Cooperation between
the government and industry is essential to protecting the nation's information
infrastructure.
During the past several years, military
officials have become concerned about the possibility that a foreign adversary might
strike at U.S. computers, communications networks, and databases. Although such an
"information warfare" attack could be part of a larger conventional military
operation, it is also possible that an adversary might use information warfare (or IW, to
use the Pentagon shorthand) as a warning shot to dissuade the United States from helping
an ally abroad or as part of a limited terrorist campaign.
IW presents special problems for U.S. defense
planners. Many, if not most, targets of an IW attack against the United States would
probably be commercial computer and communications systems. These systems are more
vulnerable than those operated by the military. Commercial operators are seemingly unaware
that they are potential IW targets, and few have taken any precautionary measures.
Commercial software developers and hardware designers are also not attuned to the IW
threat. Thanks to "Melissa," the "Love Bug," and other computer
viruses, the public has become more aware of the importance of computer security. Several
recent cases of cyber crime and denial-of-service (DoS) attacks have also made computer
users more alert. Yet the IW threat is very different from vandalism and criminal
activities.
Foreign military organizations and terrorist
groups are likely to have more people and deeper pockets. They can work harder and longer
on an assignment, which means that they can crack systems that might withstand an assault
by a more casual opponent. They are likely to be more experienced and will use more
sophisticated tactics. Most important, serious IW attackers would not reveal their
activities until it is absolutely necessary. Unlike the typical hacker prankster who wants
to attract as much attention as possible, sophisticated IW threats have an incentive to
remain discreet and are likely to have the skills to evade detection. They would take
weeks or months to lay the groundwork for an attack in secret and would then create
diversions to confuse their targets so that the initial phases of an attack would be as
effective as possible.
The dilemma for U.S. officials is that although
commercial information systems are prime targets for IW attack, the government has limited
influence over how these systems are designed, manufactured, and operated. The public is
generally unaware of serious IW threats. It is hard to prove that a specific IW threat
exists, let alone that it is planning to strike a specific target. Companies are always
under pressure to reduce costs and maximize profit. All these factors make preparing for
IW difficult.
But one factor makes preparing for IW harder
than it needs to be. The relationship between the government and information industries
has often been rocky in recent years. The two communities are often unfamiliar with each
other and view their counterparts with suspicion. There is, in effect, a cultural divide
between the government and the commercial sector that prevents the two communities from
cooperating. Unless government officials and the information industries improve their
relationship, the United States will become increasingly vulnerable as it becomes more
dependent than ever on computers and the networks that interconnect them.
Commercial vulnerability
Virtually every aspect of life has become more
dependent on computers, imbedded electronics, and communications systems. All these
information systems--and especially those connected to a network--are potential targets
for IW attack. When defense experts talk about the IW threat to commercial information
systems, they do not mean hackers or even criminals. They are referring to well-funded,
sophisticated, foreign military powers, intelligence organizations, and terrorist groups.
Professional military journals in several countries, including Russia and China, have
discussed computer network attacks as a military option. Usually these writers refer to
foreign IW capabilities and plans, but it is reasonable to assume that any military
organization that has discussed foreign plans for IW has considered the option for itself.
One difficulty in preparing to defend against IW
is that the capabilities for such attacks are often easy to conceal, and the best IW
powers are also probably best at concealing their capabilities. Even so, one can postulate
what an IW team might look like. It might consist of a force of professional computer
network operators, not just a few technically savvy malcontents. These technicians will
know the holes that exist in popular software packages and the slip-ups network operators
commonly make in maintaining firewalls and other security measures. They will also know
from their own experience the shortcuts taken by sloppy or lazy operators.
Given enough time, such an IW force could
penetrate most systems connected to a public network, in part because they would have
ample support. An IW team would likely have an intelligence service helping it identify
the vulnerable points of an adversary's infrastructure and the computer systems they
depend on. The intelligence service would also support the IW team through traditional
espionage, such as stealing codebooks and passwords or planting agents who could assist an
attack from inside the targeted network. IW and intelligence organizations could also work
with each other to penetrate companies that produced or maintained commercial software.
This would enable them to insert "trapdoors" and "Trojan horses" that
they could trigger later.
In addition, the IW team would coordinate its
plans with the commanders of conventional military forces. The IW team could support a
conventional strike by jamming or confusing the enemy's air defense computer network, or
it could magnify the effects of a military strike by hacking the databases civilian
authorities need for fire and rescue operations. An IW team might spend weeks or months
"footprinting" targeted computer networks; in effect, creating a mirror image of
the system's design to identify its weak points. Once it had a footprint, the IW team
would update its analysis regularly, as is done with any military contingency plan. With
these plans in place, an IW team would be ready to go into action when needed. The
potential civilian targets of an IW strike could be any communications system or computer
network, or any part of a country's infrastructure that depends on such networks. For
example:
- U.S. military forces depend on commercial
transportation systems for logistics and, in many cases, for moving units to the scene of
battle. These transportation systems depend on computer networks to control machinery,
keep track of inventories, and coordinate their operations. A foreign adversary could
significantly hinder U.S. forces in reaching, say, the Persian Gulf or Taiwan Straits by
attacking the computers at commercial harbor facilities used to ship ammunition or the air
traffic control system that would be needed to support and airlift personnel and supplies.
- The commercial broadcast systems and commercial
Internet would be critical during a national emergency to coordinate public safety efforts
and keep the country informed. Some of the recent virus and DoS attacks were targeted
against companies such as CNN and AOL; it does not require much effort to imagine how
these companies might be forced to curtail operations by a more concerted, professionally
orchestrated strike.
- A serious opponent would probably target specific
suppliers and companies that are especially important to either U.S. weapons production or
mobilization. Attacks on small, seemingly unimportant companies might be lost in the heat
of a national crisis and might be hard for such companies to detect in any case.
- Most military and government personnel use the
same banks and financial institutions as the general public. If these are insecure, it
would be possible for an adversary to target the data records of key individuals, either
to collect compromising information or to plant disinformation.
Some writers have described how an IW attack
could lead to catastrophic results: the proverbial "electronic Pearl Harbor."
Such a strike might be theoretically possible, but it misses the point. IW is an
inevitable byproduct of the Information Revolution. Our foreign adversaries, both regular
military forces and terrorist organizations, will target U.S. information systems simply
because it is possible and because it offers them another channel for effective action. As
information systems become more capable, we become more dependent on them and, as we
become more dependent, they will become irresistible targets. That is why we need to
prepare defenses, and this requires cooperation between government and industry.
Deal with it
U.S. officials were reluctant even to discuss IW
threats until the mid-1990s, when they began to understand that it was impossible to
prepare for such attacks without greater public awareness of the problem. One of the first
studies to discuss the threat openly was a report published by the Defense Science Board
in 1996. This study, Information Warfare--Defense (IW-D), triggered more action. President
Clinton appointed a commission under retired Air Force General Robert T. Marsh to study
foreign threats to information systems and other infrastructure, such as transportation
and power generation. Several of the Marsh Commission's recommendations were later enacted
through Presidential Decision Directives 62 and 63, which President Clinton signed in May
1998. These directives officially acknowledged threats to the U.S. infrastructure
(including cyber attacks) and proposed measures to protect it. At the same time, the
president appointed a national coordinator for security, infrastructure protection, and
counterterrorism to oversee the implementation of the new policies.
Several obstacles undercut these efforts,
especially in their effectiveness against serious, well-supported IW threats. One problem
was a result of bureaucratic politics. Agencies competed for roles in dealing with the
newly acknowledged threat. The Department of Justice won the right in February 1998 to put
the National Infrastructure Protection Center (NIPC) in the FBI. The NIPC was, in effect,
supposed to be the federal government's command post for monitoring attacks on information
systems.
Unfortunately, the FBI is a law enforcement
organization. Although law enforcement organizations may be effective against hackers,
criminals, and the odd troublemaker, they are ill-equipped to deal with foreign military
threats and large international terrorist networks. Law enforcement organizations are
designed to respond to crimes, apprehend suspects, bring them to trial, and put them in
jail. Military organizations, in contrast, are designed to win wars. Both functions are
important, but each type of organization operates under different rules and at a different
tempo. Law enforcement is reactive and emphasizes dogged detective work. Defense is
preventive, and military operations aim at ending conflicts as expeditiously as possible
on terms favorable to the United States. Law enforcement requires respecting and
protecting the civil rights of defendants, who are presumed innocent until proven guilty.
Military operations frequently require violence and ruthlessness to defeat (and if
necessary, destroy) an adversary. It is hard to design an organization to do both, which
is, in effect, what the NIPC is expected to do.
There are other problems, too. Although the
military services and intelligence community have representatives at the NIPC, most of its
staff comes from law enforcement organizations. Even if defense and intelligence
organizations had greater representation at the NIPC, it would probably still be hard to
attract up-and-coming officers to serve there. Spending a few years at a law enforcement
organization monitoring hacker reports is hardly the ticket punch that gets a rising
officer promoted. Also, the NIPC is not well connected into the military command system.
For example, there do not appear to be clear guidelines that would define how and when a
hacking incident would be determined to be military problem rather than a criminal
investigation, and how the organization would change its operation to deal with such a
situation.
Meanwhile, military commanders have not
concentrated on protecting commercial systems from foreign attack. They have focused
mainly on ensuring that military computer systems and communications networks work. IW
attacks against targets within the United States, such as state-sponsored biological and
chemical weapon attacks, fall into the new mission of "homeland defense." The
military services are still not certain how to address this mission, as it is very
different from the kinds of operations U.S. forces prepared for throughout the 20th
century. Homeland defense requires new kinds of forces and new kinds of plans, many of
which do not fit into the traditional concepts of how a military force should operate. It
also raises legal issues; just as law enforcement organizations are unsuited to dealing
with military threats, U.S. military forces are prohibited by statute from serving in a
law enforcement function.
In addition to creating the NIPC, the federal
government has undertaken several other initiatives to reduce the threat of cyber crime
and cyber terrorism. Some of these involve partnerships with industry, but there are also
problems that leave the government and the private sector ill-prepared to respond jointly
against serious IW threats. For example, several reporting organizations have been
established to share information and issue warnings about hacker attacks and computer
viruses. One of the first of these was the Computer Emergency Response Team/Coordination
Center (CERT/CC) at Carnegie Mellon University. CERT/CC was set up as a federally funded
R&D center by the Defense Advanced Research Projects Agency in December 1988 after an
early virus attack disabled 10 percent of the computers then connected to the Internet.
Since then, CERT/CC has effectively become the 911 number that civilian computer operators
call to report such incidents. Other organizations in the United States and abroad have
since established local CERTs and reporting operations. The FBI also has its Awareness of
National Security Issues and Response (ANSIR) Program, which alerts industry and
infrastructure operators to espionage and sabotage threats.
During its last year in office, the Clinton
administration stepped up its efforts to deal with cybersecurity issues. One of its most
visible initiatives was unveiled in February 2000, when the president announced he would
provide $9 million in accelerated funding for computer security education programs and a
new Institute for Information Infrastructure Protection. (This was to supplement $2
billion the administration had already proposed for cybersecurity initiatives in FY 2001.)
The administration also planned to encourage industry to create new Information Sharing
and Analysis Centers (ISACs). These centers, two of which have already been established
for the financial and communications industries, are designed to allow companies targeted
by hackers or cybercriminals to share information in a secure semi-anonymous environment.
ISACs protect companies from having to disclose proprietary information when reporting
such incidents and also control the flow of publicity, so customers are informed but not
unnecessarily alarmed.
The problem with CERT/CC, ANSIR, ISACs, and
similar programs is that they are geared to peacetime operations, not to providing wartime
"indications and warning." Also, they do not routinely deal with military
commands. In other words, the most likely targets for an IW strike against the United
States are commercial computers and networks, and the first signs of an IW strike would
likely appear in the private sector. But the reporting network that commercial operators
are coming to rely on is focused mainly on pranks, crime, and natural disasters, not
well-prepared terrorist or military threats. In effect, the commercial sector--our canary
in the coal mine--is ill-prepared and disconnected from the organizations that would have
to respond to an attack on the United States.
The cultural divide
It would be easier to defend against IW threats
if government and industry could cooperate more effectively. Unfortunately, the two have
collided on several issues recently. These clashes have undermined the more highly
publicized efforts of the Clinton administration to promote public-private partnerships.
Some specific points of contention have included:
- Antitrust. Microsoft, Intel, and America
Online have all been the targets of antitrust suits or investigation by the Department of
Justice. True, computer and communications companies have long been targets of antitrust
suits; indeed, the IBM and AT&T cases were landmarks. But it is hard for government to
try to develop a close relationship with the new information companies with one hand,
while trying to break them up with the other.
- Encryption. The federal government tried
throughout the 1980s and most of the 1990s to regulate encryption technology. Law
enforcement and intelligence agencies feared losing their ability to intercept
communications. The information industry, however, believed that developing electronic
commerce was impossible without strong encryption.
- Criminal investigations. In July 2000, the
FBI became ensnared in a controversy when the press reported its use of
"Carnivore," a portable computer system for implementing court-ordered
intercepts of e-mail at Internet service providers (ISPs). Civil liberties groups
criticized the system as an invasion of privacy. The Clinton administration, which had
moved slowly on Internet privacy issues, was unprepared to explain either how the system
worked or how it intended to protect the rights of e-mail users and address the concerns
of ISPs.
- Immigration. Immigration laws have
prevented IT companies from hiring the foreign talent they believe they need. This has
increased their labor costs and threatened their competitiveness with foreign companies.
Such restrictions also conflicted with the New Economy zeitgeist of borderless markets.
Paradoxically, from the perspective of preparing
defenses against an IW strike, the government's position on all of these issues was
counterproductive. Americans would probably be safer from an IW attack if U.S. companies
dominated commercial markets for software and hardware, and such domination often requires
a monopoly. Antitrust litigation opens opportunities for foreign competitors. (How would
national security be affected if a foreign company designed the software used in U.S.
banks or in popular Internet browsers?) Similarly, although encryption cannot guarantee
that a commercial computer network is secure against an IW attack, it is probably
impossible to make a system secure without strong encryption. Finally, immigration
restrictions have encouraged U.S. companies to outsource software development to foreign
countries, where there is a greater chance that it will be compromised by foreign military
organizations and intelligence services.
Yet these disagreements run deeper than just
quibbles over policy details. The recent disputes reflect a clash of cultures. How did
this clash occur?
Part of the problem may simply be geography and
history. The first-generation computer companies such as IBM, Burrows, Sperry, NCR,
Control Data, and Digital were mainly based in the east and the midwest. So was AT&T,
which operated as a heavily regulated government-sanctioned monopoly until its breakup in
1984. Most of these companies had long histories as contractors to the Department of
Defense or other government agencies. As a result, they were accustomed to cooperating
with the government, even when "cooperation" really meant following
instructions. They also shared similar cultures. Many company officials had served in the
military or had at least worked closely with government agencies. There were also cultural
parallels: hierarchical organizations, formal rules, and even a uniform dress code at IBM.
The new companies that led the personal computer
and Internet revolutions--Intel, Apple, Netscape, Oracle, and, of course, Microsoft--were
different. Most took root on the west coast. Many corporate leaders had little experience
with government and had never served in the military, having been born too late to be
eligible for the Vietnam era draft (Bill Gates and Steve Jobs were born in 1955; Steve
Case in 1958; Marc Andreessen in 1973). The new leaders often learned computers on their
own and often rejected the usual course of formal education and earning professional
credentials. Gates and Jobs both left college early to concentrate on business; Andreessen
completed a normal stay at the University of Illinois, but once claimed he was not sure
whether he received a degree or not. Their model for success was the startup and the IPO,
not climbing the corporate ladder; and they believed that the consumer market was more
important than government sales. Generalizations are always risky: Andreessen, for
example, worked on Mosaic under government-funded research, and Larry Ellison created
Oracle partly with Air Force funding. But it seems fair to say that the new corporate
leaders lacked many of the government ties their predecessors had. Many see government,
along with high interest rates and tight-fisted investment bankers, as just another threat
that could put them out of business.
To make matters worse, the government has been
losing clout. It is no longer the most important customer for computers and often does not
have a lead in technology. For example, government officials could once boast that the
most capable supercomputers in the world resided at the government's nuclear labs and the
National Security Agency (NSA), where they were used to design hydrogen bombs and break
foreign codes. Today, however, the most powerful computers available are as often in the
private sector, being used, for example, by Boeing to generate three-dimensional designs
for airliners or by Pixar to create animated cartoons.
The government's diminishing influence has been
clear in its efforts to promote security standards for commercial information systems: a
key component of any defense against the IW threat. At one time, the National Institute of
Standards and Technology (NIST) could issue a standard such as the Data Encryption
Standard and assume that industry would adopt it because there was nothing better. By the
mid-1980s, though, some companies began offering encryption technology that approached or
surpassed that offered by the government and that would have been difficult or impossible
for government agencies to defeat. In 1994 the government tried and failed to convince
industry to adopt Clipper, an NSA-developed encryption system that would have given law
enforcement and intelligence organizations the means to break ciphers under certain
legally authorized conditions. Because it was no longer dependent on the government for
the best encryption and because its commercial interests seemed to diverge from the
government's efforts to restrict the technology, industry refused to go along.
Government authorities have had difficulty
adapting to the new situation. Even as the controversy over encryption and Clipper ensued,
NSA and NIST created the National Information Assurance Partnership (NIAP) in August 1997.
NIAP, a joint program to test and evaluate commercial security technology, works with
industry and with standard-setting agencies in other countries. Alas, figuring out how to
negotiate and facilitate, rather than impose, industry standards has put government
officials on new and unfamiliar ground. Officials are still trying to make the process
work, and representatives from industry have been slow to forget that its partners were
only recently opposed to any process in which they had a significant say about this key
component of information security.
To be sure, the information industry was not
blameless. Even as companies complained about government restrictions on encryption, most
software packages designed for consumers have been designed to be easy to use, not secure.
The automatic features that make popular programs easy to use also often make them easy to
hack. Similarly, although companies warned that government agencies threatened the privacy
of their customers for the sake of national security or law enforcement, industry often
had an even more cavalier attitude toward privacy. Witness the use of "cookies"
to monitor surfing habits on the World Wide Web, the selling of customer databases, and
often ambiguous self-policing privacy standards. And there is the immortal quotation of
Scott McNealy, chief operating officer of Sun Microsystems, who said when asked about
security features in a new network software product, "You have zero privacy anyway.
Get over it."
Taking steps
The Clinton administration's efforts during its
final year to smooth relations between government and industry will help prepare the
country against IW threats. Possibly the most important step was the administration's
January 2000 reversal on encryption restrictions that, for all practical purposes,
deregulated a key technology necessary for security against IW attack. Administration
officials also began to meet more often with representatives from industry. Even so, there
are several measures that the next administration should undertake that would further
close the gap between the commercial sector and the government and better prepare the
country for the IW threat.
The new administration must appoint officials
who are willing and able to establish a better relationship with the private sector. (Lt.
Gen. Michael Hayden, the current director of NSA, is an example.) Officials must
appreciate that global markets will usually defeat any efforts to limit technology.
Intelligence and law enforcement are always challenging tasks, and figuring out how to
gain access to an opponent's communications is simply part of the job. Government agencies
will probably lose any fight in which they try to maintain access to sources simply
through regulation. Besides, allowing industry to develop better information security
technology is not only essential to privacy and electronic commerce, it is essential to
protecting the country against IW attacks.
Another step would be to concentrate on
improving the private sector's understanding of the IW threat. It is impossible for any
government organization to identify and fix all the vulnerabilities that may exist in the
private sector's information systems. The infrastructure is too large, and there are too
many restrictions on proprietary data, intellectual property, and consumer privacy that
will limit the government's ability to act. Commercial software developers and network
operators need to build defenses into their own systems. They need to be aware that they
are the likely targets of attack, and they should have incentives to take precautions.
Education is key. Colleges should be encouraged to include IW as a topic in computer
science departments' curricula on information system security. Dorothy Denning, a
Georgetown University computer science professor, currently offers such a course, which is
a possible model. Some of the additional funding the Clinton administration proposed for
cybersecurity education could be used to develop such courses. Law enforcement, military,
and intelligence organizations might also make some of their personnel available to
support these courses.
Industry should expand its current efforts to
develop institutions that allow companies to share information about cyber attacks without
compromising their customers' privacy. But an additional step is required. Industry and
the Defense Department should establish operational links that will ensure that companies
can work with military commanders if they are targeted by an IW strike. These links would
be parallel to the existing reporting links to the NIPC, but would have a military, rather
than a law enforcement, approach. There should be a clearly defined cooperative procedure
that would allow military, defense, and industry representatives to reach a consensus on
which mode of operations is most appropriate in a given situation.
One practical difficulty in establishing these
links is that military commanders need precise, specific information that they can act on,
but almost all companies would have difficulty justifying the cost of the additional
people and facilities required to provide this information. There is also the
always-present problem of how a company can provide information to government authorities
without compromising its business interests or legal responsibilities. One approach might
be for military commands to assign active or reserve officers to CERTs and the ISACs now
being established. The officers would be responsible for generating the information the
military commands require and would be paid by the government, but they would operate
under the supervision of the civilian heads of these organizations. The relationship might
also be facilitated if the military personnel provided assistance to commercial
organizations in preparing their own security plans.
These links would be critical if the United
States found itself under a serious IW attack. Industry would need assistance in taking
defensive measures. During the summer of 2000, the U.S. Space Command was assigned
responsibility for coordinating information operations by U.S. military forces, so this is
where the most important connection between government and industry is required. It is
especially important to develop personal relationships at the working level between people
who will need to share information to respond to an attack. Exercises simulating an IW
attack would give military and industry personnel a better understanding of potential
threats and give them an opportunity to test and practice their response. Such exercises
would also give military personnel a better appreciation of industry's concerns, and
commercial operators a better appreciation of the military's concerns. Again, this is one
specific activity that the proposed funding for cybersecurity education could usefully
support.
The government should provide a combination of
carrots (such as subsidies) and sticks (such as liability statutes defining standard
accepted industry practices) to encourage commercial operators to take reasonable security
and privacy measures that would also protect against IW attack. For example, the level of
redundancy required to ensure that a commercial computer network, communications link, or
database is available during wartime may exceed the level of protection a company can
justify. The government could offer programs in which it would pay for this redundancy for
companies willing to participate.
Certain legislation could also help. For
example, some companies are reluctant to cooperate with government on cybersecurity issues
because they fear that even if officials protect their proprietary data in good faith,
they may be required to release the information to comply with disclosure statutes and
regulations. Some experts believe that once such information is in the possession of the
government, it might be subject to a Freedom of Information Act (FOIA) request. There is
some disagreement on this point, and there are already many exemptions protecting
information from FOIA requests. For example, technical information that companies create
under cooperative development projects with the government is exempt from FOIA, as is most
information that would compromise national security if released. But legislation would
make the exemptions required for cooperation on cybersecurity clear, and it is doubtful
that industry will participate without such ironclad guarantees. The Cyber Security
Information Act of 2000, introduced by Reps. Tom Davis (R-Va.) and Jim Moran (D-Va.) last
year, would provide these. Other legislation that would facilitate preparation against IW
threats would stipulate disclosure requirements. For example, financial institutions could
be required to report whether they meet industry standards for protecting their networks
and data. And most legislation aimed at protecting the privacy of consumers and other
users of the Internet would have the added benefit of improving security against IW.
Finally, all these institutions need to have
effective oversight mechanisms to ensure the privacy of consumers. Despite recent
controversies, government officials, civil liberties advocates, the information industry,
and the public all need to understand that they have common interests. A system that
ensures privacy is also more resistant to IW strikes and criminal attack. With a little
cooperation and foresight, everyone wins.
