Corrupted Science

I recently finished a book by John Grant - Corrupted Science. In it, Grant describes an endless parade of examples where the scientific principles have been violated (sometimes resulting in tragic loss of human life), starting from faking observation data by Ptolemy and Galilei to the illnesses hampering modern science in the US.

I think it should be required reading for aspiring scientists. On the one hand, it demystifies the image of science, which is often seen as something that is absolute, certain (100%) and infallible, while in reality it is often not the case. On the other hand, it urges you to avoid the various pitfalls or mistakes that have happened before, and hopefully make you a better and more moral scientist.

It is especially instructing to see the vast array of examples from recent years. Otherwise, we could just look at the chapter on Hitler's Germany and Stalin's Russia and dismiss it as "ancient" history. However, it is followed by an account of politically corrupted science from the US during the Bush (II) reign.

Georgia 2008 and Cyber Neutrality

I happened across an article [pdf] about neutrality in cyberspace by Korns and Kastenberg. In the article, the authors analyze an aspect of the 2008 Georgia cyber conflict that usually receives little attention: the fact that the Georgian government moved some of its online services to other countries during the war. Specifically, the authors worry about what this means to the neutrality of the host countries.

While they raise an interesting question, I do have some issues.

First, there is the question of whether US lost neutral status in the Russia-Georgia war by hosting some services:
"The fact that American IT companies provided assistance to Georgia, a cyber belligerent, apparently without the knowledge or approval of the US government, illustrates what is likely to become a significant policy issue."
Were Georgian websites under attack? Yes, no doubt. Was this a part of the Russian war campaign? Maybe, but at least officially the Russians deny their involvement. Well, if neither belligerent takes responsibility for the attacks, then we can't really refer to Georgia as a "cyber belligerent" (what does this mean, anyway?). We are left with attacks that do not amount to war, but crime or political hactivism, and I am unaware of any international prohibition on cooperating against criminals or hactivists - even on the business level. Besides, blaming Georgia for this decision is similar to arresting the victim of a street mugger, as the only known party in the criminal act.

Then there is the question of the type of aid that was provided to Georgia (citing a Supreme Court decision):
"If the US government establishes a strict position of neutrality, American industry may provide nonmilitary and humanitarian support to a belligerent, but firms are required to halt all commerce that militarily aids a combatant."
I believe this is undiscovered country. Presumably, the drafters of this document kept in mind the physical goods industry, whereas in cyberspace we are mostly concerned with services. Is hosting a government public relations website "commerce that militarily aids a combatant"? I would argue against that, because otherwise US would have to pull the plug on EVERYTHING every time there is a conflict where US remains neutral (although there is a question whether US was truly neutral in this case, as illustrated in the paper).
"Under a traditional international law rubric, to remain neutral in a cyber conflict a nation cannot originate a cyber attack, and it also has to take action to prevent a cyber attack from transiting its Internet nodes."
Since US is one of the leading nations harboring ISPs with questionable practices, and is also home to a large number of malware infected computers (bots in a botnet), then any time you have a large DDoS attack, US is likely to be on the "attack source" list [to be fair, the authors have also covered this aspect]. I consider it quite likely that at least some US-based computers were used against the Georgian sites during the war. If the Russian Federation was behind the attacks, does this mean that US lost its neutrality and became a belligerent? Again, I would say no. It would be great if US could clean up its part of the Internet, though.

The rest of the paper does a quick analysis of several potentially applicable laws and treaties. Again, while I do not agree with all of their conclusions, they have done a very good job of pulling together thought-provoking concepts. I highly recommend reading it.

These are just some first reactions, but I can see that I need to do some deep thinking on the subject.

Jeffrey Carr Inside Cyber Warfare

Jeffrey Carr's new book, Inside Cyber Warfare came out late last year and is an interesting resource for the cyber researcher. If you are familiar with the Grey Goose Reports I and II and have been reading Jeff's blog at IntelFusion, then a lot of the material will look familiar.

The book covers a lot of ground (pretty much all of it), but this is also its weakness. The principle of universality vs effectiveness states that there can't be both at the same time. Therefore, the book feels at times like a train ride - interesting scenery is rushing by, but you do not catch the full richness of it, just glimpses.

I found the Grey Goose Reports an interesting read, although somewhat rough around the edges. Granted, they were done under serious time constraints and included input from many people, so it was to be expected. I'm glad to see that Jeff has polished away a lot of that.

Jeff goes through a host of examples of recent cyber conflicts, specifically looking at potential state-sponsored events like the Russia-Georgia (cyber) conflict of 2008. He includes a lot of small facts and stories that may not have caught your attention before, so it pays to read the book instead of just scanning over it quickly.

On the other hand, however, I find that the biggest problem with Grey Goose and this book is that in the end, they are just stories with a plausible explanation. To me, there is still no concrete PROOF of state involvement in Georgia 2008, even though there are a thousand circumstantial evidence arrows pointing at it. So we are stuck with the attribution question, again.

This brings me back to my own research - understanding "independent" online cyber militia and looking for ways to deal with the phenomenon. I'll have a post on some potential tactics soon.

As I said above, the book definitely contains a lot of interesting information and may provide you with the interesting fact or angle that was missing, if you are researching cyber conflicts. So, if you get the chance, read it.

The Schmitt analysis, Part II

This is my second post that looks at the legal aspects of cyber conflicts. As Sean pointed out, Schmitt also wrote a piece in 1999 that gives a framework for evaluating whether or not jus ad bellum applies to cyber conflict. The text is available here [pdf]. Note that the last post was about jus in bello and this one is on jus ad bellum, which the author defines as:
"... that body of international law governing the resort to force as an instrument of national policy ..."
... or in other words, when is it ok to go to war. The article limits the scope to CNA between state actors, which is good, because applying the laws of war on non-state actors is always tricky. In the end, however, it needs to be done, because many of the actors in the cyber conflicts of today are definitely not state actors. Schmitt poses two generic scenarios of interest:
"In the first, State A conducts CNA operations against State B with no intention of ever escalating the conflict to the level of armed engagement. The advantages gained through the CNA are ends in themselves. In the second scenario, State A conducts CNA operations in order to prepare the battle space for a conventional attack. The goal is to disorient, disrupt, blind, or mislead State B so as to enhance the likelihood that conventional military operations will prove successful."
He again stumbles on the issue of whether or not CNA constitutes "use of force" if the legal text is interpreted the traditional way. He then brings counterexamples of "lawful" use of force, which require a different analysis approach. Schmitt analyzes the text, looks at the history behind it, and shows how the application of law has evolved over time with court cases. He arrives to the conclusion that in the end, what matter are the consequenses.

He provides a list of criteria to be analyzed in order to check whether a cyber attack could be considered "use of force" in terms of international law. Here they are:
"1) Severity: Armed attacks threaten physical injury or destruction of property to a much greater degree than other forms of coercion. Physical well-being usually occupies the apex of the human hierarchy of need.
2) Immediacy: The negative consequences of armed coercion, or threat thereof, usually occur with great immediacy, while those of other forms of coercion develop more slowly. Thus, the opportunity for the target state or the international community to seek peaceful accommodation is hampered in the former case.
3) Directness: The consequences of armed coercion are more directly tied to the actus reus than in other forms of coercion, which often depend on numerous contributory factors to operate. Thus, the prohibition on force precludes negative consequences with greater certainty.
4) Invasiveness: In armed coercion, the act causing the harm usually crosses into the target state, whereas in economic warfare the acts generally occur beyond the target’s borders. As a result, even though armed and economic acts may have roughly similar consequences, the former represents a greater intrusion on the rights of the target state and, therefore, is more likely to disrupt international stability.
5) Measurability: While the consequences of armed coercion are usually easy to ascertain (e.g., a certain level of destruction), the actual negative consequences of other forms of coercion are harder to measure. This fact renders the appropriateness of community condemnation, and the degree of vehemence contained therein, less suspect in the case of armed force.
6) Presumptive Legitimacy: In most cases, whether under domestic or international law, the application of violence is deemed illegitimate absent some specific exception such as self-defense. The cognitive approach is prohibitory. By contrast, most other forms of coercion—again in the domestic and international sphere--are presumptively lawful, absent a prohibition to the contrary. The cognitive approach is permissive. Thus, the consequences of armed coercion are presumptively impermissible, whereas those of other coercive acts are not (as a very generalized rule)."
An example of the use of the Schmitt analysis in a more quantitative form is available here [pdf].

He spends a fair amount of time analysizing what actions could be taken in response to CNA. He comes up with a relatively simple decision procedure:
"1) Is the technique employed in the CNA a use of armed force? It is if the attack is intended to directly cause physical damage to tangible objects or injury to human beings.
2) If it is not armed force, is the CNA nevertheless a use of force as contemplated in the U.N. Charter? It is if the nature of its consequences track those consequence commonalities which characterize armed force.
3) If the CNA is a use of force (armed or otherwise), is that force applied consistent with Chapter VII, the principle of self-defense, or operational code norms permitting its use in the attendant circumstances?
a) If so, the operation is likely to be judged legitimate.
b) If not and the operation constitutes a use of armed force, the CNA will violate Article 2(4), as well as the customary international law prohibition on the use of force.
c) If not and the operation constitutes a use of force, but not armed force, the CNA will violate Article 2(4).
4) If the CNA does not rise to the level of the use of force, is there another prohibition in international law that would preclude its use? The most likely candidate, albeit not the only one, would be the prohibition on intervening in the affairs of other States."
A second decision procedure is available for determining whether or not a response with armed force is applicable:
"1) If the computer network attack amounts to a use of armed force, then the Security Council may characterize it as an act of aggression or breach of peace and authorize a forceful response under Article 42 of the Charter. To constitute an armed attack, the CNA must be intended to directly cause physical damage to tangible objects or injury to human beings.
2) If the CNA does not constitute an armed attack, the Security Council may nevertheless find it to threaten the peace (the absence of inter-state violence) and authorize a use of force to prevent a subsequent breach of peace. The CNA need not amount to a use of force before the Council may determine that it threatens peace.
3) States, acting individually or collectively, may respond to a CNA amounting to armed attack with the use of force pursuant to Article 51 and the inherent right of self-defense.
4) States, acting individually or collectively, may respond to a CNA not amounting to armed attack, but which is an integral part of an operation intended to culminate in armed attack when:
a) The acts in self-defense occur during the last possible window of opportunity available to effectively counter the attack; and
b) The CNA is an irrevocable step in an imminent (near-term) and probably unavoidable attack."
The paper contains a lot of insight (at least to an outsider like me) of how the international law works and what may be the questions asked after the first real cyber war. I highly recommend reading this paper in full to get the picture. I know the author is currently working on updating the analysis, but until then, we must wait.

The Schmitt analysis

Here is a bit of reading from 2002 that is still relevant today. Michael N. Schmitt wrote an article called "Wired warfare: Computer network attack and jus in bello" [pdf], where he explored what the international humanitarian law has to say about CNA. It should be required reading for all of us cyber conflict researchers, as sooner or later we will have to tackle with showing how our theories work (or not) in the framework of existing laws. And the article shows, that lawyers' concerns are often a bit different from what we might expect.
As an anecdote, I found it very funny when Richard Nixon's head (President of Earth in Futurama), faced with a legal obstacle, says something along the lines of: "Well, I know a place where the Constitution doesn't mean squat!" and the camera zooms to the Supreme Court. [from memory, so it may be a little inaccurate]
For those who are a unsure what jus in bello means, he provides a definition:
"... that body of law concerned with what is permissible, or not, during hostilities, irrespective of the legality of the initial resort to force by the belligerents."
With that clear, let's move on. He quickly analyzes whether the international humanitarian law applies to CNA at all and finds that yes it does, if it can be classified as 'armed conflict'. That, in turn, requires that 'armed forces' are engaged in the conflict. However, the link between CNA and armed forces is not very strong, so he analyzes the contradictions in the text of the law and its application to conclude that:
"... humanitarian law principles apply whenever computer network attacks can be ascribed to a State are more than merely sporadic and isolated incidents and are either intended to cause injury, death, damage or destruction (and analogous effects), or such consequences are foreseeable."
Obviously, the biggest problem here is the attribution. Cyber is very much a silent service when it comes to taking credit for the really complicated and high profile attacks. Government A could very well pull off a 'cyber war' and remain anonymous. Better yet, make it look like it came from Govt. B.

Since direct injury and death is presumably difficult to reach with cyber, let's discuss the other two. Would financial loss be enough to evoke the damage criteria? If so, how much loss are we talking about? Does destruction only apply to physical objects or is information also on the menu? What if an attacker drops all tables in the national registry of [CLASSIFIED] and manages to mess up the backups as well? The truth is out there...

Schmitt follows a trail of deductions similar with the 'armed conflict' with the concepts of 'targeting' and 'attack' in the law. He also touches the classification of targets to combatants and military objectives, civilians and civilian objects, as well as dual use objects. He discusses targeting economic systems (stock market, banks etc) as military targets and once again returns to the threshold of 'injury, death, damage or destruction'.

The civilian section includes an interesting bit about contractors or civilians who perform cyber attacks. He points out that those civilians (and contractors) with an official tie to the military could still be targeted and could be considered prisoner of war (because they are 'accompanying the armed forces'), if captured. On the other hand, if civilians launch the attack and they do not have an official connection, they would be 'illegal combatants' (who may still be attacked). This is only in case where the cyber attacks are severe enough to pass the threshold mentioned above.

Unfortunately his section on dual use objects is relatively short. I think the dual use category is extremely important in cyber context, as one could argue that most systems could potentially be dual use (Internet, for example, can serve as a backup communication system for the military and it is most likely going to be the main battlefield of cyber conflict). This is definitely one aspect that merits further study.

He shows that the legal framework actually supports cyber attacks over kinetic in some cases, such as shutting down dams and nuclear power stations (which you should not do with kinetics).

He analyzes several aspects of CNA targeting, including discrimination, distinction, proportionality, collateral damage, incidental injury and perfidy. I think the difference between a perfidy and a ruse is what would often get IT guys in trouble.

Overall, he covers a lot of ground and to my knowledge, there is still no better, definite answer on what is and is not allowed in cyber space. As always, read the paper for full info.

Milblogging, ad-hoc cyber militia and science

I read an paper by Sean Lawson, about the debate and conflict [pdf] between the US Army and the Milblogging community (servicemembers who blog about their experience in the military, including combat reports).

While the article focuses on the blogging servicemen, we should also make a note that the same tool is available to everyone. This spontaneous "online, volunteer public affairs or information operations corps" would be a perfect rallying tool for an ad-hoc cyber militia. Consider, that there are numerous blogs on controversial issues (including pro and contra sides for each), which typically have a steady readership, even if it is small. All it takes is for the blogger to post a rally cry (and some instructions) and an ad-hoc cyber militia is formed and ready for action.

Members of such a group are pre(self)selected and have strong feelings about the issue. Therefore, they probably need very little persuasion to join up.

If you have the time and the interest, there is also a link to his Doctoral Dissertation on his web site. It gives a good overview of the development of the science of war, explaining the heritage of terms such as OODA loop and netcentric warfare, as well as providing an overview of the relation between US military and the scientific community. Interesting to read. Nearly 400 pages, however, so be warned.

Russia and Cyber Attacks

A colleague pointed me to an article in the Baltic Security and Defence Review, an annual publication of the Baltic Defence College (international staff college for military officers at OF3-OF5 ranks). MAJ William Ashmore (US Army) writes an overview of recent cyber conflicts with Russia, titled "Impact of Alleged Russian Cyber Attacks" [pdf].

While the article covers a lot of ground it seems that he is not a subject matter expert in cyber conflicts. The quality of the references is relatively weak (mostly public news media) and there are a few simple errors. On the other hand, he has done a fairly broad background check for the legal/doctrinal work done at OSCE, UN etc.

He provides an overview of events in Estonia 2007 and Georgia 2008 among others, and a summary of NATO's activities in setting up cyber defence. He spends some time on Herman Simm's case (highly placed spy for Russians in Estonian MoD, caught 2008), although to me his arguments there seem a bit weak.

He reviews the national and international responses/comments to the Russian cyber campaigns, including potential attribution. There is also a fairly interesting chapter about future trends in Russian cyber activities (including Dr Panarin's recommendations). I think he may be onto something when he says that in Russia, cyber is mostly seen as an offensive capability.

With the US primarily focused on the Chinese cyber threat, the Russian (and other) cyber studies remain in the background. Therefore, it is a refreshing piece of reading, regardless of some issues with depth or quality. As always, read the article for full info.

Happy holidays!

McAfee's Virtual Criminology Report 2009

I set aside some time this week to read the McAfee Virtual Criminology Report 2009 [pdf]. It has a provocative sub-title "Virtually Here: The Age of Cyber Warfare" that caught my eye. So, what was useful in there for me?

As the foreword (by CEO of McAfee) already points out, politically motivated cyber attacks are on the rise and the term cyber crime is not fit to describe them well. The foreword also makes the important point that this report comes from a private sector perspective, unlike the usual government/military perspectives on cyber warfare. As it turns out later, however, it is more of a broad spectrum overview that doesn't really focus on any special sector or issue.

The report gives a short overview of the events in Estonia 2007, Georgia 2008 and US/South Korea 2009. The Georgian overview is based on the US Cyber Consequences Unit overview [pdf], which is the public high-level summary of a more detailed report.

Of more interest is the method for cyber attack attributes that is presented on pages 8-9. Experts will assign values to a cyber conflict in four categories to determine the severity of the event (no reference):
"Source: Was the attack carried out or supported by a nation-state?
Consequence: Did the attack cause harm?
Motivation: Was the attack politically motivated?
Sophistication: Did the attack require customized methods and/or complex planning?"
They have provided a table for assigning values and have applied the model on the three conflicts mentioned earlier, providing a bar graph. I have done similar work in my Master's studies. In retrospect, it is only of limited use, because the values are highly subjective and in the end - it does not prove anything.

The report also mentions many well known issues in cyber conflict, including:
  • many nations are preparing for cyber war, but covertly
  • criminals and politically motivated attackers use the same tools and techniques
  • criminal groups may cooperate with governments
  • financial and other critical information infrastructure is at high risk
  • sharing threat information is good
  • there is a need for a public debate about the use of cyber weapons
  • the attribution problem and a nice intro to the cyber deterrence issue
  • the need for updated legal measures
  • cyber espionage
  • etc.
On one hand, this report should bring little new information for the experts and researchers that focus on the issue. It uses little or no quality (written) references, but this issue is balanced out with the number of expert interviews and direct quotes. Therefore, I thought it was nice to read, but I found nothing really provocative in there.

On the other hand, however, I find that it does a very good job as an introduction to the whole cyber conflict issue for non-specialist readers. If you need to convince your boss or your grandmother that cyber conflicts should be studied - have them read this report.

Review: Jose Nazario on Political DDoS Attacks

Time for another review. This time it is Jose Nazario's CWCON paper called "Politically Motivated Denial of Service Attacks." He is looking at DDoS as one of the more visible and popular cyber attack forms and is limiting his sample to the ones with a political motivation (vs the standard criminal motivation - money).

NOTE: The final published version of this paper was accepted after the conference so it includes some more recent examples.

His research is based on data from three sources: ATLAS project at Arbor Networks (basically, ATLAS collects data from sensors to provide an overview of the more visible cyber campaigns), infiltrated botnet C&C servers and border gateway protocol (BGP) routing data.

He starts out with a little overview of major political DDoS campaigns of the past, covering the following events:
  • 2001 Hainan Island incident
  • 2007 Estonia campaign
  • 2008 China v CNN campaign
  • 2008 Georgia campaign
  • 2008 Burma
  • 2007 elections in Russia
  • 2008 Radio Free Europe campaign
  • 2008 anti-NATO campaign in Ukraine
  • 2009 MSK forum DDoS in Kazakhstan
  • 2008 DDoS-censoring of Russian opposition websites
  • 2009 Israel v Gaza/Hamas
  • 2009 Kyrgyzstan - a false positive?
  • 2008 Kommersant DDoS
  • 2009 Kazakhstan opposition sites under DDoS
  • 2009 South Korean/US campaign
It is noticeable how most of these events are known by the target only. In history, conflicts are usually named after both/all participants or at least the participants are known. In cyber conflicts, however, it seems to be the norm that the aggressor remains anonymous. Even if all the circumstantial evidence and opinions point against one entity, rarely is there enough proof to attribute the attack in court.

He continues to describe the attacker type that seem to be behind most of the attacks listed. In general, the attackers are "classic right-wing" supporters of the government and targeting internal or external opposition. He also writes about using propaganda to recruit supporters for a cyber campaign and then training them online - a basic ad-hoc cyber militia. What the militia cannot achieve with finesse and expertise, they make up in numbers (DDoS).

He points out that the classical goals for such attacks are to punish the target, or to show dissent, or to censor the target (especially true for attacks against news outlets and opposition parties). He brings examples of partial attribution: Nashi youth group in Russia, the Chinese Honker Union and StopGeorgia.ru. Note that in all these cases the attackers made the claim - nothing has been proven in court (as far as I know).

He reviews some broad responses to the cyber campaigns listed and finishes with recommendations:
  • harness public support and international cooperation
  • deploy available commercial tools
  • be open to commercial offers to help
  • develop a more efficient decision making process
  • delegate authority
  • consensus is sometimes not necessary
In conclusion, he also points out that we need to study guerilla and asymmetric warfare in order to succeed on the cyber battlefield.

The paper has numerous examples from recent years and thus gives a good overview of the extent of the problem. However, the examples have different level of detail (often too vague) to be of much help on researching a specific case. I would have expected a more detailed analysis of a limited number of campaigns. As always, read the paper for full value.

Review: Billy Rios on Cyber Attacks

It has been a busy time since last post. I gave a short lecture at the NATO School in Germany last week and I'm preparing some paper ideas for next year. However, I decided to take a short breather and review another paper from the Conference on Cyber Warfare - Billy K. Rios wrote a piece titled "Sun-Tzu Was a Hacker: An Examination of the Tactics and Operations from a Real World Cyber Attack." His work is partially based on the Grey Goose Report I.

The paper tries to map some real cyber operations to equivalent concepts in maneuver warfare, particularly drawing on the Georgia case and the US Marine Corps doctrine. He starts out by describing the essence of maneuver warfare and points out that cyber operations cannot "win a war". Instead, they can break up the enemy's cohesion and allow for exploitation by other (conventional) means. Incidentally, the Chinese seem to have adopted the same idea.

Discussing decentralized command and commanders intent, he brings the example of how a target list of Georgian sites was posted in a forum without clear instructions for action. The forum members then contributed with potential attack plans/instructions and discussed the campaign. As a result, a variety of targets and options became available and the attackers could each choose a course of action suitable for their skill, resources and level of motivation. As a side note, similar behavior was observed a year earlier during the cyber campaign against Estonia.

As an example of combined arms, he brings the example of SQL injection queries for fingerprinting and gaining access to database contents (NB! starting a month before the armed conflict), exploiting this information for intelligence, preparing automated attack tools that are then provided through the forum to anyone interested. I think he could have used a better example, because the link to combined arms is not clearly apparent.

Illustrating the concept of initiative he uses the examples of pre-emtive intrusions to Georgian systems and the sustained pressure to keep initiative on the attacker side, while keeping the Georgians to react. As a result, responding to cyber attacks wasted valuable time.

He also explains the importance of identifying and attacking enemy Centres of Gravity, although he does not connect it to the Georgian case. The important point is that these centres need not be physical fortifications or units, but can also encompass things like morale and resolve. Clearly, cyber attacks are a potential way of attacking the enemy centres of gravity, especially C2 networks and information targets.

He then points out that conventional weapons have physical limitations and the skill of the operator can only have relatively little effect in terms of stretching the effective range, damage etc. For example, a skilled marksman with a M4 carbine can hit a target from several hundred meters with standard sights, but not much more. On the other hand, the cyber warrior's capability to do damage is directly correlated with his skills. I especially like this sentence:
"Creating an offensive cyber capability is less about finding the right hardware and more about finding the right people and skillsets."
He also highlights that it poses a problem for intelligence analysts, as it is very difficult to estimate or track the development of offensive cyber capability, because the key component is the skillset of operators, not the invested money or acquired hardware.

Rios summarizes the paper by emphasizing that
  • cyber capability should be incorporated into the overall plan, as it will not win the war on its own.
  • Command and Control should be kept decentralized and decisions delegated to the lowest level. [This is in contrast to the Chinese doctrine, which seems to prefer rigid central control and limited use of the cyber strikes. - RO]
  • the individual cyber specialist is the weapon system, not his laptop or his sidearm.
The paper is short and to the point. I like the summary, which brings out some good points (even some that do not seem apparent from the main text).

Review: Amit Sharma on Cyber Wars

Time for another review of the articles published in the proceedings of the CCD COE Cyber Warfare Conference. Next up is Amit Sharma from India, who wrote an interesting paper titled "Cyber Wars: A Paradigm Shift from means ot Ends".

He starts out by explaining the idea behind the paper. He hopes to provide a
"framework in which cyber warfare will have a strategic effect by acting as primary means to achieve conventional ends, hence will induce a paradigm shift from the conventional notion of cyber warfare as a tactical force multiplier to the notion of strategic cyber warfare acting as primary means of achieving grand strategic objectives in the contemporary world order. The author will accomplish this objective by deriving the elixir of Clausewitz’s Trinitarian warfare and applying the concepts of Rapid dominance and Parallel warfare in cyber space so as to generate the strategic paralytic effect envisaged in effect based warfare. The author will conclude by shattering the conventional dictum of cyber defence, based on the notion of “defence in layers” and legal aspects of Law of Armed Conflict; by providing the only feasible and viable cyber defence strategy relying on the application of Rational Deterrence Theory (RDT) in general and on the idea of Mutually Assured Destruction (MAD) in particular so as to maintain the strategic status quo."
A tall order by any standard. The paper is written in an artistic and forceful language, painting the scene of an apocalyptic cyber strike that ends all and paralyses the entire state from the government to the citizen by simultaneously disrupting the trinity of government, military and people. I think that this strong emphasis on total paralysis (and total war) is a potential weakness of his approach.

Even though all theoretical model are abstractions, I believe his trinity (imagine a triangle) model is somewhat idealistic and naive. His description of the people corner is exclusively oriented to the liberal western countries (which includes the minority of the world's population and, arguably, are not as liberal or democratic as they may portray themselves). What about the rest of the world? The model's military corner is focused on the network-centric digital troops, which again represent the minority (although a powerful one) in the militaries of the world and even that is not always as networked on the battleground as the doctrine would imply. Last, but not least, the government corner, where governments are charged to provide "a secure, secular and democratic environment" for the people. Well, let's try to name some big countries that fit that idealistic description to the letter in practice, as well as in theory. It won't be easy. So, the model applies in a theoretical ideal case and I agree that in such a case the implications can be extremely dangerous.

The danger comes from simultaneously taking down all three components of the trinity with a parallel cyber campaign, which, as we have just reviewed, is entirely dependent on the assumption that the country is wired beyond the point of safe return. He concedes that in most recent cyber conflicts this parallelism has not taken place and we have seen much more limited campaigns.

He then proceeds with a five step plan for a strategic cyber campaign: "Shape, Deter, Seize initiative, Dominate and Exit". This is a nice and clean model for describing a (cyber) conflict, but I disagree with some of his conclusions.

In discussing the deter stage, he touches on the concept of countervailing, or "making known to the potential adversary that the implication of a nuclear strike would be far greater than the potential gains an adversary can achieve by initiating the first strike." He mentions that the recent cyber attacks against Estonia, Georgia, UK, France etc. may be an example of cyber counterveiling. I do not see it that way, as a key point of countervailing relies on letting the enemy know your capability - and no state has taken responsibility for the attacks listed. Furthermore, the cases he cites are not traditional military conflicts (with the possible exception of the Georgia attacks), but merely harassment or espionage, which do not demonstrate the potential destructive capability of a state. They do serve as reminders that networks are vulnerable, however.

He does make a good point that in order to deter an attack you need a "Cyber Triad capability", which consists of
"Regular defence/military assets and networks, [...] isolated conglomerate of air-gapped networks situated across the friendly nations as part of cooperative defence, which can be initiated as credible second strike option; and [...] a loosely connected network of cyber militia involving patriotic hackers, commercial white hats and private contractors which can be initiated after the initial strike or in case of early warning of a potential strike."
He proceeds by demonstrating that the concept of defense in layers and the Law of Armed Conflict (LoAC) do not work in a strategic cyber campaign. I do not understand his point that a system built on the concept of defense in layers (defence-in-depth) is "as strong as its weakest link." To me, defense in layers means exactly the opposite - you can take out any single node and the system remains secure due to the other layers.

His other argument is that LoAC does not cover strategic cyber warfare. Granted, there have been no successful applications of LoAC to strategic cyber warfare yet, but that is because we have not yet seen a strategic cyber warfare campaign in the armed conflict sense. As mentioned above, we have plenty of hactivism, espionage and other examples that fall outside the LoAC framework, but no state-on-state wars where cyber has played a significant role. Therefore, it is premature to throw LoAC out of the window as it is today. However, I agree that it needs updating to meet modern scenarios and the CCD COE is among the experts that work toward this goal (some discussions on this took place at the Cyber Conflict Law and Policy Conference).

He finishes by arguing that Mutually Assured Destruction (MAD) doctrine is the best way to keep states from engaging in strategic cyber warfare. I would argue that MAD simply does not work well in cyberspace, as
  1. attribution of the cyber attack may be impossible,
  2. in case attribution can be achieved, there is a question of false-flag operations,
  3. in case a second strike is launched, there will be ample collateral damage to third states, which can escalate the conflict further,
  4. the cyber triad is never ideal and many (most) countries in the world today are almost invulnerable to strategic cyber warfare, because they have little or no reliance on cyberspace,
  5. in case a strategic cyber campaign succeeds against a modern military power, they can always retaliate with weapons of mass destruction (missile silos should be air-gapped from the rest of cyberspace, at least I would hope so).
Overall, the paper has a lot of provocative thoughts and arguments and I enjoyed reading it (what would be the point of reading things that do not raise a single question or counterargument). I have not covered some of his points that I agree with and, as always, I recommend reading the full paper. We met briefly at the Conference in June and discussed some of the points above, and in the end agreed to disagree on some of them. I wish him luck in his research, as he definitely rocks the boat.

Cyber Report on China

I got a tip to a new report on Chinese cyber capabilities [pdf] by Northrop Grumman. The report aims to provide "a comprehensive open source assessment of China’s capability to conduct computer network operations (CNO) both during peacetime and periods of conflict."

They start off with an overview of the strategic developments in China. Even though there is no official CNO strategy, the PLA is in fact preparing to fight the cyber battle. I found it interesting that they consider domination in cyber space a prerequisite for air and naval domination. This is a clear indication of its importance in the Chinese thinking. It also explains why the EW/IW/CW issue is seen as the forcing agent behind the "informationization" of the PLA.

Chinese writings identify enemy C4ISR and logistics systems as the primary targets in a military conflict and also point out that IW will fire the opening "shots" in a war. However, there is also indication that IW and conventional techniques can and should be used together for maximum effect. I think this is very important, because I have often seen the mindset that IW is something separate from "real" warfighting. Then again, the Chinese have thousands of years of experience to draw upon, so it is not surprising that they see the value of combining the two.

They also point out that China is very active in developing counter-space weapons (EW, CW, kinetic, directed energy, EMP etc.) in order to fight a potentially tech-heavy oriented opponent such as the US.

Another interesting aspect is targeting. Instead of trying to blanket the battlefield, the Chinese writings suggest taking out key nodes in order to provide opportunities for other forces to exploit the resulting confusion in a specific point in the battlefield. I believe this refers more towards EW and kinetic than cyber, as tactical use of cyber attacks would probably be difficult to implement.

It seems that the PLA is actively training to fight in conditions where CW/IW is a common part of the battle field, including special training centers and a designated Blue Force (OPFOR) regiment. In addition, several universities seem to engage in offensive CW research and education.

There is an interesting note about using EW/CW pre-emptively to deter an enemy or to limit the size of the conflict without much bloodshed. In fact, they seem to consider CW a deterrent second only to nuclear at the strategic level. I like the comment that CW is the PLAs longest range weapon.

Another key point that I agree with is that CNO is useful for damaging/degrading systems, but also for deploying PSYOPS/deception against enemy personnel, enemy supporters and the public in general. I have met some people who consider PR the one and only element of IW and I just disagree. With so many options available under IW, it would be irresponsible to overly limit yourself to use only one.

There is an excellent section about how the Chinese might use CNO against the US (military) in a conflict scenarion. I agree wholeheartedly that the logistics and C2 systems at the theater or higher level would be sensible targets to buy time for the PLA and to cause confusion among US forces. However, as I have noted before, the discussion here is limited to purely military targets (like in the US discussion), but in a total war the commercial sector may be the more important strategic target.

The following section gives a broad overview of what is publicly known about the Chinese CW structure. Of particular interest for me are the PLA IW militia units, which seem to be drafted from commercial and academic entities to supplement PLAs integral capabilities. The idea of using telcos and universities (for example) to create sub-units for the militia is perhaps not intuitive for the westerners, but it does make sense. You have people with the right skills, established relationships and access to networks and systems - all they need is a mission.

The second interesting bit is that some militia sub-units seem to focus purely on R&D. In order to understand the significance, consider if infantry (militia) battalion is likely to have a dedicated infantry tactics research and development platoon. This highlights the difference between the information warriors and the traditional fighters. The report also mentions discussions about setting a different standard (age limit, physical condition) for the cyber warrior, something that was also debated here.

Moving on to the independent Chinese (patriotic) hacker community, the report claims that around 2002-2004 the state reversed its previously favorable stance towards patriotic hactivism and as a result the movement has died down. This was not the notion I got in Stockholm in May, where Dr Xu Wu from Arizona State University talked about Chinese cyber nationalism. According to him, the patriotic hacker community is alive and well, albeit somewhat underground. He also claimed that the state was having difficulties deciding what to do with this resource, as it is difficult to control - something that I also predicted in my paper about volunteer cyber attackers. Dr Wu compared it to a double-edged sword, which can cut both ways. It is possible, however, that this discrepancy does not exist and the official cyber militias have incorporated a significant part of the patriotic hacker community.

The report then provides a couple of examples of recent attacks probably originating from China. There are also various examples of relations between the state and the hacker community, including state recruitment in the hacker forums. One of the more interesting examples is how a java language user group transformed into a patriotic hacker group over the EP-3 incident. This is an excellent illustration of how "cyber tribes" can very quickly develop into cyber militias.

In the following section, cyber espionage is investigated from the US perspective. The report points out that potential Chinese espionage efforts are a great concern for the US counter-intelligence community, especially in the light of the reactive cyber defense paradigms in place. They claim that there is a strong case for state-sponsored attacks, although it is often difficult to fully attribute the attack to a state.

The report includes a nice explanation of a targeted attack via e-mail to get access to the organization's systems. However, they include an even more interesting case study of a large data heist in a US firm. It provides a simple description of the time line and activities uncovered by the forensic team.

The report concludes with a comprehensive list of China-related cyber events between 1999 and 2009.

Overall, the report is easy to read and low-tech. It covers many interesting aspects of the Chinese cyber issues. However, since this is a public and open-source report, it does not go into too much detail and it may inadvertently include some deception information. All-in-all, I enjoyed it and it provided me with a lot of things to think about. It also confirms some of my own theories and thoughts.

As always, read the report for full detail.

Review: Analogies and Cyber Security

Here is a short review of the paper "What Analogies Can Tell Us About the Future of Cyber Security" by David Sulek and Ned Moran, published in the proceedings of the CCD COE Cyber Warfare Conference.

In the paper they explore the potential dangers that come with using colorful analogies like cyber Pearl Harbor, cyber Katrina, cyber 9/11 etc. In order to deal with these dangers they propose to start with developing a detailed issue history. A well written issue history helps determine which analogies apply. They give a short example in the form of the cyber issue history that, among other things, lists what is known, what is unclear and what is presumed about the topic.

They then provide a framework for exploring cyber analogies. It consists of two dimensions: one axis representing inspiration (hope and possibility) vs desperation (fear and danger) and the other systemic (evolution) vs disruptive (revolution). They give some examples for each: invention of the telegraph was an inspiring event, as it created new possibilities to communicate. On the other hand, the Y2K bug represented a potential danger to the computer systems. World War I was a linear, systemic result of military build-up, whereas 9/11 was a disruptive, revolutionary event. I think the first pair of examples is a good fit, but I am not so sure about the second. One could argue that there is an evolutionary line of developments that lead to both tragedies, we just haven't taken the time to really reflect on the reasons for, the facts of and the aftershocks of the 9/11 attacks. But I digress.

They spend the rest of the paper analyzing four cases from each quadrant of the model as a potential fit for cyber security. The four cases are the Strategic Defence Initiative (inspiration, evolution), the Cold War (desperation, evolution), the [US] National Highway System (inspiration, revolution) and finally, Pearl Harbor (desperation, revolution). Each case reveals interesting overlaps with cyber. However, each also has its discrepancies, so no clear match emerges.

They sum up their analysis in four points:
  1. There is no single analogy that works for cyber.
  2. Cases that balance inspiration and desperation leave the strongest impression on history.
  3. Many analogies used today are at the extreme ends of the model.
  4. It is important to build a good timeline for an issue, in order to understand the reasons for events.
Overall, it is a nice read and an interesting analysis of the four cases. I may not agree with the interpretation of historical events, but then again, the model is meant to be an abstract tool to describe analogies. As such, there will always be opportunities to interpret events in different ways.

The main point for me is to review the cyber analogies that I have used in the past. The analysis of the four cases has given me some food for thought and hopefully, next time I blurt out with something, I remember to also offer caveats.

As always, the paper itself is much more detailed and I recommend reading it in full.

Botnets and Proactive System Defense

I finally took the time to sit down again and read an article with the provocative title "Botnets and Proactive System Defense" (2008, Springer Link) by John Bambenek and Agnes Klus. From the title I assumed it would be about using botnets as weapons for a proactive defense strategy, but I was mistaken.

Instead, they start off with a nice survey on how commerce has moved to the web and why the old security measures no longer protect the consumers. They touch upon the problems with making transactions with credit card and social security numbers (basically, single factor authentication), as well as several other computer security issues like the reactive patch cycle. Next they review the growth and development of malware, using the Shadowserver graphs to illustrate their point. All this is not new, but it does a good job of surveying the problem.

Getting to more interesting bits, they propose that an ideal botnet strives to maximise six key properties: "high capacity, low overhead, fast responding, flexible, anonymifying [anonymizing?] and quiet." They show how IRC meets these requirements and point out that other technologies, such as RSS, will replace the IRC bot as more and more network administrators grow suspicious of IRC traffic.

For proactive defense, they consider offering the consumer free security software and encrypting their sensitive traffic. Another proposal is to switch from "allow all" to "deny all" or "deny most" principle in terms of antivirus software default settings for running programs. They assume that signing software would solve this problem, as
"There are a finite number of reputable software vendors and applications out there and far more disreputable software vendors and applications."
Not sure I agree with what this claim implies. You cannot have a complete list of "good guys" that will keep you safe from malware. If that were true, we could also say that there are a finite number of reputable ISP-s, so we can just drop all packets that come from the jungle. Unfortunately, this is not true in either case. Reputable businesses have engaged in malicious activity (Sony rootkit, for example) and a lot of cyber attacks come from the networks of reputable ISP's (by default, a potential malware victim would sign a contract with a "reputable" ISP to get access to the net).

One more proposal for making the defense more proactive is to enable remote security validation on computers. While this may sound good in theory and there are even ways of doing this, I do not see it passed into law or practice due to privacy concerns.

Finally, they point out that the great debate over the need for a national ID in US may be moot, as the social security number already acts as one, and a poor one at that.

They conclude by reiterating that the main strategy against botnets is to make them economically nonviable for the criminals. While a nice overview and an easy read, I did not find much new in the paper, however. What I did find is an interesting example of how parts of the US sometimes seem to lag behind in adopting technology:
"Banks already are starting ... requiring one-time passwords with keyring tokens or other devices so that even if an attacker gets the one-time password, they cannot compromise the account."
In many parts of the world, one-time passwords and passcode generators have been the norm for on-line banking for years. In Estonia, for example, the lowest level authentication still in use by the general banking sector uses a set of 20-30 randomly repeating passcodes. This is not safe, sure, and that is why the clients using this method have a ~300 USD daily transaction limit (the system itself is being phased out). If you want more, you need either a passcode generator or the national ID card with valid certificates. In both cases, you need to know something (pin) and have something in order to carry out your transaction.

"Where Computer Security Meets National Security"

I read an interesting article by Helen Nissenbaum, on "Where Computer Security Meets National Security" (2005) [pdf, Springer link] .

She starts with a good point that the "traditional" computer security, developed in the technical community and focused on the protection of a computer (system) is difficult to port into national security terms, where damage to life, economy, morale and reputation is the core worry. She argues that the "technical computer security" focuses primarily on ensuring confidentiality, integrity and availability, even though there is a push to extend this to ensuring overall "trustworthiness" of a computer system (including resilience etc.).

She calls the competing national security conception cyber security (a term that has grown more popular since then). According to her, cyber security is most concerned with three problems:
  • using computer networks "as a medium or staging ground for antisocial, disruptive, or dangerous organizations and communications." In other words, propaganda, phishing and a host of other soft threats;
  • using computer networks to attack the critical societal (information) infrastructure, or the hard threats; and
  • using computer networks against computer networks. I may misunderstand her reasoning, but I think computer networks in the larger sense (Internet infrastructure, SCADA systems, public services on the internet) are also part of the critical information infrastructure, and I would combine the last two categories into one.
I found it interesting that she illustrates how computer security can be used in various moral (protect users from harm) and immoral ways (protect the interests of the company, while limiting the usefulness of the product to the end user).

She then reviews the concept of "securitization" by the Copenhagen School. Essentially, it means that unlike "realist" methods, there are more threats than just military aggression and there are more targets as well (state + religion, economy, environment etc.). Furthermore, securitization is a process of making something into a security issue (especially in the eyes of the public). In her words: "In general, to securitize an activity or state-of affairs is to present it as an urgent, imminent, extensive, and existential threat to a significant collective."
[Note: An interesting concept and something to be studied later.]

The next chapter shows some steps how cyber security has been securitized, including a funny interlude about how the music and film industry is trying to securitize the P2P threat against their obsolete business model. She also covers some examples of cyber space shown as a potential battle space and it's asymmetric nature.

Getting to the meat of the issue, she compares the two approaches:
  • Computer security recognizes a broad range of the degree and type of harm, while the cyber security assumes that the threats are dire or existential.
  • Computer security focuses on protecting the "individual nodes" (people, computers), while cyber security looks at "collective security."
  • Computer security rests on the moral foundation of protecting from harm, while the moral aspects of cyber security can vary depending on the securitization process.
An important question she brings up is when is securitization warranted? When is a threat dire enough to become a national security issue that is handled in secrecy, and potentially in ways not common to a democratic state? She argues that there is lack of reliable data on the size of the threat from the computer security perspective, as research is focused on (potential) vulnerabilities, while reporting of actual incidents is hap-hazard at best. She also touches on the issue that the same attack can be viewed in many different contexts (criminal, national defence, activism etc.).

She concludes that in the end, the "technical computer security" approach might be better, as it provides security at the user level and thus still allows us to use the net for the core purpose of sharing information and ideas. The highly securitized state controlled approach, on the other hand, raises questions about privacy, freedom of speech etc.

To sum up, a very interesting article with much food for thought. I found several interesting insights here and I am sure that more will pop up later. If anything caught your eye, I recommend reading the article in full, as there are many details that I did not cover.

Cyber Conflict Law and Policy Conference

As mentioned earlier, I attended the Cyber Conflict Law and Policy Conference in Tallinn last week. The event was organized by the CCD COE and took place in Swissotel from 9-11 September. About 150 attendees from about two dozen countries discussed issues like the applicability of the Law of Armed Conflict, legal frameworks etc. I will try to briefly summarize by sessions.

Setting the Stage

The conference opened with a keynote speech by the President of Estonia, Mr Toomas Hendrik Ilves. He stressed the need to adapt the defense thinking (including legal frameworks) to the changes in technology. He illustrated the point with medieval defensive structures in Tallinn, which were useless in fending off air raids during WWII. He also talked about the need for collective cyber defence. An important idea was that in NATO, as far as cyber defence is concerned, we should focus more on Article 4 (consultation among nations) today, so that if and when Article 5 (collective self-defence) is ever needed, there is already some consensus.

Next speaker was MG Glynne Hines, Director of NATO HQ C3 Staff. He pointed out the need for consistent legal advice and the usefulness of embedding lawyers in a cyber defence organization. He alsp briefly touched upon some changes in NATO that were initiated by the lessons learned from the 2007 cyber attacks against Estonia: adoption of NATO cyber defence policy and concept, accelerated development of NCIRC and the NATO cyber defence exercise.

Ms Eneken Tikk of the CCD COE, the content organizer for the conference, introduced a draft Framework for International Cyber Security (FICS), which was developed in cooperation with George Mason University Center for Infrastructure Protection (GMU CIP). Basically, they are a collection of abstract models/slides that should be helpful in reaching a common understanding about the issue.

Country Reports on Cyber Security Strategy

Ms Heli Tiirmaa-Klaar from Estonian MoD gave a brief overview of the 2007 April-May events, as well as the pervasiveness of e-services in Estonia. She then proceeded to introduce the Estonian Cyber Security Strategy. Some more points from her talk: cyber attacks pose a new asymmetric threat against critical infrastructure and the development of cyber defence capabilities is very uneven across different states.

Dr Per Oscarson from the Swedish Civil Contingencies Agency gave an overview about his organisation and the Swedish approach to national cyber security. It seems the Swedes have at least in theory a model for planning cyber security, consisting of two main parts: the strategy (vision and strategic directions) and the action plan (explicit objectives and measures).

WCDR Adrian Frost from UK MoD proceeded by giving a quick overview of the British approach. Apparently, UK considers cyber as one of the five domains (air, land, sea, space and cyber), similar to some thoughts I have heard from USAF in recent years. He briefly introduced the UK Cyber Security Strategy (approved 23 June), which aims to secure UK advantage in cyberspace by reducing risk (public), exploiting opportunities (industry) and improving knowledge, capabilities and decision-making (international).

Autopsy of a Cyber Conflict

Professor Daniel Ryan from the US National Defense University gave an interesting talk about the lawyer's look at a cyber incident. Specifically, he addressed the issue that there are regular incidents (handled as per SOP or ignored) and then there are INCIDENTs that really matter. In the latter case, one needs to determine if it is an attack (or accident, technical failure etc.), who is behind the attack (attribution) and who can/should respond to the attack (law enforcement, intelligence, military, lawyers).

Next, Dr Bret Michael from the US Naval Postgraduate School addressed various cyber conflict issues from a more technical viewpoint. Among his points was the claim that cloud computing will change the way we work and will introduce new security challenges. An interesting thought was the martial arts analogy - in cyber defence we should not focus on rigid and forceful response (karate), but rely more on the flexibility and use of the opponent's strength (aikido).

Unfortunately I had to leave early that day and I didn't catch Mr Joe Weiss' (Industry Expert and Control Systems) talk on industrial control systems, but I heard that he gave an insightful presentation on the vulnerabilities associated with the systems that uphold modern society.

Cyber Security Institutionalized - Pieces of an Effective Defence Model

The second day started with Ms Eneken Tikk's talk on international organization's legal and policy approaches to cyber incidents. Sha listed the numerous laws, regulations and directives that various IOs have produced to deal with cyber security matters. To limit the scope, she briefly examined the documents that focus on data protection and concluded that while there are a lot of regulations in place, they tend to be stovepiped and there is not enough practice in using the breadth of tools available. She also discussed the different approaches that have been taken in various EU countries on data protection.

Ms Yurie Ito from ICANN, formerly of JP-CERT gave a presentation about recent developments in ICANN, with regard to security. Unfortunately she did not have enough time to delve deeper into her slides on Conficker, as I am sure her insight would have been valuable.

Ms Maeve Dion from GMU CIP addressed public-private partnerships and national input to international cyber security. She touched various points, including the many areas of law that deal with aspects of cyber, informal vs formal networks in cyber defence, developing strategy and risk analysis methodologies.

The day ended with three working groups that discussed FICS and cyber law/policy issues.

Enhanced FICS

The final day started with Professor Derek Jinks from US Naval War College. His talk was on the Law of Armed Conflict (LoAC) and the military perspective. He pointed out that LoAC is not there to minimize "war" as an official status of affairs, but to minimize organized violence. Another good point was that "armed" does not imply any physical properties or mechanics, but rather organized application of violence. He further explored the concept of armed attack, as it is often used in the definition of armed conflict. He noted that armed attack is subject to various conditions, such as severity (death or substantial destruction of property), status of the attacker (according to UN terms, attacker is state, but in practice it is often a non-state actor that may or may not have state sponsorship), status of the target (again, old rules dictate the state as target, whereas in practice, any entity that the state can claim sovereignty over, incl. citizens), necessity, proportionality, time-proximity etc. He also raised some interesting questions about new concepts like cyber occupation (displacing civil authority by means of cyber attacks). A very good talk indeed, even though he did not have enough time to go into all the details.

Next came Dr Thomas Ramsauer from German Ministry of Interior. His talk focused on the law enforcement perspective, but he also revisited some LoAC questions. He used a nice model of cyber conflicts, where you have the damage to target on one axis and organization of the attackers on the other. Then, as damage and level of organization increase, one progresses from cyber crime to cyber terrorism to cyber war. While I don't think it is that simple, it is a nice and visual way of presenting the idea. He also briefly touched the Schmitt test and the concept of attributing "private attacks" to a state actor. An interesting thought was that in order to limit collateral damage to civilians, commanders in future wars may be obliged to prefer cyber attacks over traditional means of warfare.

Mr Lauri Almann from Aare Raig Attorneys-at-Law (former undersecretary of defence of Estonia) gave a talk on national defence law from the government perspective. He focused on factors of decision making, which consisted of four one-dimensional axis': secret-public, fast-slow, international-national and professional-emotional. He proposed that in cyber conflicts, the first of all these pairs is the relevant (used) property. I am not sure I agree. Secrecy in international environments seems to exlude the fast property and often the professional property as well. He closed by noting that there is not much need to exercise the technical community (as they perform the cyber defence mission daily), but educate and train the legal and political community, who only get involved when things get hot [and potentially profitable - author's note].

Professor Lilian Edwards from University of Sheffield provided a brief glimpse into the information society law and the user perspective. She noted that laws should always set a balance between security and privacy. The problems appear when the balance varies from law to law and over different jurisdictions.

The conference ended by comments of the observers as well as summaries of the working group results. A couple of points that stuck were the slide on the spectrum of state-sponsorship by Jason Healey (US Cyber Conflict Studies Association) and the idea that some sort of International Cyber Tribunal may be needed [not sure how much success other international tribunals have had].

Finally, Mr John Bumgarner from the US Cyber Consequences Unit gave a short overview of their recent report on the lessons learned from the Georgia cyber attacks in 2008. Unfortunately, the report is not public, so his notes were fairly general and added little new insight to the events in Georgia. It's a shame, as he possesses a wealth of knowledge on the subject. I understand his position, but it is yet another example of classification issues diminishing the value of research.

Disclaimer: I hope I did not do injustice to anyone by misunderstanding or missing key issues in their talk.

Overall, the conference was a success and I am looking forward to the next one. I had the chance to talk to many interesting people on the sidelines and I also met some old friends. The cyber scene is very small indeed.

Evgeny Morozov on Cyber Myths

Evgeny Morozov of the Open Society Institute has an interesting essay in the Boston Review about myths in cyberspace. Specifically, he addresses the scaremongering and vague threat information that is used to get access to funding, fame or power.

He points out many official statements that exaggerate the threat from cyber terrorism and cyber war and asks the question: is there any evidence to back up these claims? No, at least not in the public realm. He also makes a point that the threat from the net information is produced by intelligence/defence organizations and information security companies that benefit from the increased funding. I think he is right in the sense that there are very few facts available, so we are left with hypotheses and conjecture. Honestly, I am partly to blame, as I have presented similar worst case scenarios in numerous conferences, in order to raise awareness of the topic.

He also touches the foggy quagmire that is the international legal definition of cyber warfare and what, if anything can and should be done if one breaks out. I think we will not have a clear answer on this in the near future, but at least the topic is also addressed by professionals.

In terms of how useful cyber attacks are for the military, Morozov refers the opinion that superpowers do not need cyber power, as they have more conventional means to crush the enemy. While that may be true, the question of attribution once again comes up - who will the superpower nuke, if they cannot identify the source of the cyber attack?

On the other hand, his conclusion that we should focus more on the threats from cyber crime and cyber-espionage is correct. However, it is not correct because cyber war is improbable, but because the tools used in cyber war will be very similar to the ones used in crime and espionage. The same piece of malware can be used to steal your personal data, collect intelligence on your organization or to disrupt your networks in preparation for a war. Thus, better defense against crimeware will also mean better defense in war.

A comment on Estonia

Unfortunately, Morozov uses unclear wording that may suggest that Estonia was off-line for nearly a month in 2007. It would be more correct to say that Estonia was under attack for about three weeks in 2007, but only a few critical on-line services (like banks) were affected for clients inside Estonia. One of the options, a white-list based "island Estonia" defence meant that the vast majority of the attacks could be easily blocked while maintaining service to the vast majority of the clients. As a result, clients of the two biggest banks in Estonia saw only a 45-90 minute interruption of service at the start of the attacks and that only affected the web interface of the banks. What is worrying, however, that these were critical "civilian" targets in a political conflict.

Sure, non-critical services (public government websites and news sites, for example) did suffer longer service outages due to cyber attacks (mostly simple DDoS), but in my opinion this was not a big issue for the state as a whole. The biggest effect would be potential information blockade, as local news sites or press sites are off-line, but that can easily be remedied by using other means of communication to push the message out (remember, e-mail works, phones work, faxes work, radio and TV are still on air, and even the postman makes his rounds). I personally had no problems communicating with friends and colleagues abroad throughout the period.
