My interest in researching the defensive posture of our infonnation infrastructure had its 
genesis in my experiences as a communications squadron commander, systems/database 
administrator, and director of technology in two Air Force organizations. While at the Air War 
College, this interest expanded to include strategic level implications and national preparedness 
to defend our country’s critical information resources. 

Ours is the most technologically dependent nation on earth—we cook in microwave ovens, 
use automated tellers, watch satellite television, get on-line and surf the Internet. Our 
burgeoning economy thrives on instantaneous, global electronic transactions. The military 
depends on space-based assets and precision-guided weaponry for battlefield victory. However, 
the aggregate affect of these many dependencies has created new, asymmetrical vulnerabilities 
that may some day be used against us. 

My objective in this paper is to critically examine America’s strategic level mechanisms to 
address and counter computer and network based threats to its national information 
infrastructure. It is my hope it will stimulate discussion, meaningful dialogue, and 
implementation of further corrective measures to defend this critical infrastructure. 

I would like to thank my Air War College faculty advisor, Colonel James Lee, for his 
encouragement, useful suggestions, and support throughout the course of this project. 



This research paper examines the strategic framework for defense of the National 
Information Infrastructure (Nil). Explored within the paper are the growing importance and 
dependency of the United States upon information technology and its associated infrastructure, 
possible threats to the information infrastructure, the implications of those threats, and currently 
employed defensive measures and their effectiveness. 

In addition, it provides five recommendations for improvements in the national strategic 
defensive posture: (1) establish a single agency for national information infrastructure defense, 
(2) establish a baseline regulatory environment, (3) employ core competencies of the DoD, (4) 
build bridges between Federal, state, and local governments, and (5) utilize DoD as national 


Chapter 1 

Ground Zero in Cyberspace 

Cyberspace is the battlefield of tomorrow ...instead of confronting us head-to- 
head on the traditional battlefield, adversaries will confront the U.S. at its point 
of least resistance— our information. 

—Sen. Fred Thompson 

Assault on the Information Infrastructure 

0200 hours, Day 1. Network operations centers on the east and west coasts of the United 
States are receiving a continual stream of inputs reporting their constituent mail servers are 
shutting down, from an apparent denial of service (DOS) attack. Similar activities are noted 
throughout the Federal sector at U.S. Government agencies nationwide. The DoD's Computer 
Emergency Response Team (CERT) monitoring capabilities report that military intrusion 
detection system (IDS) data indicates DoD firewalls and routers are experiencing millions of hits 
on a targeted port range, mail servers are rapidly becoming overtaxed, and grinding to a halt 
under the load. In an attempt to contain the outbreak, DoD’s Computer Network Operations 
(CNO) authorities direct all installations to electronically isolate themselves from the Internet. 

By 0800 hours, the impact is widespread and felt throughout the United States. Initial 
examination by computer scientists indicates the offender is a combination Internet “worm” and 
“virus,” exploiting a common scripting mechanism as the means of attack and propagation. 
Further, there are at least 15 reported variants of the worm—each possessing a common 


underlying software architecture, but displaying discernible distinctions in the precise 
mechanism of attack. Computer security experts believe this attack may be the result of an 
“adaptive,” or “polymorphic” virus. 1 

0900 hours, Day 1. The Internet worm is spreading rapidly and has affected commerce, 
inhibiting Wall Street economic data communications and electronic commerce transaction 
capabilities. By 1130 hours, operations are severely impacted on all networks accessing the 
various stock exchanges. By mid afternoon, major segments of the U.S. business and Federal 
sectors are effectively shut down. Computer security experts have now identified over 200 
variants of the worm, confirming it as the worst possible scenario to defend against—an 
ingeniously devised, maliciously inserted polymorphic wonn. In addition, during the night the 
MAE-East, MAE-Central, and MAE-West Internet switching nodes and the Internet domain 
naming system (DNS) experienced highly sophisticated electronic attacks and their 

communications throughput has been reduced to approximately 5% of normal 


levels—effectively grinding the Internet to a halt. 

0700 hours, Day 2. With mounting pressure from business, state, and Federal agencies, the 
President’s Critical Infrastructure Protection Board convenes an emergency meeting to discuss 
the growing crisis, and formulate a recommendation to the President for how the nation should 
respond. After their meeting, the recommendation is made that due to the severity, widespread 
effects, and escalatory nature of the attack, immediate measures must be taken to protect critical 
infrastructures and prevent further spread of the virus. 

Is such a scenario plausible? How widespread would the impact be to the nation? Which

system, greatly complicating eradication efforts. See for a 
more detailed explanation. 


Federal agency has the capability and mandate to lead the national response, and direct the 
actions required for its implementation? 

This paper will explore the answers to these questions, within the context of methodologies 
employed to defend the United States’ National Information Infrastructure (Nil). First, threats to 
the Nil will be examined, along with the implications posed by those threats. Next, the national 
policy relative to cyberspace security and the infonnation infrastructure, organizations with roles 
in its defense, and technological approaches for defending the infrastructure will be analyzed. 
These elements will be examined to detennine their effectiveness in providing an adequate 
national defensive posture. Finally, recommendations will be offered to buttress the overall 
national computer network defense strategy, to include an expanded role for the Department of

Threats to the National Information Infrastructure 

We cannot and must not make the mistake of assuming that terrorism is the only threat. 
The next threat we face may indeed be from terrorists, but it could also be cyber war, a 
traditional state-on-state conflict, or something entirely different. 

— Secretary of Defense Donald Rumsfeld 

Defining the Context 

Information and the infrastructure through which it traverses are ubiquitous in America, 

touching virtually every segment of national endeavor to some degree. This combined national 

information infrastructure facilitates commerce, education, government administration, national 

defense, recreation, and a multitude of other types of information exchange. Joint Pub 1-02 

defines this aggregate national infonnation infrastructure as: 

the nationwide interconnection of communications networks, computers, databases, and 
consumer electronics that make vast amounts of information available to users. The 
national information infrastructure encompasses a wide range of equipment, including 
cameras, scanners, keyboards, facsimile machines, computers, switches, compact disks, 
video and audio tape, cable, wire, satellites, fiber-optic transmission lines, networks of all 
types, televisions, monitors, printers, and much more. The friendly and adversary 
personnel who make decisions and handle the transmitted information constitute a critical 
component. 3 

3 Joint Publication 1-02,. Department of Defense Dictionary of Military and Associated Terms, 7 May 2002, 294. 


A closely related and associated term becoming increasingly familiar to most Americans is 
“cyberspace,” the notional environment in which digitized information is communicated over 
computer networks. 4 Cyberspace may be thought of as simply the medium through which 
information is conveyed via the information infrastructure from originator to recipient. 

The nation’s growing dependence on its infonnation infrastructure was highlighted by a 
2001 survey conducted by the U.S. Department of Commerce. The survey concluded that 143 
million Americans (about 54 percent of the population) use the Internet—an increase of 26 
million in 13 months. 45 percent of the on-line population uses electronic mail, and 39 percent 
of these on-line users make Internet purchases. These usage trends are likely to continue, as the 
number of Internet users is expanding at the rate of two million per month. 5 Information 
technology is equally entrenched in the American workplace, with 48 million Americans using 
Internet connected computers at work. 6 

Similar dependence exists within the national defense establishment. The DoD uses globally 
connected information systems and networks to support all aspects of military operations, and 
they comprise an essential element in enabling commanders to achieve information and decision 
superiority. In addition, these information systems, technology, and networks are integral 
elements in transforming the DoD to meet the anticipated demands of future warfare. 7 However, 
America’s increasing dependence on information technology and networked computers is a

7 Air Force Doctrine Document 2-5, Information Operations, defines information superiority as “that degree of 
dominance in the information domain which allows friendly forces the ability to collect, control, exploit, and 
defend information without effective opposition.” In addition, two of the six 2001 QDR goals relative to Defense 
Transformation are directly linked to the application of information technology. See Deputy Secretary of Defense 
Paul Wolfowitz’s Prepared Statement to the Senate Armed Services Committee Hearing On Military’ 


double-edged sword. Our dependence engenders the creation of accompanying vulnerabilities to 
a wide spectrum of threats that may seek to disrupt, deny, degrade, destroy or deceive critical 


in formation or information systems. 

Characterization of the Threat 

Threats to interconnected computer systems are continually evolving and increasing in 
sophistication, complexity and scope. The major threats identified in unclassified sources 
reviewed in this analysis include those posed by criminal groups, foreign intelligence services, 
hackers or hacktivists, virus writers, insider threats, and information warfare of state and non¬ 
state origin. 9 

Criminal threats are those threats perpetrated by criminals, primarily for the purpose of 
financial gain. In a broader sense, criminally oriented attacks against computer systems may 
encompass the full spectrum from fraud, scams, destructive attacks, identity theft, or theft of 
intellectual property. 10 Foreign intelligence services use Internet tools as part of their ongoing 
collection efforts, targeted in particular against open societies such as the United States where 
large amounts of information are readily available and sometimes afforded limited protection. 
Conversely, hackers pose an entirely different type of threat. Hackers probe and attack systems 
simply because they exist, and they possess the wherewithal to penetrate them. Hactivists are 
attackers who execute politically motivated attacks against public web sites or e-mail systems, to

National Infrastructure Protection Center expands these threats to include hactivists, in General Accounting Office,

promote their particular interests or agenda. Virus writers develop and maliciously introduce 

software via the Internet designed to destroy fdes, disrupt systems, or deny services to infected 

systems and networks. Viruses can cause extensive damage to infonnation in automated 

systems, and may have significant economic impact caused by lost productivity and actions 

required to repair infected systems. The impact of virus threats received world wide attention in 

2001, when the Code Red virus attack infected one million infected systems, creating an 

estimated $2.6 billion worldwide economic impact. * 11 However, insider threats constitute 

approximately 70% of all cyber attacks, and represent the threat posed by insiders—authorized 

users of computer systems who may strike at their employers through destruction, corruption of 

information, or theft of intellectual property. Finally, an emergent and significant threat is 

posed by the possibility of state and non-state actors waging offensive information warfare 

against U.S. systems or networks. In testimony before the U.S. Senate, George J. Tenet, Director 

of Central Intelligence, observed the significance of this threat: 

“.. .as this century progresses our country's security will depend more and more on the 
unimpeded and secure flow of information. Any foreign adversary that develops the ability 
to interrupt that flow or shut it down will have the potential to weaken us dramatically or 
even render us helpless.. .already, we see a number of countries expressing interest in 
information operations and information warfare as a means to counter U.S. military 
superiority. Several key states are aggressively working to develop their IW capabilities and

The spectrum of threats from these sources poses significant challenges to defending the 
National Information Infrastructure from attacks of both internal and external origin. In addition, 
successful penetrations and attacks against the infrastructure may have significant economic, 
operational, and national defense implications. 

Implications of Attacks 

Cybercrime is alive, well, and doing big business in America. The Computer Security 
Institute’s 2002 Computer Crime Survey reported 90 per cent of its corporate respondents 
experienced computer security breaches during that year. Eighty per cent of those breaches 
resulted in lost revenue, with aggregate dollar losses of $455,848,000. 14 Electronic attacks of 
this nature have the potential to not only cause significant initial impact from containment and 
eradication actions, but even greater potential downstream impact from second and third order 
effects resulting from the interruption of supply chains, business loss, and possible decline in 
stock prices. 15 

In contrast, threats posed by information warfare attacks against the military portion of the 
Internet, the Global Information Grid, and its interconnected systems, have potential to disrupt, 
deny, degrade, destroy or deceive information systems and networks, adversely impacting 
national defense. 16 The United States military is heavily dependent on technology-rich

Hill, 2001), 51-64. 

16 Air Force Doctrine Document 2-5, Information Operations, defines the Global Information Grid as “The globally 
interconnected, end-to-end set of information capabilities, associated processes, and personnel for collecting, 
processing, storing, disseminating, and managing information on demand to warfighters, policy makers, and support 
personnel. The GIG includes all owned and leased communications and computing systems and services, software 
(including applications), data security services, and associated services necessary to achieve information 


weaponry, most of which requires the collection, processing, and transmission of data in some 
form. Infonnation warfare directed against U.S. systems and networks would have the aim of 
denying infonnation needed for military operations. This type of warfare could encompass a 
variety of forms ranging from electronic warfare, psychological operations, deception 
techniques, offensive computer network attack, to physical destruction of U.S. command and 
control nodes. 17 In addition, as U.S. military doctrine espouses concepts of offensive 
information warfare, it is logical to assume our potential adversaries are incorporating similar 
concepts into their strategic, operational, and tactical war fighting doctrine. The asymmetrical 
possibilities inherent in information-based warfare have not escaped the Chinese, whose Army 
newspaper Jiefangjun Bio reported: 

After the Gulf War, when everyone was looking forward to eternal peace, a new military 

revolution emerged. This revolution is essentially a transformation from the mechanized 

warfare of the industrial age to the information warfare of the information age. Information 

warfare is a war of decisions and control, a war of knowledge, and a way of intellect. The 

aim of information warfare will be gradually changed from “preserving oneself and wiping 

out the enemy” to “preserving oneself and controlling the opponent..” Under today’s 

technological conditions, the “all conquering stratagems” of Sun Tzu more than two 

millennia ago—“vanquishing the enemy without fighting” and subduing the enemy by “soft 


strike” or “soft destruction”—could finally be truly realized. 

To counter these potential threats to the nation’s infonnation infrastructure, an extensive and 
growing policy, organizational, and technological framework exists. This framework constitutes 
the strategic foundation harnessing national resources in response to these threats.

Approaches for Defending the National Information Infrastructure

— John M. Deutsch, Director, CIA 

Strategic/National Level Framework 

The national policy and organizational framework for computer network defense has 
undergone virtually continuous evolution since the mid-90s. In addition, the tragic 9-11 attacks 
against the Pentagon and World Trade Center further crystallized interest in protecting critical 
infrastructures, spawning a surge of new legislation, organizations, and interest in supporting 
technologies. Understanding of the national strategic defensive framework requires an 
examination of the extensive mosaic of underlying policy. Table 1 provides a chronology of key 
policy instruments related to defense of the National Information Infrastructure. 

Executive Order 13010 began the process by establishing the President’s Commission on 
Critical Infrastructure Protection (PCCIP). The commission conducted its initial examination 
into the state of critical national infrastructures, to include the infonnation infrastructure, 
rendering an inaugural report in 1997. This report concluded America’s technology dependence 
rendered it vulnerable to cyber-threats, identified a “lack of awareness” within the government 


concerning the existence and severity of this threat, and concluded national defensive measures 

should be a cooperative effort between the public and private sectors. 19

In 1998, Presidential Decision Directive 63 established information infrastructure 
protection as a national goal, defining milestone dates for the year 2000 to achieve an initial 
operating capability, and 2003 for full protective capabilities. In addition, PDD 63 established 
two agencies integral to nationwide infrastructure defensive efforts, the Critical Infrastructure 
Protection Office (CIAO) in the Department of Commerce, and the National Infrastructure 
Protection Center (NIPC) within the Federal Bureau of Investigation. The former organization’s 

charter was to craft a national plan for infrastructure defense, while the latter focused on 


warning, assessment, law enforcement investigation, response, and reconstitution monitoring. 
Other significant tenets of PDD 63 were establishment of the National Infrastructure Assurance

Council to facilitate private and public sector cooperation, partitioning of the infrastructure into 
segments with lead responsible agencies, and a structure for information exchange on threats. 

Within this portioning plan, the DoD was established as the lead agency for the special function 


of national defense." 

In 2000 while the nation grappled with the Year 2000 (Y2K) computer problem, the White 
House released the next element of the national policy framework, the National Plan for 
Infrastructure Protection, which further focused Federal efforts, established additional 
milestones, required vulnerability assessments for each segment of the infrastructure, and made 

security a criteria for sustaining program funding In addition, this plan also directed the 


establishment of a national warning center for infrastructure attacks. 

Executive Order 13231, enacted in October 2001, established the President’s Critical 
Infrastructure Protection Board (PCIB), chaired by the Special Advisor to the President on 
Cyberspace Security. This board “coordinates cyber-related Federal efforts and programs,” with 
the assistance of ten supporting committees. An additional responsibility of the PCIB is 
coordination with the Office of Homeland Security on issues related to attacks against the U.S. 


information infrastructure." 

The latest and most significant evolution in the national policy for defending the infonnation 
infrastructure is the September 2002 draft National Strategy to Secure Cyberspace. This 
document serves as an overall strategy for synergistically integrating efforts of the previously 
mentioned initiatives. Its overall purpose is to provide:

an implementing strategy, which supports both the National Strategy for Homeland 
Security and the National Security Strategy of the United States. The National Strategy to 
Secure Cyberspace describes initiatives to secure U.S. infonnation systems against 
deliberate, malicious disruption and to foster an increased national resiliency. This strategy, 
together with the complimentary Homeland Security Physical Protection Strategy, provides 
the strategic foundation for the nation’s efforts to protect its infrastructures. 24 

Development of The National Strategy to Secure Cyberspace represents a collaborative 
effort between Federal and private sector lead agencies, and provides specific recommendations 
for each major infrastructure segment. In addition, two key themes of the strategy are: (1) the 
need for coordinated, voluntary partnerships among infrastructure segments to defend the 
information infrastructure, and (2) strengthening Federal information security to make it a model 


for other infrastructure segments. 

This extensive body of policy and organizations provides a basic structure for management 
and defense of the national information infrastructure. Similarly, the underlying technological 
framework provides the flesh and blood giving our national defensive capability its substance. 

Computer Network Defense Supporting Technology 

The technological foundation supporting the defense of the information infrastructure is 
comprised of a complex array of physical, electronic, software, and procedural elements. While 
a detailed discussion of the technological underpinning of computer and network security is 
beyond the scope of this paper, the elements most commonly used in both the private and public 
sectors will be briefly examined. 

Physical defensive measures include those actions taken to prevent unauthorized users from 
obtaining physical access to computer equipment and networks. These measures also include the 

24 The President’s Critical Infrastructure Protection Board, The National Strategy’ to Secure Cyberspace, Draft, 
September 2002 (Washington, D.C., The President’s Critical Infrastructure Protection Board, 2002), 1. 


use of passwords for authorized users to gain access, along with newer, emergent technologies 

such as biometrics, which may include handwriting, voiceprints, face recognition, or fingerprints 


to identify authorized users." 

Electronic measures include the use of firewalls, which function as electronic barriers 
between local area computer networks and the Internet. Another widely employed electronic 
measure is the virtual private network (VPN), a secure connection over a public network. 
Serving to provide continuous electronic surveillance over a network, intrusion detection systems 
(IDS) serve as burglar alarms, monitoring networks to detect potential attacks. Combined with 
vulnerability scanners, which provide a self-help tool to detect vulnerabilities, these two 
capabilities are employed by virtually all major private sector enterprises and DoD installations 


as key elements of their defensive posture." 

Software defensive measures include security features built into the design of operating 
systems such as Microsoft Windows, and applications software providing security functionality 
such as anti-viral software. However, a significant number of vulnerabilities are created by 
software design defects. The industry average software development error rate is typically five 
to fifteen errors, or “bugs,” for each thousand lines of computer code written." Each of these 
errors is a potential security risk that may be exploited. To prevent exploitation of these 
vulnerabilities, software manufacturers release updates, patches, or service packs, which

Sons, Inc., 2000), 141-143. 

27 Ibid., 188-197. 

28 Ibid., 210. Industry standard software production is typically characterized by error rates in this range. In Code 
Complete" by Steve McConnell (Microsoft Press, 1993), the noted industry average for code production is 8-20 lines 
of correct code per day. In addition, it notes that industry average experience suggests that there are 15-50 errors per 
1000 lines of delivered code. The security implications are significant. The continuous stream of warnings and 
updates from major vendors such as Microsoft highlight the severity of this problem. 


normally require manual installation by systems support personnel. Installation of these patches 


represents a significant expenditure of time and effort to sustain adequate security." 

Finally, procedural elements such as local security policies, and user training and awareness 
programs, are important parts of the overall defensive framework. Security policies address the 
organizational rules of engagement for computer and network security and proper use of these 
systems. These programs are essential, as even the best policies and supporting technological 
tools are of marginal value unless coupled with effective training programs. 

29 Typically, installation of software patches when configuring a new system requires several days effort by a fully 
qualified network technician. My experience has been that installation of recurrent patches after a new system is in 
operation may take from minutes to several hours, depending on its complexity and if problems are encountered 
during the installation. 


Chapter 4 

Effectiveness of National Information Infrastructure Defensive 


Our challenge in this new century is a difficult one. It’s really to prepare to defend 
our nation against the unknown, the uncertain and what we have to understand 
will be the unexpected. That may seem on the face of it an impossible task, but it 
is not. But to accomplish it, we have to put aside the comfortable ways of thinking 
and planning, take risks and try new things so that we can prepare our forces to 
deter and defeat adversaries that have not yet emerged to challenges. 

—Secretary of Defense Donald Rumsfeld 

Thus far, key policy, organizational, and technological components employed to defend the 
national information infrastructure have been examined. In this section, the effectiveness of these 
elements will be scrutinized to assess their adequacy in providing adequate defense of the 
information infrastructure. 

Evaluation Criteria 

The metrics used to establish benchmarks to assess the effectiveness of computer network 
defense measures are: (1) recent findings from investigations conducted by the United States 
General Accounting Office (GAO), (2) network incident data collected and reported by the 
Carnegie-Mellon University Computer Emergency Response Team (CERT), Coordination 
Center, (3) field interviews and discussions conducted as part of the research for this paper, and 
(4) the personal experiences of the author as an Air Force communications squadron commander, 
systems/database administrator, and organizational director of technology. 


GAO Audit Findings 

GAO-02-96 IT, Critical infrastructure protection: Significant Challenges Need to be 
Addressed ,” July 2002, provides a comprehensive assessment of the overall state of the nation’s 
ability to protect its critical infrastructures. This report summarized previous GAO efforts 
pertinent to infrastructure security, identifying four major areas requiring improvement: (1) the 
lack of a national cyber and physical critical infrastructure protection strategy, (2) the need for 
improved analysis and warning capabilities, (3) the need for improved infonnation sharing 
within the Federal government, and between the Federal government, private sector, state and 


local governments, and (4) persistent pervasive weaknesses in Federal computer systems. 

1. Lack of a national cyber and physical critical infrastructure protection strategy. Due in 

large part to the events of 9-11 significantly elevating national awareness of vulnerabilities to our 
critical infrastructures, some progress has been made in this area since the GAO audit. As 
aforementioned, the National Strategy to Secure Cyberspace, serving as an overarching strategy 
for information infrastructure protection efforts, was released for public comment on 19 
September 2002. 

However, the GAO did not address one of the most pronounced shortcomings of the 
strategy. Although the document will no doubt meet the letter of the law in providing a national 
strategy, it unfortunately suffers from the notable deficiency of being a “paper tiger,” lacking any 
statute authority to direct implementation of its numerous recommendations. 

30 United States General Accounting Office,, Critical infrastructure protection: Significant Challenges Need to be 
Addressed (Washington, D.C.: United States General Accounting Office, 2002), 2-3. This report summarized 
previous GAO work in this area, to include a similar GAO effort published in , Critical infrastructure protection: 
Federal Efforts Require a More Coordinated and Comprehensive Approach for Protecting Information Systems, 
July 2002. 


This unfortunate result directly stems from PDD 63 itself, which calls for only 
coordinating authority, and encouraged participation, by private sector infrastructure segments. 
While these are worthwhile goals, it is unclear if private sector infrastructure segments will 
voluntarily submit to its recommendations for securing their networks and systems if a 
substantial expenditure of resources is required. However, our increasing vulnerability points 
to the need for a more structured management approach. The overall effectives of the national 
strategy would be enhanced by some degree of underlying mandated compliance, combined with 
a program of private sector compliance incentives, to ensure minimum standards for nation-wide 
security are achieved. 

2. Need for improved analysis and warning capabilities. Similarly, The National 
Infrastructure Protection Center, operated by the FBI, was chartered under PDD 63 as the 
nation’s nerve center for warning and assessment for infrastructure protection, and is empowered 
to issue warnings and guidance to owners and operators of critical infrastructure components. 
However, that organization’s effectiveness has been hampered by the lack of an analytic 
framework with which to assess strategic infrastructure attacks, personnel shortages, and limited 

T 1 

nation wide understanding of its intended purpose/ 

Once again, the GAO described the symptom but only partially identified the underlying 
cause. The lack of statute authority to direct actions be taken in response to significant threats is 
a key deficiency in establishing a viable national defense structure. The absence of an 
underlying statutory standards framework for key infrastructure components is a substantial 
deficiency, which must be resolved. 

31 United States General Accounting Office, Critical infrastructure protection: Significant Challenges Need to be 
Addressed (Washington, D.C.: United States General Accounting Office, 2002), 22. 


3. Need for improved information sharing. The GAO also observed that additional emphasis 
is needed to enhance sharing of information between and among Federal and private sector 
organizations. This issue has historically been problematic, as commercial enterprises are often 
reluctant to admit that they have experienced a network penetration or attack. While the FBI has 
expanded its capabilities to detect and respond to infrastructure attacks, particularly those with 
suspected criminal intent, their efforts will be of limited value without an open and unrestricted 
in formation flow from the private sector. Although additional dialogue is needed, mechanisms 
must be established promoting the free flow of information, while addressing private sector 
concerns for reporting anonymity. 

4. Persistent pervasive weaknesses in Federal computer systems. GAO auditors identified 
the need for improvements and an overall strategy to resolve security weaknesses in Federal 
computer systems. The GAO viewed a central aspect of this problem as the lack of an 
overarching security strategy within the Federal government, coupled with often-unclear roles 
and responsibilities. As discussed earlier, the National Strategy to Secure Cyberspace provides 
at least an initial starting point for an integrative Federal strategy, but must be coupled with 
corresponding security programs within each agency to resolve their respective deficiencies. 

Other issues. The GAO also observed that while approximately 50 organizations exist with 
roles in critical infrastructure protection, not all critical infrastructures were represented by these 

32 “FBI Seeks Help vs. Cyber Crime,” Federal Computer Week, 1 November 2002, on-line, Internet, available from 1-01-02,asp, accessed 2 November 2002. 

33 United States General Accounting Office, Critical infrastructure protection: Significant Challenges Need to be 
Addressed (Washington, D.C.: United States General Accounting Office, 2002), 3. 


organizations, and the roles of the various agencies are not widely understood. 34 However, the 
GAO again stopped short of identifying a critically important aspect for strategic defense of the 
in formation infrastructure—unity of command. While there are many agencies involved in 
infrastructure protection, there is no single agency with the mandate to act authoritatively and 
decisively in the event of a significant crisis or attack on the national information infrastructure. 
Presidential Decision Directive 63 tasks the National Coordinator for Security, Infrastructure 
Protection and Counter-Terrorism, who reports to the President through the Assistant to the 
President for National Security Affairs, with overall PDD 63 implementation, but specifically 


states this individual “will not direct Departments and Agencies.” To resolve these 
deficiencies, a single Federal agency should be designated with the charter and tools for 
providing strategic direction to the national infrastructure defensive effort, to include prevention, 
detection, characterization, and response to assaults. 

Network Incident Data 

In addition to deficiencies that must be resolved in the current national policy and 
organizational structures, existing infrastructure defensive strategies, as measured by the 
incidence of reported attacks, are ineffective and require significant improvement. Figure 1 
summarizes incidents reported to the CERT during the years 1997 through the third quarter of 
2002 .

□ Incidents 

Figure 1 CERT Incident Data, 1997-2002 

As depicted in Figure 1, the number of reported network incidents has increased 
exponentially since 1997 when the inaugural national initiatives in information infrastructure 
protection were begun. In addition, the CERT estimates that up to 80 percent of all incidents go 
unreported. In spite of increased awareness, widespread availability of threat information, a 
substantial number of organizations involved in promulgating infrastructure security information, 
and technical means to mitigate the impact of most threats, these collective measures have not 
produced a corresponding decline in incidents. The reasons for this situation are twofold. First, 
there are simply more information systems, networks, and vulnerabilities to contend with each 
year. Second, in the absence of statutes mandating their implementation, available protective 
measures are not universally employed. The Business Software Alliance’s July 2002 survey of 
in formation technology professionals indicated even common tools, such as anti-viral software 
and password changes, were not universally used and security updates were not regularly 
made. 37

37 “U.S. Business Cyber Security Survey”, conducted by the Business Software Alliance, 24 July 2002, 14. 


Finally, even though the events of 9-11 raised awareness and resulted in some infrastructure 
security improvements in the U.S., this trend has been far from universal. An August 2002 survey of 500 corporate security and IT personnel reported more than half of 
the surveyed organizations have seen no improvement in their organization’s security posture 
since the attacks of 9-11. 38 Although the trend is better in the Federal sector, with 71% of 
Federal agencies reporting improved security, 29% indicated no significant improvements had 


occurred in their agencies since 9-11. 

Field Interviews and Discussions 

During my research for this paper, I also had the pleasure of discussing views on protection 
of the national information infrastructure with several private sector and Federal subject matter 
experts. One of these experts was Mr. Steve Goldsby, CEO of Integrated Computer Solutions, 
Inc., a Certified Information Systems Security Professional (CISSP) who draws upon an 
extensive information security background in both the Federal and private sectors. 40 He 
observed that substantial increases in an organization’s information security posture are typically 
achieved through an iterative process whereby an organization’s security status is assessed, and 
basic technological elements such as firewalls, intrusion detection systems, anti-viral software, 
and security policies are implemented. 

Further, Mr. Goldsby believes that a greater degree of synergy and leveraging of strengths of 
both the private sector and public sector can be achieved. One of the private sector’s key

strengths, according to Mr. Goldsby, is “the ability to deliver tailored solutions quickly” to meet 
the infonnation security needs of organizations. He observes that the most promising method by 
which the Federal government can stimulate private sector development and deployment of 
enhanced security technologies needed to buttress infonnation infrastructure defense is through 
more Federal grants for basic research. 41 Both of these areas are promising and have significant 
potential for improving overall infrastructure security, could be integrated into an overall public- 
private sector partnership program, and should be the subject of further research. 

In addition, during the development of this paper, my research period for this project 
coincided with the 25-29 August 2002 Air Force Information Technology Conference, held at 
the Montgomery Civic Center, in Montgomery, Alabama. At this event, representatives from 
many of the nation’s premier information security technology providers were on-site exhibiting 
the latest in information security technologies. Virtually all of these vendors offered off-the- 
shelf security solutions comprised of variants of the basic technological building blocks that have 
been discussed earlier in this paper. Consequently, organizations desiring to design a defensive 
strategy enhancing their security posture have a wealth of private sector resources to draw upon. 

Personal Experiences 

Based on over two and a half decades of practical experience in information technology, 
coupled with analysis of available data compiled during research for this project, my assessment 
is that the overall state of national information infrastructure security, although marginally 
improved during the last decade and showing increased emphasis since 9-11, requires additional 
systematic attention to afford adequate protection to this critical national resource. In this regard, 
while the GAO recommendations discussed earlier did not go far enough in some areas, their 

41 Mr. Stephen Goldsby, CEO, Integrated Computer Solutions, interviewed by author, 30 August 2002. 


overall observations correctly captured the most significant issues adversely affecting 
infrastructure defense. 

From my direct observations and experience of the Air Force computer network operations 
environment, the most significant problems which must be resolved those of: (1) “human 
capital,” e.g. sustaining and equipping an adequately trained computer operations technical force, 
and (2) disciplined, systematic utilization of available technological tools. 

First, military manpower shortages and increasing military operations tempo create 
significant challenges for understaffed network operations centers to sustain day-to-day 
operations. Additional research is needed to detennine possible solutions to this problem, e.g. 
bonuses, incentives, privatization, etc. 

Second, Air Force organizations for the most part have the basic technical tools needed to 
secure the military’s portion of the national infonnation infrastructure. Unfortunately, the areas 
not addressed by these tools continue to create problems. An area where this is particularly 
problematic is that of security update/patch management. And while some installations have 
partially automated this process, and GSA contract vehicles for patch management are now 


available, more adaptive, less manpower intensive automated tools are needed. 

Overall, although implementing legislation and organizations have been inexistence since 
1997, and most of the required technical means are available to design a satisfactory defensive 
architecture, additional emphasis is needed in both the private and Federal sectors to elevate 
national infonnation infrastructure defense to the level it warrants.

Chapter 5 


America is successful because of the hard work, creativity, and enterprise of our people 

— President George W. Bush 

While our nation has begun the journey to secure its critical infrastructures, we have not yet 
reached the destination. In view of the significant changes occurring throughout the Federal 
government since 9-11 to buttress infrastructure security of all types, we are at a key juncture to 
implement additional improvements building upon those already taken. The recent creation of 
the cabinet level Department of Homeland Security holds great promise to simplify the 
consolidation, streamlining, and simplifying of the national structure for critical infrastructure 
defense against both physical and electronic attack. In addition, a tremendous potential for 
private and public sector synergism exists, which if exploited could result in significant 
improvements in the nation’s infrastructure defense. To implement these improvements, five 
recommendations are suggested, expanding upon and providing solutions to the problems framed 
by the GAO—resolving structural, indications/waming, infonnation sharing, and overall 
systemic security deficiencies. 


Recommendation 1: Establish a single agency for information infrastructure 


Changes are required to the current organizational framework for protection of the 
national infonnation infrastructure. As addressed earlier, there are currently 50 organizations 
with roles in infrastructure protection, and broad agreement exists that a central entity is needed 
to achieve unity of effort. 4 ' No evidence was found that any single agency has the statute 
authority to direct the scope of actions that would be required to mount the defense to a strategic 
assault on the infonnation infrastructure. 44 This would cause confusion, delay, and unpredictable 
outcomes in the event of a scenario such as this treatise posited in its opening paragraphs. In 
light of its role in protecting the nation, a logical candidate for this function would be the new 
Department of Homeland Security. Designation of this agency for this role would consolidate 
response actions for infrastructure protection within one agency, engender unity of action in the 
event rapid response is needed to react to strategic level events, and provide one universally 
recognized governmental organization for private sector interface and coordination. 

Recommendation 2: Establish a baseline regulatory environment 

Thus far, the Internet has largely been unregulated, decentralized, and relatively 
unconstrained by government intervention or regulation. However, the increasing inability to 
prevent, contain, and adequately respond to information infrastructure threats and vulnerabilities 
warrants more scrutiny, and at least minimal implementation of nationwide guidelines. 
Improvement is needed in two major areas: (1) the provision of a common set of computer and 

43 Anthony H. Cordesman, Cyber-Threats, Information Warfare, and Critical Infrastructure Protection: Defending 
the U.S. Homeland (Westport, CT.: Praeger Publishers., 2002), 171. 


network security standards applicable to all segments of the national infrastructure, and (2) 
guidelines specifying minimum security requirements for core internet service providers. 

Currently, there are multiple sources of standards that organizations desiring to enhance 
their security posture may consult to obtain guidance. Some have their origins in the Federal 
government; others from a variety of private sector security organizations. An initiative 
promising to provide a set of common standards, NIST Special Publication 800-37, “Guidelines 
for the Security Certification and Accreditation of Federal Information Technology Systems,” 
was released 28 October 2002, under the auspices of the National Information Assurance 
Partnership (NIAP). The NIAP is joint effort of the National Institute of Standards and 
Technology (NIST) and the National Security Agency (NSA) to meet the security testing, 
evaluation, and assessment needs of both information technology producers and consumers. The 
goal of the project is to provide a clear, step-by-step roadmap for agencies to develop and 
implement enterprise security programs and certification processes. 45 These standards should be 
evaluated for possible mandated use not only within the Federal government, but also as required 
performance standards for agencies desiring to transact business with government agencies. 

There are currently over 4,000 active Internet service providers and over 165,000 Internet 
points of presence registered in the U.S. and Canada, forming the bulk of the domestic 
in formation infrastructure. 46 These Internet service providers operate under varying, self- 
regulated degrees of security, and require some measure of foundational security standards to 
guard the overall integrity of the domestic backbone network. The reasons for this are twofold: 

44 This fact was bom out not only by examination of all relevant documentation, as delineated within this paper, but 
by supplemental discussion with security personnel at the NIPC, the Air Force Intelligence Agency, and private 
sector security firms contacted during this project. 

45 “NIST-NSA Team Readies Systems Security Guidance,” Government Computer News, on-line, Internet, available 
from nol/daily-updates/20220-l.html , accessed 12 October 2002. The draft guidance is 
available on-line, Internet, at 


first, it is unlikely that each of the 143 million private citizens connected to the Internet can or 
will implement appropriate security controls (firewalls, anti-viral software, security patches, etc) 
on their home PCs. However, proper firewalls, anti-viral software, filters, and intrusion 
detection devices at ISPs could significantly reduce the promulgation of viruses and other threats 
throughout the Internet, and should be mandated. 

Additionally, during the course of research for this paper, the most pervasive denial of 
service attack against the Internet to date was launched against the domain name server (DNS) 
infrastructure. The DNS architecture translates Internet plain text addresses, such as , into Internet protocol addresses such as, for routing and 
delivery of messages across the Internet. The attack flooded all 13 servers in the worldwide 
network, and was reportedly launched from servers in the U.S. and Korea. 47 Due to the potential 
widespread disruption from this type of attack, the DNS infrastructure should also be examined 
for possible hardening, additional redundancy, and included within the regulatory umbrella 
suggested for ISPs. 

A workable and mutually beneficial model adaptable to information infrastructure 
security is found in the U.S. Environmental Protection Agency’s (EPA) “Partners for the 
Environment Program.” In this program, existing environmental law is enforced, but 
participation in this voluntary program benefits private sector participants via cost savings, 
increased profits, improved access to technical assistance, and provision of a framework for

improving environmental performance. Both private and public sectors benefit through better 


overall environmental compliance, energy savings, and awareness. 

Implementation of a similar partnership program for information infrastructure security 
would have similar benefits and achieve the objectives delineated in the National Strategy to 
Secure Cyberspace. While it is recognized there are concerns over Internet privacy issues and 
increased governmental control that must be addressed, a basic foundation of standards is 
essential to raising the overall level of security within the information infrastructure. Additional 
study is needed to address these issues, devise an optimum structure for public-private 
interaction, and determine the type of incentives that should be employed. 

Recommendation 3: Utilize Core Competencies of the DoD 

In consonance with the tenets of The National Strategy to Secure Cyberspace’s theme of 
increased information sharing between the Federal and private sectors, great potential for 
synergism exists. DoD has long recognized the importance of protecting its systems, and the 
essential need to sustain an uninterrupted information flow to accomplish its national defense 
mission. Joint Vision 2020, encapsulating future joint war fighting doctrine, defines this concept 
as information superiority, “the capability to collect, process, and disseminate an uninterrupted 
flow of information while denying an adversary’s ability to do the same.” 49 In this regard, 
networks provide military forces the ability to shape the battlespace, command, and control 
assigned forces. Based on DoD’s extensive experience, four areas of competency appear 
especially promising for export to other infrastructure segment protection initiatives: (1) 

48 “Partners in the Environment,” United States Environmental Protection Agency, on-line, Internet, available from , accessed 6 November 2002. 

49 Joint Vision 2020, 8. 


indications and warning architecture, (2) hierarchical network management, (3) enterprise 
security and information assurance program management, and (4) the use of exercises. 

Indications and warning architecture 

First, DoD’s ubiquitous indications and warning architecture is an important resource that 
should be leveraged by the Department of Homeland Security, and other infrastructure defense 
agencies, to provide strategic early warning. For example, in 1998 the Department of the Air 
Force deployed network management capabilities and base infonnation protection tools at 109 
bases. These capabilities included firewalls, scanning tools, and network management tools at 
main operating bases. This architecture was expanded in 2000 to include intrusion detection 
systems to provide indications and warning. These aggregate capabilities fonned a highly 
effective Air Force enterprise security system—capturing on its sensor grid over 315 million 
suspicious connection attempts during the year 2000. This successful defensive capability 
allowed only one unauthorized connection by an outsider for every 20 million suspicious 
connection attempts. 50 This architecture has proven highly effective in detecting attempted 
network penetrations, and should be employed both as a data source in a centralized national 
control and monitoring scheme, and also as a model for other infrastructure segments. 
Hierarchical network management 

The National Strategy to Secure Cyberspace recommends the creation of a national 
cyberspace network operations center, to provide early detection, prediction and response to 
attacks on the information infrastructure. 51 This concept should be pursued, and modeled on the 
experience of the network operations hierarchy successfully employed by the DoD. The DoD’s

hierarchical network management structure is depicted in Figure 2. At the apex, the Defense 
Infonnation Systems Agency’s (DISA) Global Operations Support Center is responsible for 
overall worldwide enterprise management of DoD’s portion of the national information 
infrastructure. Aiding in overall management are regional centers located in the CONUS, 
Pacific, and European theaters. The final tier consists of network control centers at each 
installation, which provide local operations and information assurance support. Information 
flows from local network control centers and regional operations centers to the global operations 
center, which provides overall network management oversight of the DII. The success of the 
system stems from a continual flow of information regarding the overall performance, status, and 
threat environment of the global network. 


Military Services 


Figure 2 DoD Network Management Structure 

A similar concept could be employed to manage the national information infrastructure. 
Figure 3 provides a notional view of how such a nation wide indications, warning, and response 
architecture might be developed. Implementation would employ a national operations center, 


controlled by the Department of Homeland Security and operated by one of its agencies. This 
national center would be equipped with the required data feeds from indications and warning 
capabilities, receiving these inputs from subordinate level regional operations centers, or directly 
from individual ISPs, domain name server organizations, and major internet backbone providers. 
A key benefit of this architecture would be development of a capability to receive, characterize, 
and disseminate response actions rapidly throughout the national infrastructure. 




Figure 3 Notional National Cyberspace Management Structure 
Enterprise security and information assurance program management 

DoD has extensive organizational infonnation and computer security programs implemented 
at all levels throughout its structure. These programs address all aspects of computer security, 
from definition of organizational security policies, assessment, accreditation and certification of 
systems, to comprehensive user training. It is likely many of these programs could in part or 
total be exported to other segments of the infrastructure for their use in developing enterprise 
information security programs. 

The use of Exercises 


Finally, the use of exercises should be increased to provide a realistic environment within 
which to evaluate and plan responses to possible attacks on the information infrastructure. 
Exercises were heavily employed during national preparation for the Y2K computer event, and 
provide valuable experience in remediation, recovery and contingency planning. A pioneer 
effort, which could serve as a nationwide model, is the joint city, private sector, and Air 
Intelligence Agency “Operation Dark Screen” exercise planned by the Center for Infrastructure 
Assurance and Security at the University of Texas, San Antonio, Texas. Dark Screen is a three- 
phase exercise designed to help participants better understand how to prepare for, recover from 
and protect a city's critical infrastructure in case of a cyber attack. As national mentors, DoD 
organizations should foster and increase their participation in such combined exercises with state 
and local governments. 

Recommendation 4: Build bridges between Federal, State, and Local 


The National Strategy to Secure Cyberspace stresses the importance of increased 
communication and coordination between local, state, and Federal governments. The need for 
this strategy is due to: increasing dependence on integrated systems, State, local, and Federal agencies 
have to collectively combat cyber attacks. Sharing information to protect systems is an 
important foundation for ensuring government continuity...States are exploring options 
for improving information sharing both internally and externally. These options include 
enacting legislation that provides additional funding and training for cybersecurity and 
forming partnerships across State, local, and Federal governments to manage cyber 
threats. 53 

52 “CIAS Prepares for Operation Dark Screen,” University of Texas San Antonio, on-line, Internet, available from stories/2002/Aug02/cias.htm , accessed 14 October 2002. 

53 The President’s Critical Infrastructure Protection Board, The National Strategy to Secure Cyberspace, Draft, 
September 2002 (Washington, D.C., The President’s Critical Infrastructure Protection Board, 2002), 31. 


While state governments in general have initiated efforts toward systems security and may 
use existing Federal linkages for this purpose, it is likely that local governments will require 
some degree of mentoring and assistance to raise their level of security. Although rudimentary 
means exist for the sharing of information infrastructure threats, such as Information Sharing and 
Analysis Centers (ISACs), and web sites such as the Infraguard site (, more 
effective methods are available. 54 

An excellent example upon which to employ DoD mentorship and coordination with local 
municipalities is the Year 2000 Preparation Model. Preparation for the year 2000 computer 
event was unprecedented in the history of information technology, both in America and 
throughout the world. Planning efforts for preparing America and its information systems for the 
Year 2000, or Y2K, affected every segment of the national infrastructure. Germane for purposes 
of this discussion are the numerous DoD-local partnerships that were created to address Y2K 
related issues throughout the country. The author’s experiences in this regard as the installation 
project officer at Altus Air Force Base, Oklahoma were both challenging and rewarding. 
Working with the local municipality, every aspect of planning for the Y2K issue, to include 
“worst-case,” “what if’ scenarios, was conducted. In each case, local officials were more than 
willing to both accept recommendations, and dialogue with the DoD, regarding solutions for 
addressing contingency scenarios. Drawing upon these type partnerships that were established 
throughout the U.S. could serve as an excellent starting point for DoD mentorship in 
infrastructure security, and could expand to include other critical infrastructure sectors such as 
water, electric power, transportation, and public health services. Such efforts would have the

of threat information by infrastructure lead agencies. 


dual benefit of bolstering the defensive posture of key national infrastructures, as well as 
strengthening relations between the DoD and local governments for the common good. 

Recommendation 5: Utilize DoD as National Mentor 

One of the central tenets of The National Strategy to Secure Cyberspace is that of creating 
an infrastructure security environment in which the Federal government serves as the model for 
other segments of the infrastructure. Although DoD’s current engagement and deployment of its 
resources in the global war against terrorism could limit its capabilities, its long experience with 
securing critical information and infrastructures ideally equips it to serve as a national guide, or 
mentor. It is envisioned the DoD could serve in this capacity through liaison with the 
Department of Homeland Security, until that organization is fully implemented and capable of 
leading the national defensive effort. 

Nationally, we are at a critical juncture in light of 9-11. While terrorists are currently not 
employing cyberspace methods to attack the U.S, the potential asyimnetrical advantage such 
attacks would afford cannot be discounted. Implementing improvements in the national policy 
structure, creating a baseline regulatory environment, leveraging DoD’s extensive experience, 
and building bridges to other infrastructure segments and governments with overall DoD 
mentorship, promises to point America in the right direction to accomplish the goals of The 
National Strategy to Secure Cyberspace. 

Perhaps a fitting culmination of this paper is writing the final chapter to its opening scenario. 
If the recommendations posited in this examination stimulate discussion leading to 
improvements in the nation’s ability to defend its infonnation infrastructure, it is likely the 
ending to this fictional scenario would be recorded in this manner: 


1600 hours, Day 1. The nation quickly returned to nonnal after countering the potential 
threat from the recent attack launched against its information infrastructure. Stemming from 
substantial improvements to America’s capability to defend its critical infrastructures incident to 
the establishment of the Department of Homeland Security, the National Cyberspace Operations 
Center (NCOC), baseline security standards, and enhanced national indications and warning 
structure, a joint Federal-private sector response team quickly formulated a defense rendering the 
polymorphic “super” virus ineffective. Using the nationwide link from the NCOC to ISPs and 
Internet carriers, the fix was rapidly disseminated and the threat contained before any significant 
damage could occur. The President expressed his appreciation to the Special Advisor for 
Cyberspace Security, the Departments of Defense and Homeland Security, and all members of 
the infrastructure protection team for the success of the effort. 

In conclusion, America has been given a rare opportunity in modern warfare—the chance to 
prepare itself for an asymmetrical assault certain to come on an as of yet unknown electronic 
battlefield. With an effective national strategy, coupled with synergistic public and private 
sector effort, we will transform ourselves to achieve these objectives—simultaneously ensuring 
America is ready for the challenges of 21 st century information-realm warfare.
