
on cybersecurity issues and enhance the involvement of private
sector officials in cybersecurity issues.
We also helped found the Information Technology - Information
Sharing and Analysis Center (IT-ISAC) and I serve on its board
today. The IT-ISAC coordinates information-sharing on cyber-events
among information technology
companies and the government.
E. Anti-Virus Reward Program
Two years ago we spoke about the need to increase deterrence
of criminal hacking. Although the Cyber Security Enforcement Act
passed this Congress last year, there is still much more that needs
to be done. Despite the best and laudable efforts of dedicated
law enforcement personnel, far too many hackers unleash their malicious
code or commit crimes with no punishment, as evidenced by the fact
that the authorities have yet to bring to justice the criminals
who launched major attacks like Blaster, NIMDA and Slammer. This
is an untenable situation, and it is one the nation allows to persist
in no other area. We need a robust deterrent to criminal activity
online.
When criminal attacks are launched, we work with law enforcement
officials to support their investigations. And earlier this month,
we took a significant step to support them by creating the Anti-Virus
Reward Program to provide monetary rewards for information resulting
in the arrest and conviction of hackers. For example, we have announced
a reward of $250,000 each for information leading to the arrest
and conviction of those responsible for the SoBig virus and the
Blaster worm.
To use a medical analogy, we are strengthening the Internet's
immune system through initiatives such as the anti-virus reward
program, our technical and legal anti-spam efforts, consumer education,
and efforts to secure existing systems and to make security integral
to new systems and applications. In the meantime, interim treatment
will be necessary.
III. The Government's Role
The government continues to play a key role in efforts to secure
consumers' software and data. We have recently collaborated with
the Department of Homeland Security to raise awareness of cyberthreats
through release of security bulletins. Such partnering between
industry and the government is a vital step toward additional cybersecurity
for consumers. I want to outline a few specific areas where government
initiatives can be particularly helpful in promoting
cybersecurity.
First, sustained public support of research and development continues
to play a vital role in advancing the IT industry's efforts to
secure consumers' software and data. A major portion of our $6.9
billion annual R&D investment goes to security, and accordingly,
we support additional federal funding for basic cybersecurity research
and development (R&D), including university-driven research.
The public sector should increase its support for basic research
in technology and should maintain its traditional support for transferring
the
results of federally-funded R&D under permissive licenses to the private
sector so that all industry participants can further develop the technology and
commercialize it to help make all software more secure.
Second, the government can lead by example by securing its own
systems through the use of reasonable security practices, buying
software that is engineered for security, and providing better
training for government systems administrators. We also hope government
will continue to promote security awareness among both home consumers
and businesses - as the Federal Trade Commission did in its information
campaign featuring Dewie the Turtle.
Third, government and industry should continue to examine and
reduce barriers to appropriate exchanges of information, and to
build mechanisms and interfaces for such exchanges. One encouraging
step in this direction is the NCSD's recent creation of the National
Computer Emergency Response Team (US-CERT). This coordination center,
for the first time, links public and private response capabilities
to facilitate communication of critical security information throughout
the Internet community.
Fourth, it will take increased government commitment to root
out those who hack into computers and propagate destructive worms
and viruses that harm millions of computer users. Therefore, law
enforcement should receive additional resources, personnel, and
equipment in order to investigate and prosecute cyber crimes. We
also support tough penalties on criminal hackers, such as forfeiture
of personal
property used in committing these crimes.
Fifth, because cybersecurity is inherently an international problem
with international solutions, greater cross-jurisdictional cooperation
among law
enforcement is needed for investigating cyber-attacks.
CONCLUSION
We will continue to pursue Trustworthy Computing and to work
closely with our partners in the computer, software, and communications
industries, the government, and our customers to enhance cybersecurity.
In the end, a shared commitment to reducing cybersecurity risks
and a coordinated response to cybersecurity threats of all kinds
- one that is based on dialogue and cooperation between the public
and private sectors - offer the greatest hope for protecting the
privacy of consumer data, enhancing the confidence of consumers
in the Internet, and fostering the growth of a vibrant, trustworthy
online
economy. |
