Created in the wake of the September 11, 2001, terrorist attacks, the Department of Homeland Security came into being with the daunting core mission of taking action to protect the
nation from terrorist attack and the simultaneous requirement to continue to perform the
numerous other critical functions of all its component agencies. The complexity of the departmentâ€™s mission was further compounded by the fact that it depended not only on the success of
the departmentâ€™s component agencies, but also on the efforts of a national homeland-security
enterprise comprised of organizations at the federal, state, and local level, both inside and outside government. That there have been challenges in carrying out this endeavor in the years
since should surprise no one. However, it has also been the fortunate reality that, whatever
those challenges, at the time of this writing, there have been no major terrorist attacks within
the United States since 9/11.
This paper is one of a series of short papers resulting from a research effort initiated by the
RAND Corporation during the transition in presidential administrations in 2008â€“2009. As
the first change in administration since the creation of the Department of Homeland Security,
this period represented an opportunity to reexamine and revisit the goals of homeland security
policy and assess how we as a nation are trying to achieve them, ask whether what we are doing
is working, and make adjustments where necessary. The goal of RANDâ€™s research effort was
not to comprehensively cover homeland security writ large, but rather to focus on a small set
of policy areas, produce essays exploring different approaches to various policy problems, and
frame key questions that need to be answered if homeland security policy is to be improved
going forward. The results of this effort were diverse, ranging from thought experiments about
ways to reframe individual policy problems to more wide-ranging examinations of broader
policy regimes. These discussions should be of interest to homeland security policymakers at
the federal, state, and local levels and to members of the public interested in homeland security
This effort is built on a broad foundation of RAND homeland security research and analysis carried out both before and since the founding of the Department of Homeland Security.

Concerns about how terrorists might attack in the future are central to the design of security
efforts to protect both individual targets and the nation overall. Attacks that differ from those
current defenses are designed to address may have a greater chance of success, larger effect, or
inspire broader fear among the public. In thinking about emerging threats, security planners
are confronted by a panoply of possible future scenarios coming from sources ranging from
the terrorists themselvesâ€”from either their public statements or intelligence collected on their
deliberationsâ€”to red-team brainstorming efforts to explore ways adversaries might attack in
What should security planners do with these lists of hypothetical attacks, attacks which
can vary from new ways of using standard weapons to the application of unusual technologies like lasers to stage attacks? Should they attempt to defend against all of them, producing a
constant strain on security resources and potentially disrupting current security efforts aimed
at addressing proven threats? Or should they ignore all of them and focus on general-purpose
security approaches, thereby reducing the chances of being distracted or misdirected by threats
of unusual hypothetical attacks but potentially sacrificing the opportunity to discover currently unrecognized vulnerabilities? Given adversaries that seek not only to harm but also to
disrupt their target societies, both of these courses of action have potential negative consequences: Not responding to threats may give terrorists an advantage in attack, but overreacting to new and novel threats may achieve the very disruption the terrorists seek. As a result,
the prudent path clearly lies somewhere between these extremes, meaning that planners need
systematic and defensible ways to decide which hypothetical or unusual threats to worry about
and how to prioritize among them.
For assessing emerging and/or novel threats and deciding whetherâ€”or how muchâ€”they
should concern security planners, we suggest a commonsensical approach framed by asking
1. Are some of the novel threats â€œniche threatsâ€ that should be addressed within existing security efforts? Some novel threatsâ€”even plausible onesâ€”represent such a small
niche within the total threat posed by terrorists or other adversaries that it is very difficult to make the argument that putting specific security measures in place to address
them is justified. The judgment to classify a potential threat scenario as a niche threat
might be driven by an assessment that the attack mode provides only modest advantage
compared to currently available tactics, its characteristics make it unlikely to be broadly
adopted by attackers, the vulnerability the threat seeks to exploit is not so great to provide them major advantage, the consequences if attackers do execute the scenario are
x Emerging Threats and Security Planning
modest, or a combination of such factors. This translates to a judgment that the threat
does not merit disproportionate worry and instead can be reasonably treated as a â€œlesser
included caseâ€ within a larger part of the overall terrorist threat.
2. Which of the remaining threats are attackers most likely to be able to execute successfully and should therefore be of greater concern for security planners? Having
eliminated some emerging threats as niche threats, security planners will most likely
be left with a list of residual threats they must consider. Of those, given finite security
resources, decisions will have to be made regarding which to prioritize. In our past
work, as a stand-in for formal or quantitative analysis, we assessed novel attack scenarios
based on how difficult or risky they would be for a potential attacker. All other things
being equal (e.g., for threats with comparable potential consequences), an emerging
threat scenario that is easier for an attacker to carry out successfully should be of greater
concern to security planners than one that is more difficult to execute. This approach
uses a measure of the number and types of ways a terrorist attack scenario could break
down when attackers are trying to carry it out as a proxy measure for some elements of
the risk associated with the scenario. Use of common measures for weaknesses in terrorist plots makes it possible to compare disparate terrorist scenarios.
This two-stage approach strives to retain as many of the advantages as possible of both
extremes of response suggested above. If threats can reasonably be considered niche threats,
they can be prudently addressed in the context of existing security efforts. Doing so helps to
maintain the stability and effectiveness of those efforts and to limit the disruptiveness of terrorists suggesting new ways they might attack. If threats are unusual enough, suggest significant new vulnerabilities, or their probability or consequences means they cannot be considered
lesser included cases within other threats, prioritizing them based on their ease of execution
provides a guide for which threats merit the greatest concern and most security attention. This
preserves the opportunity to learn from new threats yet prevents security planners from being
pulled in many directions simultaneously by attempting to respond to every threat at once.
Emerging Threats and Security Planning: How Should We Decide
What Hypothetical Threats to Worry About?
We sometimes focus on tactics that may be exotic and esoteric . . . but for most terrorists, theyâ€™re
looking for what works.1
In building counterterrorism and homeland security capability, security planners at all levels
face a variety of tradeoffs. Past attacks demonstrate that terrorist groups can attack targets
many ways, and even among these proven threats, planners must weigh the costs and benefits
of different security measures and allocate finite resources among them. For example, planners
know that terrorists have staged attacks on commercial aviation with man-portable surface-toair missiles, but they still must make the difficult decision as to whether the benefits of ways
the nation could address this threat are sufficient to justify their cost. To protect both individual targets and the nation as a whole, planners must build portfolios of security activities
to deal with known and predictable threatsâ€”such as terrorists using guns and bombsâ€”while
also hedging against low-probability but potentially high-consequence attack modes. Because
effective protection from terrorism must be sustained 24 hours a day, 7 days a week, planners
must build cost-effective, sustainable security capabilities that can be justified and maintained
in the face of other competing demands on resources and other risks.
Novel and unusual threats pose a challenge to such security planning. When emerging
threats â€œpop onto the radar screenâ€ of security plannersâ€”either as vulnerabilities that have just
been discovered or attack modes terrorists have been overheard consideringâ€”they must decide
whether the new threat requires change to status quo security efforts. Some novel threats clearly
do merit concern: If the hypothetical attack does indeed exploit a previously unrecognized vulnerability, then it may significantly increase the chance of a successful terrorist attack. However, other emerging threats do not: If they are sufficiently low probability or would result in
modest consequences, disrupting current security efforts to address the new threat may create
more problems than it solves. Although there is clearly a value in adjusting and improving
security plans over time, it is also important to not create unnecessary disruption. But making
the decision that a novel threat does not merit a response carries its own risks for security
planners, in the form of professional or political consequences if a similar attack subsequently
occurs. As a result, planners need an approach to considering the range of conventional and
unconventional, plausible and fanciful ways terrorists might attack that gives them the ability to make prudent and defensible judgments as to which threats are merely distractions that

Governmental Affairs, January 8, 2009.

would consume scarce time and attention that should be spent on more-critical threats, which
in turn will help them make the difficult tradeoffs inherent in counterterrorism and homeland
security decisionmaking. Based on the results of a variety of RAND research efforts, this paper
presents what we believe is a systematic and commonsense approach for doing so.
The Variety of Emerging Threats Challenging Security Planning
Since the terrorist attacks of September 11, 2001, focused national attention on how terrorist
operations could take advantage of previously unrecognized vulnerabilities in security or defensive measures, there has been significant focus in security analysis and planning on identifying and seeking to close other potential vulnerabilities. One part of this vulnerability-driven
approach has been an effort to identify potential new attack modes or terrorist scenarios.
The nationâ€™s terrorist adversaries have been remarkably helpful and forthcoming in the
search for these potential emerging threats. Enabled by the World Wide Web and the desire of
a broader community of peopleâ€”particularly among individuals sympathetic to al-Qaeda and
jihadist-inspired terrorismâ€”to feel like they are participants in a larger terrorist struggle, vast
numbers of hypothetical terrorist plots flow through Internet chat rooms and message boards.
Examples include speculation about what infrastructures might be vulnerable to what kinds of
attack, how various esoteric chemicals might be used to injure or kill, and even how electrical
generators might be used to create lightning to use as a weapon.2 Emphasizing that even jihadist sympathizers explicitly engage in threat brainstorming, a 2009 contribution to an Internet
posting board specifically asked its members to offer up potential scenarios for al-Qaeda targeting of U.S. corporations (â€œJihadists Offer Hypothetical Scenarios, Targets for Attack,â€ 2009).
Whether the authors of the threats are truly putting them forward for consideration as actual
attacks, are trying to mislead, or are simply engaging in the terrorist equivalent of creative writing is not clear, but the potential for such scenarios to result in scattering the nationâ€™s resources
and scrambling security plans is real whatever their intent or motivation.
The open nature of this discourse has made it easy for us to see, and this pool of many possible attacks is supplemented by information gathered by intelligence agencies through other
means. Though many (or most) of the operations detected during such activities are, in the
words of John Pistole, Deputy Director of the Federal Bureau of Investigation, more â€œaspirational than operationalâ€ (â€œAlberto Gonzales Holds a News Conference on the Miami Terrorist
Cell Arrests,â€ 2006), if nothing else, they provide a constant stream of novel potential attacks
to challenge security planners. Reports of possible attack scenarios also sometimes appear in
the press when they become of sufficient concern that collected information is shared outside
intelligence and security organizations. Over the last few years, examples of such threats have
included concern about specific ways terrorists might conceal explosives, the use of remote-con2 See, for example, translations of such postings provided by the SITE Intelligence Groupâ€™s subscription-based Internet
monitoring service. Examples of such postings include: â€œSuggestion to ISI for Using Electricity as a Weapon,â€ al-Ekhlaas

trol toys in attack scenarios on airplanes (Transportation Security Administration, 2007), and
heightened concern about attacks on specific targets as a result of intelligence information.3
Beyond the myriad of threatsâ€”many fanciful, some more practicalâ€”that terrorists produce on their own, security plannersâ€™ concern about the possibilities of unidentified, lurking
vulnerabilities has led to a number of efforts to dream up new ways terrorists might attack.
These efforts often seek to identify novel or emerging threats by cross-pollinating the creativity
of terrorism analysts with ideas from technology experts, novelists, and other creative personalities. They have included government efforts such as the Department of Homeland Security Information Analysis and Infrastructure Protection Divisionâ€™s Analytic Red Cell program
(Mintz, 2004) or the Defense Threat Reduction Agencyâ€™s Thwarting an Evil Genius research
effort (Advanced Systems and Concepts Office, undated), threat brainstorming within larger
study or planning efforts,4 interactions between Hollywood writers and creative talent and
security analysts or planners to jointly dream up new types of attacks (Calvo, 2002), the work
of individual analysts or researchers examining single threats of potential concern (e.g., Baird,
2006; Deshpande, 2009; Bunker, 2008; Lockwood, 2008; see also discussion in McGill,
2008), and even unsolicited contributions by groups such as science fiction authors voluntarily
acting as outside sources of creativity (Hall, 2007; Magnuson, 2008; Barrie, 2008).
The fruits of these brainstorming activities are frequently not disclosed outside of government out of concern of giving â€œbad guys good ideas.â€ However, examples from some are available publicly. Scenarios examined in the Department of Homeland Securityâ€™s red cell program
reportedly included whether terrorists could take advantage of a hurricane in staging an attack
and specific ways high-profile events might be targeted (Mintz, 2004). The science fiction writers group put forward that they thought there is â€œa strong possibility that Al Qaeda or someone
else will set off five to ten nukes simultaneously around the countryâ€ (Andrews, 2007). Other
analyses have looked at whether specific weapon systems could be used to attack particular
targets of concern, such as the use of high-tech mortars in assassination operations (Bonomo et
al., 2007) or bringing heat-seeking missiles to bear on high-temperature components of electric
power grids (Committee on Science and Technology for Countering Terrorism, 2002, p. 181).
Individual analysts have contributed scenarios ranging from the idea that â€œa small terrorist cell
could very easily develop an insect-based weaponâ€5 for transmitting disease to the use of laser
weapons (Bunker, 2008; Elias, 2005) to â€œpyro-terrorismâ€â€”the use of large fires to cause terror
(Baird, 2006; Deshpande, 2009).
These sorts of efforts to inject imagination into security planning are reinforced each time
a successful, apparently unforeseen attack occurs; where the occurance of the attack leads to
the conclusion that past efforts to foresee new risks have involved insufficientâ€”or the wrong

Since then, concerns about failures of imagination in security planning became a common theme when considering homeland security and terrorism preparedness.
4 Emerging Threats and Security Planning
Framing a Middle-Ground Approach to Addressing Emerging Threats
Between institutionalized efforts to produce novel threat scenarios and the ideas that constantly emerge from the terrorists themselves, security planners are constantly confronted with
a wide variety of hypothetical future threats and potential vulnerabilities. So how should they
respond? Which of the nearly infinite number of possible scenarios should planners worry
about? The advantages and disadvantages of different approaches can be illustrated by the
extremes of a spectrum of possible responses.
At one end of the spectrum of possibilities, a hyper-vigilant approach would see each possible threat as requiring appropriate preventive steps and planning for response should such
an attack occur. Although planning a response to every possible imagined attack scenario
would immunize policymakers from the criticism that â€œmore could have been doneâ€ in the
event an attack does occur, forcing planners to respond to the threat-du-jour is disruptive
(and potentially discrediting) to existing security efforts, which may be effective for the vast
majority of likely terrorist threats. Adding new protections can be costly, and if additional
resources are not added to implement new prevention and response plans, security for current
threats could suffer. As security resources are stretched to try to eliminate the possibility of
terrorists flying model airplanes or breeding mosquitoes, the possibility that their performance
will suffer against more-usual threatsâ€”terrorists toting guns or planting time bombs (see,
for example, Lal and Jackson, 2006)â€”is very real.7 It is also the case that driving to respond
to every new threat risks focusing on scenarios that may or may not be that attractive to real
attackersâ€”just because a new attack option is available does not mean it will automatically be
viewed as superior to other ways of attacking by terrorist groups, nor that they will be able to
execute it successfully even if they make the attempt.8 In some cases, there can be particular
pressures aimed at selected scenarios out of the universe of possible future attacks. Whether out
of unique concern about them or other reasons, some threats can attract individual or organization advocates that push for closing specific vulnerabilities. Such pressures are less disruptive
than attempts to address every possible threat, but they can impact security plans and place
undo stress on limited resources.
Of even greater concern, attempting to respond to all possible threats and responding
to threats in an ad hoc manner both play into the hands of the very terrorist groups security
measures are intended to defeat. For terrorists that are trying to inflict economic damage on
a country, generating a stream of new threats leaders feel obligated to spend money to protect against is a very effective, low-cost and low-risk way to achieve their goals. Whipsawing a
society with a constant stream of new reasons for concern creates anxiety and fear, as well as
potentially distracting from threats of more-immediate consequence. Effective terrorists (and
other adversaries) understand the extra punch that new and unusual threats can have, and
7 An additional challenge is created because frequently, the more unusual the threat, the more specific the apparent
required countermeasure. For example, to completely address the possibility that terrorists could use model airplanes to
deliver small bombs from the air, defenses that can detect and stop such planes might seem necessary (e.g., Bolkcom, 2006;
Miasnikov, 2005). However, such defenses may protect only against this exact type of attack and not be applicable to other
types of threats.
8 For example, while many of the threat scenarios crafted in brainstorming efforts or identified in terrorist Web chatter
are very complex and intricate plots, in practice, most terrorists try to keep operations tactically simple, generally rely on
tried-and-true weapons for staging attacks, and typically plan and execute their operations on a limited budget.
Emerging Threats and Security Planning 5
consequently have every incentive to raise the specter of new weapons or tactics or to cast the
things they are doing now as new, even when they are not.
The opposite end of the spectrum would be a laissez-faire strategy intentionally worrying
less about the possibility that terrorists might find new ways to attack than that the uncertainty
about how they will do so makes responding to hypothetical threats unproductive.9 Rather
than ensuring that security measures address each emerging threat that arises, this planning
strategy focuses resources on security and preparedness measures that are not sensitive (or
are less sensitive) to where the future threat is coming from, and so will be useful whatever
unusual emerging threat scenario comes to pass.10 The key advantages of this approach are
that (1) it constrains security expenditures, (2) the investments that are made are more likely
to pay off since they are valuable in a wider range of circumstances, and (3) it limits the ability
of adversaries to disrupt security plans or cause economic damages by telegraphing new and
unusual ways they might attack. But it has the disadvantages that (1) by not paying attention
to possible novel threats security planners sacrifice the opportunity to identify unanticipated
vulnerabilities that could be inexpensively eliminated and (2) it produces the real political risk
that, after an attack, planners will be open to charges that not enough was done to respond to
known threats. It also neglects the reality that even general and versatile security and preparedness measures (e.g., public health and medical surge capacity for responding to bioterrorism,
whatever the disease) include specific elements that depend on the nature of the threat (e.g.,
fielding a comprehensive medical surveillance program, crafting medical response plans, and
developing vaccines or antibiotics for specific diseases of concern).
A prudent response to future threats obviously falls somewhere between the straw men
sitting at the extreme ends of this spectrum and would reflect differences in the nature of different threats, the targets security planners are concerned about protecting, and other factors.
But such an intermediate approach requires a systematic and defensible means of deciding
which threats to worry about and how much planners should worry about them. Ideally, the
national approach to addressing possible future threats should strive to get as many of the
advantages of both ends of the spectrumâ€”responding prudently to threats that do reveal
new vulnerabilities, but not allowing doing so to threaten the effectiveness and sustainability of existing security efforts by forcing planners to spend disproportionate time focusing on
unlikely terrorist scenarios. Analysts could use techniques such as risk analysis or cost/benefit
analysis to assess different threats and use their results as a common denominator to determine
how much we should worry about different possible attacks and the advisability of different
9 A security strategy at this end of the spectrum would also not expend resources to generate more possible threats through
brainstorming activities. Questioning the value of generating these sorts of emerging threats scenarios is the message of
what might be called a â€œcounter-brainstormingâ€ effort held by security expert Bruce Schneier. On his blog, he has staged
an annual challenge to his readers to come up with â€œmovie plot threat scenarios.â€ Movie plot threats were defined in the
inaugural contest as â€œfears [of terrorist attacks] based on very specific attack scenariosâ€ and in later years as scenarios hinging on the violent use of otherwise innocuous everyday objects to attack airliners (potentially leading to passengers being
prohibited from possessing them) and threats specifically designed to sell security or safety products. Each year the contest
has attracted hundreds of entriesâ€”which Schneier has used to make the point that such scenarios, even possible or even
plausible ones, are of comparatively little value for security planning (see Schneier, 2006 and 2007).
10 For example, in his writings, Bruce Schneier advocates for focusing investments on intelligence/investigation and emergency response (see, Schneier, 2008, pp. 15â€“19). In past RAND work, we have framed this somewhat differently as requiring tradeoffs between investments that require certainty about future threats to be effective (e.g., traditional prevention
approaches) with those that do not (e.g., robustness, resilience, and recovery from incidents) (see Jackson et al., 2008).
6 Emerging Threats and Security Planning
possible responses to them.11 However, for most emerging threats, the information needed for
a rigorous risk analysis will not be available. As a result, the security planner confronted with
many possibleâ€”and difficult to compareâ€”hypothetical attack scenarios needs more approximate ways to decide which are of most concern and suggest ways to deal with them.
This paper draws on a body of previous RAND research projects to suggest an approach
to assessing novel threats. It is informed by thinking about the relative risk of different possible attack scenarios, but implements the planning concepts developed in that body of work
in a decision-logic process rather than using formal or quantitative analysis. At the heart of this
process lie two questions to ask about novel threats:
Are some of the novel threats â€œniche threatsâ€ that should be addressed within existing
The first step of our decision-logic captures the advantage of responding to unusual threats
via standard security approaches or minor modifications of those approaches. Some novel
threatsâ€”even plausible onesâ€”represent such a small niche within the total threat posed by
terrorists or other adversaries that it is very difficult to make the argument that putting specific
security measures in place to address them is justified. The judgment to classify a potential
threat scenario as a niche threat might be driven by an assessment that the attack mode provides only modest advantage compared to currently available tactics, its characteristics make it
unlikely to be broadly adopted by attackers, the vulnerability the threat seeks to exploit is not
so great to provide them major advantage, the consequences if attackers do execute the scenario
are modest, or a combination of such factors. This translates to a judgment that the threat does
not merit disproportionate worry and instead can be reasonably treated as a â€œlesser included
caseâ€ within a larger part of the overall terrorist threat.
Which of the remaining threats are attackers most likely to be able to execute successfully
and should therefore be of greater concern for security planners?
Having eliminated some emerging threats as niche threats, security planners will most likely be
left with a list of residual threats they must consider. Of those, given finite security resources,
decisions will have to be made regarding which to prioritize. In our past work, as a stand-in
for formal or quantitative analysis, we assessed novel attack scenarios based on how difficult or
risky they would be for a potential attacker. All other things being equal (e.g., for scenarios with
comparable potential consequences), an emerging threat scenario that is easier for an attacker
to carry out successfully should be of greater concern to security planners than one that is more
11 Risk is a measure that combines information about threat (the probability an adversary will actually stage a particular
attack), vulnerability (the probability that the attack would produce damage if it was staged), and the nature of those potential consequences. Threat results from the presence of an adversary group that intends to carry out a particular attack and
has the weapons and capability to do so. Therefore, the threat can be viewed as the probability that any scenario will occur
in a given period; this probability is produced by evaluating each adversary groupâ€™s intentions and capabilities. Vulnerability
is a result of (1) the specific security and protective measures surrounding a target and (2) whether those measures address a
particular attack scenario. In the case of attack scenarios that are well addressed by current security planning, vulnerability
may be quite low. For novel attacks, however, current security approaches may not be relevant. Vulnerability can also be
thought of as the probability that an attack scenario will produce damage rather than be disrupted or defeated by security
measures. Consequences are the type and scale of damage that a successful attack can produce. In most risk analyses of terrorist incidents, consequences are estimated by the number of people that could be killed or injured in a particular attack
or by the economic costs that could result.

difficult to execute.12 This approach uses a measure of the number and types of ways a terrorist
attack scenario could break down when attackers are trying to carry it out as a proxy measure
for some elements of the risk associated with the scenario. Use of common measures for weaknesses in terrorist plots makes it possible to compare disparate terrorist scenarios.
The logical analysis underpinning our means of addressing each of these questions is
described in more detail in the following sections.
Identifying Niche Threats
When a novel threat comes to lightâ€”whether through captured intelligence, open source analysis, or threat brainstormingâ€”it is tempting to focus only on what is new about it compared to
threats that are already known and addressed by security planners. For example, upon hearing
that terrorist groups have been experimenting with the use of remote-controlled planes and
unmanned aerial vehicles (UAVs, e.g., Gormley, 2005; Karmon, 2005; Janeâ€™s Terrorism and
Insurgency Centre, 2003; â€œTroops Seize Rebelsâ€™ Explosive Planes,â€ 2002; â€œAl-Qaeda Online:
Understanding Jihadist Internet Infrastructure,â€ 2006), the fact that such technologies could
provide them with the ability to deliver bombs or other weapons from the air on any of many
targets stands out is not surprising (Miasnikov, 2005; Gormley, 2003; Verton, 2005). This specific threat was the topic of a recent RAND analysis examining how security planners might
deal with terrorist interest in these systems. In creating the framework for this analysis, RAND
developed a process for assessing whether a threat requires specialized responses or whether it
could be addressed as a lesser included case within larger portions of the threat space (Jackson
et al., 2008).13
A priori, the idea that terrorists could use UAVs to attack targets from the air seems like a
challenge to security planning that might demand a major responseâ€”and a threat that would
be difficult to treat as a subset of other threats. Measures such as concrete barriers and posted
security guards have been put in place around some potential targets such as public buildings
or infrastructure targets to keep vehicle bombs from entering, and a remote-controlled airplane
may at first blush appear to be a way that terrorists could simply fly right over these defenses.
Obvious responses to this concern might include fortifications to keep small planes from being
able to fly into key targets, radars powerful enough to detect very small aerial objects, or even
air-defense systems at important locations to shoot such â€œflying bombsâ€ out of the sky. All such
measures are aimed at the difference between this threat and others (the fact that the weapon
is being delivered from the air) and seek to directly neutralize that difference.
But by focusing on an individual novel threat independent from all other threats and on
those characteristics that set it apart from other threats, planners are only considering part of
the picture. Terrorists will not think about UAVs in isolation and security planners should not
do so either. For the terrorist planning an attack, UAVs are one possible attack mode among
many, and their use will be driven by how they compare to other options. Our analysis of
the emerging UAV threat therefore included what we called a â€œred analysis of alternativesâ€ in
12 This approach represents a movement from vulnerability-based analysis to a more threat- and capabilities-driven assessment process.
13 Our analysis investigated the potential use of both UAVs and cruise missiles in asymmetric attack scenarios in the U.S.
homeland, but for the sake of simplicity, in this discussion we will examine only UAVs.
8 Emerging Threats and Security Planning
which we explicitly catalogued the many different ways terrorists could attack targets in addition to using UAVs so that we could systematically compare the advantages and disadvantages
to terrorists of this attack mode.
For example, to solve the operational problem posed by defenses around targets, terrorists could use a UAV to deliver a bomb, but they could also choose another less-well-defended
target, chose an attack mode that could penetrate those defenses (e.g., a person carrying a
bomb into the defended building), design an attack that can overwhelm the defense (e.g.,
a vehicle bomb powerful enough to be successful in spite of the barriers or guards), or even
choose another way to attack from the air (e.g., using the mortars or rockets that many terrorist groups already routinely use) (Jackson et al., 2007). Many of the alternative ways of solving
this operational problem are weapons and tactics that are much more familiar to terrorists and
would not require them to acquire and learn to operate a UAV or remote-controlled plane.14
In addition, by identifying this attack mode as only one choice among many, our analysis
of terroristsâ€™ alternatives clearly demonstrated that UAVs have additional downsides for attackers compared to other ways they could stage an attack that would have similar consequences.
Using a UAV adds risk to attack operations that would simply not otherwise be involved. For
example, using a bomb-laden remote-controlled plane in an attack is very sensitive to the
wind and weatherâ€”with a non-zero chance of an embarrassing outcome such as the weapon
ending up stuck in a tree. A person can deliver the same bomb more predictably, rain or shine.
Furthermore, most UAV systems also constrain the size of the weapon that can be used in an
attack, limiting the scale of causalities and damage an attacker could hope to produce. Small
UAVs and many remote-controlled planes have payload capacities well below even the weight
of explosives typically carried by suicide bombers; large UAV payloads are on the order of car
bombs and from one-third to one-thirtieth the size of truck bombs (Jackson et al., 2008, p.
20). Some or all of these issues would likely make the UAV attack mode less attractive to terrorists, in spite of the UAVâ€™s possible advantages.
As a result, while it is certainly possible that some terrorists will pursue UAVs and even
use them in attacks, there appear to be no factors that would lead to their broad adoption by
many terrorist groups. Furthermore, even if they were, it does not appear that the consequences
of such attacks would be significant for most potential terrorist targets. In truth, if a terrorist
14 In our analysis, we examined a number of other operational problems where it appeared that UAVs might be of particular utility to attack planners. They were:
â€¢ If border security measures made it more difficult for attackers to enter the country, some long-range UAVs could
allow attacks to be staged from outside the country.
â€¢ If groups had only a small number of members but wanted to stage many simultaneous attacks, UAVs launched from
a single point to many targets could make that possible.
â€¢ If groups were concerned about being apprehended after staging an attack (e.g., by being identified by witnesses at
the target or through examination of closed-circuit television footage from private and government systems that captured their identity when they entered the target to stage the attack), UAVs could allow them to attack from afar and
make it easier to stage a long-term terrorist campaign.
â€¢ If groups wanted to disseminate an unconventional weapon (e.g., chemical or biological agent) over a target, a UAV
could make that easier to do.
Just as was the case for the use of UAVs to avoid perimeter security, other â€œtried-and-trueâ€ solutions to these problems are
available to potential attackers. In addition, in some cases (e.g., concern about border security excluding terrorists from
the country), it is not clear how much of a challenge these problems are to relevant terrorist groups. Finally, in the case of
unconventional weapons, terrorist possession of such weapons is a far more important concern than whether they use a UAV
or some other way of staging such an attack (Jackson et al., 2008).
Emerging Threats and Security Planning 9
was choosing between a common weapon (such as an emplaced or vehicle-borne bomb) and a
UAV carrying an explosive payload to strike a target, security planners may actually prefer he
or she use the UAV since doing so would limit the potential damage and casualties from the
attack in many cases where other means of striking the target are feasible.
This combination of likely modest use by a few groups and modest consequences from
that use leads to the conclusion that UAVs should be largely viewed as simply one more means
among many of delivering a moderately-sized bomb to a target rather than as a novel threat in
their own right. Though they can provide attackers some advantages in some situations, they
are neither game-changing nor impactful enough that they represent more than a small slice of
the overall threat faced by a modern nation from terrorism. Therefore, and because they are a
small subset of a broader threatâ€”in this case explosives useâ€”UAVs are a niche threat.
Given their niche status, security planning should then focus on how to address UAVs
within broader counterterrorism efforts rather than consider specialized defenses designed to
address them in particular. For example, major and costly changes in security measures, such
as the deployment of localized air defenses, would be unwarranted for all but the most exceptional targets because the scale of the threat would make such expensive changes nearly impossible to justify. In our analysis, the core of a prudent response to the threat of UAVs was broader
investments in measures such as proliferation control and monitoring efforts and broader policing, all of which could produce benefits with respect to both UAVs and other threats. This core
was supplemented with measures specific to the threat of UAVs only when those efforts were
low cost, such as the technical study of UAV systems that would aid in forensic investigation
should an attack using the technology occur.
Though our discussion focused on UAVs as a niche within the larger threat of terrorist
use of explosives, other examples of such threats are readily available. The concern about terrorists using remote-controlled toys in attacks discussed above is an analogous threat, representing just one of many different ways an explosive device could be initiated and providing
limited advantages over those other ways. Concern about terrorists detonating multiple nuclear
weapons simultaneously (Andrews, 2007) falls within the general threat of nuclear terrorism,
though at the highest end of the spectrum. Of the more exotic threats discussed previously,
the potential terrorist use of disease-carrying insects in attacks (Lockwood, 2008) can also be
viewed as a niche threat, though in this case a niche either within the threat of bioterrorism or
within the even broader risk of insect-borne disease, both natural and man-made.
The process of assessing emerging attack scenarios to determine if they can reasonably
be treated as niche threats has several advantages from the perspective of security planning.
Forcing comparisons with the many ways that terrorist groups have available to stage attacks
nowâ€”rather than only focusing on those characteristics that make a new threat newâ€”forces
the objective assessment of how much of an advantage an attacker would really achieve by pursuing a novel attack. If that advantage is modestâ€”i.e., the scope of the potential consequences
compared to other attacks is similar or smaller and the operational characteristics are not substantially superiorâ€”then there will be less of an incentive for terrorists to pursue that attack
mode in the first place. Consequently, there is less reason for security planners to attempt to
defend against the threat. Defaulting to addressing such threats within existing security measures is then a prudent way to hedge against the risk that some attackers might attempt the
attack, but it also limits disruption to existing security efforts and reduces the chance of diverting security resources to a low-probability threat.
10 Emerging Threats and Security Planning
Prioritizing Emerging Threat Scenarios
But what about attack scenarios that canâ€™t be treated as niches of more general threats? Terrorists using lasers as weapons (Bunker, 2008) or building devices to produce synthetic lightning15
are unusual enough scenarios that they are difficult to treat as lesser included cases of other,
more-common threats. But just because a threat is new does not mean security planners must
worry about it. Given finite resources, security planners need approaches to help decide how
much they should consider even genuinely novel threats and of those, which they should tackle
first and how much should be spent doing so.
This problem is further complicated by the need to compare threats that are very different to make decisions regarding the allocation of limited security dollars. It is not easy to
compare threats as diverse as laser attacks and synthetic lighting, much less compare them to
more pedestrian terrorist tactics such as bombings or armed attack. This difficulty in comparing threats can be a further pressure toward putting security measures in place for each of them
individually, thereby sidestepping the need to compare them. But security planning undertaken in this manner can quickly get expensive. Common denominators are needed to make it
possible to weigh different threat scenarios and make judgments about which merit customized
security measures, which should be addressed by general measures like response and recovery,
and which can most likely be ignored.
So how might security planners compare such disparate threats? One obvious element is
some estimate of potential consequences of an attack, where higher potential consequencesâ€”
many casualties or a high degree of damageâ€”would make an emerging threat of greater concern. But focusing on consequences alone provides only a partial picture, ignoring the other
two components of riskâ€”threat and vulnerabilityâ€”that drive the likelihood of a terrorist
attempting an attack via that mode and whether the potential targets would be damaged
should such an attack be staged. However, for most emerging or hypothetical threats, a rigorous risk assessment is impossible because, almost by definition, planners cannot know the
probability that such attacks will be attempted or what targets (vulnerable or not) they might
be carried out against. To sidestep this problem, we use an approach that compares different
terrorist operations by ranking them based on the estimated likelihood terrorist attackers will be
able to carry them out successfully. This process includes asking questions about how easy or hard
it would be for attackers to execute a specific attack scenario given its requirements and characteristics (an aspect of threat) and the potential effects of security measures on their likelihood
of success (an aspect of vulnerability). To do so, we drill down into the details of each emerging
threat scenario to uncover the practical elements of what would actually be involved in staging
an attack using a novel weapon or tactic.
At a detailed level, some attack modes are simply more likely to encounter problems
than others. For example, terrorists relying on improvised weapons (e.g., homemade mortars)
wouldâ€”in generalâ€”be more likely to encounter problems than groups using proven commercial weapons (e.g., mortars produced by an arms manufacturer). Similarly, very complicated
operations (e.g., attacks dependant upon multiple events occurring in tight succession) would
be more likely to break down than more-simple attack plans. Sometimes terrorists can hedge
against these risks; sometimes they cannot. In our work, we identified six general characteris15 SITE Intelligence Group translation of jihadist internet posting on the al Ekhlaas forum, â€œSuggestion to ISI for Using
Electricity as a Weapon,â€ translation dated June 13, 2008.
Emerging Threats and Security Planning 11
tics that affected the likelihood of a terrorist operation running into problems or failing entirely.16 Those characteristics are summarized in Table 1.
If emerging threat scenarios can be systematically assessed to identify how they differ
based on these characteristics, then even very different types of operations can be compared,
since common failure modes and the factors that shape the likelihood of those failure modes
causing the operation to go awry provide a common basis for comparison.17 Combined with
an understanding of the potential consequences of different operations, it can also provide the
basis for prioritization of threat scenarios: All other things being equal, novel threat scenarios
that are robust and more likely to succeed should be of greater concern than intricate and complicated operations that, although they might be attempted by attackers, are much more likely
to break down as a result of their operational requirements, skill demands, and other factors.
Actually executing this approach to assess specific emerging threat scenarios requires a
process to systematically measure them against the six factors in Table 1. To do so, we devel16 In designing small-unit operations, military organizations have established processes for thinking through factors that
could threaten operational success. One example of these processes is the Mission, Enemy, Terrain, Troops and Equipment,
and Time Available analysis method used by the U.S. military to perform operational risk analysis. The general characteristics that we identified to assess possible terrorist scenarios roughly parallel the elements of that structure, which include
assessment of how equipment (technology), opposing actors (from the perspective of a terrorist, the security forces), operational design (including complexity) and other unexpected factors could increase the chance of a negative outcome in a
military operation. See, for example, U.S. Army, 1998.
17 This general approach is derived from such risk analysis methods as fault-tree analysis and failure-mode-and-effects
analysis, but our approach is much more conceptual and qualitative than is usual in these formal methods (see, for example,
Haimes, 2004, Chapter 13, for a discussion of these techniques. An example of the use of fault trees for analyses relating to
terrorism is available in Shooman, 2006).
Characteristics of Attacks Related to Operational Risk
Characteristic Operational Risk
Operational Complexity and Difficulty
Technology characteristics Operations that rely on tried-and-true technologies involve
fewer risks than those that rely on improvised or very complex
Skill requirements Operations that rely only on general knowledge that attackers can
develop on their own are less demanding than those that require
very specialized skills that might require training to develop.
Requirements for simultaneous or
tightly sequential actions
Operations that require that actions occur either at the same time or
in a specific order over a short period to be successful are riskier than
those that do not.
Potential Operational Breakdowns
Elements that make operation
detectable by security organizations
or law enforcement
Operations that require overtly hostile action or are inherently
detectable are more likely to fail than more-clandestine activities.
Potential protective measures to
prevent or disrupt the attack
Operations that are sensitive to the security and protective measures
around a target are more likely to fail than those that are insensitive
Reliance on events outside
the attackersâ€™ control
Operations that rely on events (e.g., the exact time a target will
arrive at a specific location) that are not under the attackersâ€™ control
involve more risk than those that do not.
12 Emerging Threats and Security Planning
oped high-medium-low ranking scales for each of the characteristics and measures for the
complexity of different attack operations to qualitatively score risks for different scenarios.18
Table 2 presents an example of a scale for rating a scenarioâ€™s technical risk. Similar scales can
be constructed for the other characteristics and the ways that different failure modes could
occur in different phases of an operation, including preparing for the attack (e.g., manufacturing weapons), approaching and engaging the target, carrying out the attack itself, and (if
applicable) disengaging and escaping.
In laying out these sorts of scales for ranking different operations, we do not mean to
imply that the terrorist attackers are choosing operations or making their own decisions based
on this sort of systematic process. While it is not inconceivable that some mightâ€”and there
is certainly evidence that attackers take factors such as risk or their level of confidence in their
weapons into account as they think about operationsâ€”it is unlikely that any group would
use as structured a process as the one outlined here. That said, even if no terrorist makes decisions in this manner, it is still useful for security planners to break down potential terrorist
operations systematically because the factors they identify will contribute to whether or not
an attempted operation is likely to succeed no matter how approximate or non-systematic a
process the attackers went through to reach the conclusion that staging the attack was a good
Returning to the two novel threat scenarios used as examples previouslyâ€”terrorist use of
lasers and their building a machine to generate artificial lightningâ€”it is easy to see how this
sort of qualitative ranking process can be used to differentiate among very different hypothetical attacks. Assuming that an attacker would buy an industrial or scientific laser, that attack
scenario would have a low risk of technical failure because it was using a proven commercial
technology. On the other hand, a terrorist attempting to build his own lightning machine
would definitely fall into the high risk category because such a device would certainly qualify
as an elaborate, improvised weapon.
18 The more moving parts the success of an operation depends on, the more likely a disconnect between one or more of
those parts will cause it to fail. For example, a single attacker walking up to a person and shooting him or her has only one
component. On the other hand, an attack in which terrorists use one bomb to blast their way through security to allow
another bomber to enter a facility and blow it up from the inside has two, and breakdowns in timing between them or the
failure of one would threaten the entire operation. The more closely different moving parts must happen in time, the greater
the risk. An attack team required to successfully carry out two (or more) tasks at exactly the same time has a higher risk of
failure (because of the coordination and skills required) than one that must conduct two tasks that need only occur within
minutes or hours of each other.
Risks Related to Technical Issues During an Attack
Risk of Failure Attack Type
High Attack uses elaborate, improvised weapons or other technologies (e.g., an
improvised missile or a chemical or biological dispersal device).
Medium Attack uses basic improvised weapons or other technologies (e.g.,
improvised explosive devices, a commercially manufactured poison that
can be directly administered, or simple improvised communication modes).
Low Attack uses proven commercial off-the-shelf weapons or other
technologies (e.g., firearms, military weapons, commercial communication
Emerging Threats and Security Planning 13
The risk of technical failure applies to more pedestrian parts of operations as well, such
as even getting to the target itself. An attacker using a car to drive to their target would have a
low failure chance (automobiles are a proven commercial technology), but one that was flying
there on a home-built powered parachute19 would be in the high category.
With rating scales for all of the elements in Table 1 for ranking the ways emerging threat
scenarios might break down at different phases of the operation, a security planner or analyst
has the basis for comparing even very different types of operations.
Simple, single step attacks in which attackers take advantage of proven technologies would
have mostly low-risk scores, highlighting the greater robustness of such operations where fewer
things could go wrong. Even though it represents an exotic threat, some terrorist use of lasers
(e.g., use of high-power industrial lasers in antipersonnel attacks or in attempts to incapacitate
pilots in flight; see Bunker, 2008), would fall into this category because they require only the
application of commercial off-the-shelf technologies in straightforward operational designs.
Attacks with a low risk of failure merit more attention from security planners than scenarios
with comparable consequences but higher chances of attacker failure.
More-complicated operations in which attackers have to rely more on improvised technologies or specialized skills or the success of which depends on factors beyond the terroristsâ€™
control (e.g., attack scenarios that rely on a crowd panicking to produce additional causalities)
would receive more medium risk rankings.
Very complex terrorist scenarios (such as those one might see in movies or in television
shows) that have many separate components, rely on high-technology weapons built by the
terrorists themselves, are subject to many variables outside the attackersâ€™ control, and require
split-second timing would pile up impressive totals of high risk scores, reflecting the difficulties an actual terrorist group would have pulling them off.20 Compared with other scenarios
with comparable consequences, scenarios that are very high risk for attackers would merit less
attention from security planners because fewer adversaries would have the skills needed to pull
them off and, if attempted, they have a greater chance of collapsing under the weight of their
complexity and difficulty.
Just as was the case for identifying niche threats, determining that a particular scenario
has a high chance of failure in many of its components does not mean that the operation will
not happen. Scored in this manner, the September 11, 2001, terrorist plots would have fallen
high on a number of risk scales, depending as they did on how the passengers on the flights
reacted, on advanced piloting skills that the attackers had to acquire through training, and so
on (see National Commission on Terrorist Attacks on the United States, undated). But success19 SITE Intelligence Group translation of an al-Ekhlaas posting, â€œRemote-Controlled Cessna 128 SkyLane and Parachute
Guides for Jihad,â€ translation dated March 25, 2008.
20 To illustrate this dynamic, we assessed the terrorist plot in the fourth season of the television series 24 based on episode descriptions from the Fox networkâ€™s Web site (http://www.fox.com/24/episodes/season4/). Based on a conservative
examination, that plot involved more than 50 separate steps, most of which had to occur within narrow time windows and
included high-risk operations such as kidnappings of Cabinet-level officials, cyberattacks on large numbers of infrastructure
targets, the complete destruction of a train with a vehicle bomb and the air-to-air engagement of a well-defended airliner
(Air Force One) while recovering specific objects from the wreckage of both vehicles, the theft of defended military hardware (including a stealth fighter and a nuclear weapon), and integrating a stolen nuclear weapon into a customized missile
for delivery to a distant target. Such a complex operation, the overall success of which hinged on the sequential completion
of one nearly impossible task after another, may make for a gripping season of television but would be beyond the capabilities not just of any realistic terrorist group, but most nation-states as well.
14 Emerging Threats and Security Planning
fully carrying out operations with greater risk of failure requires more sophisticated attackers,
meaning an operation with many high-risk rankings will be within reach for many fewer terrorist groups than simpler and more-robust attacks.
These comparisons of threats based on the details of the operations and the technologies
involved are intentionally silent as to which particular terrorist group might try to carry them
out, allowing threat scenarios to be compared without specifying from where a threat is comingâ€”or might comeâ€”in some unknown future circumstance. Although of limited value for
some evaluation purposes (e.g., the results of such a ranking should not be viewed as the probability a specific attack type will occur), this approach is useful because (1) emerging threat
scenarios are often crafted without a specific attacker in mind during threat brainstorming
and (2) intelligence that picks up chatter about possible future threats may or may not provide
much insight into the actors considering them.
Though our discussion has focused on emerging threatsâ€”including scenarios as fanciful
as terrorists constructing and deploying artificial lightning machinesâ€”our ranking approach
can also be used to compare novel threats with operations that terrorists carry out routinely.
For example, most simple â€œguns and bombsâ€ terrorist operations would have low-risk scores,
reflecting the robustness of most of the technologies involved and the simplicity of most of the
operational designs. More-complex attacks, such as the use of advanced weapons such as the
man-portable surface-to-air missiles mentioned in the introduction to this paper, would have
somewhat higher risk scores given the greater sophistication of the technologies, the limits in
the ability of groups to build expertise using them, and so on. Reflecting the fact that this
analytical approach is designed to distinguish lower-risk emerging threats from ones that are
more similar to these â€œtried and trueâ€ terrorist operations, there would be little overlap between
the rankings of these operations and many of the attack modes terrorists have postulated in
creative-writing exercises circulating on the Internet or the complex and intricate attacks more
appropriate for a screenplay than the operational plans of any real-world terrorist group. As
a result, security plannersâ€™ attention and resources would be preserved for these more serious
threats, and these others could be defensibly set aside.
Conclusions: Security Planning for the Niche and the Novel
Underlying this discussion of how to assess emerging threats is the belief that there is a value
in stable security approaches that are acceptable to the people they are intended to protect and
that are sustainable over time. If this is indeed the case, wrenching security efforts this way and
that to respond to every potentially new threat that pops onto the national radar has a substantial cost. Although the new customized security measures implemented as part of a response
to a novel threat have a direct cost, these measures also have indirect costs in terms of the disruption they may cause to ongoing security efforts and in terms of both public confidence and
fear. The goal is therefore to strike the right balance between hypervigilance to every possible
new threat and ignoring ways such threats might change over time.
But assuming that security planners are neither going to ignore emerging threats nor react
to them all, reasonable ways to decide which ones to give attention to are needed. Based on our
past work assessing a variety of different threats, we have suggested an approach that can act
as a filtering mechanism for both the results of our own threat exploration and the constant
Emerging Threats and Security Planning 15
stream of possible future attacks our adversaries either publicize themselves or we discover
through intelligence collection.
Identifying those novel threats that are best thought of as niches of larger threats makes it
possible to filter out possible attacks that, while they might be new to terrorists, do not require
new security plans or customized security measures. To the extent that such threats can be
made lesser included cases of more general threatsâ€”and therefore be addressed by more-general security measuresâ€”the country benefits through more stable, simple security strategies
at likely less cost. As was the case in our analysis of the threat of attacks using UAVs, it may
be possible to prudently respond to a threat with just incremental changes to existing security activities. Resisting the temptation to put specific new security measures in place for each
niche threat has an additional advantage when considering the fact that terrorist groups study
and respond to the defenses deployed against them. The more specific the niche and the more
specific the countermeasure aimed at addressing it, the easier it is for an attacker to respond by
simply moving to a different niche of the same threat and rendering whatever investment was
made in the countermeasure irrelevant (Jackson et al., 2007).
For new threats that are indeed new and cannot be as readily addressed by general security efforts, it also does not immediately follow that major changes in strategy or customized
security measures are needed. Threats must be assessed systematically and prioritized because
it is simply impossible to protect every possible target against every possible current and emerging threat. Attempting to protect against everything in a world of finite resources is remarkably
similar to protecting against nothing, only much more expensive. Choices will always have
to be made. We have described a process for using the details of threat scenariosâ€”and how
those details shape the likelihood of an attack failingâ€”as method to compare very different
hypothetical attacks. Such an approximate ranking method seeks to apply the concepts of risk
analysis to situations where the data needed for accurate risk assessment simply does not exist.
Though it is impossible to affirm that a particular type of attack will never happen, a scenario
with a high failure chance would reasonably be of less concern than one with comparable consequences that was simple and straightforward.
Although a ranking scheme provides a way to prioritize threats, it does not provide absolute answers as to how far down that list of priorities security investments should be made as
a hedge against possible future attacks. Such resource-allocation decisions involve additional
considerations, and the choice could be very different at some targets than at others. As security planners shift from thinking through what emerging threats they should worry about to
what to do in response, cost-effectiveness questions will also come into play: If it is possible to
address some threats that are lower on the list at very little cost, it might be worth it to do so
in spite of the relative likelihood of their taking place. But starting from a prioritized list will
always be better than attempting to deal piecemeal with threats as different as terrorist insects,
exploding remote-controlled planes, and artificial lightning and making decisions in isolation
as to whether resources should be diverted from threats we can reasonably expect tomorrow to
hedge against a very uncertain future.
