On offensive operations in cyberspace

This year started out in full gear for me and it seems that this is the first week where I can take a breath and write down some of my thoughts.

Last week I was invited to give a talk at one of many cyber defence/IA related conferences in Europe. As is often the case, the question of offensive cyber operations came up. It seems that whenever this happens, the automatic (and politically correct) answer is: well, the military can't plan an offensive cyber campaign, because most likely they will not be able to identify the actor behind the incoming cyber attacks (the attribution problem). They are right, counterattacks in cyberspace can be tricky.

However, this misses the point completely. Who says that cyber operations have to be symmetric (targeting only cyber aggressors with cyber ops). There is every reason for the military to plan and prepare offensive cyber operations for various military situations. When a military is deployed to fight someone, then the target should already be identified and is not necessarily limited to cyber operatives.

It makes sense to consider different ways to achieve a military objective: aerial bombardment, naval blockade, precision drone strikes, landing a division of Marines, cutting off C2 with cyber attacks, jamming radio communication with EW, threatening with nukes, etc. In fact, according to the principle of least harm, it is consceivable that the commander should FAVOR cyber attacks over more lethal options, if the end result is the same.

There is no good reason to limit the options of the commanders in the doctrine-writing phase between conflicts. Sure, there are legal issues, attribution issues, collateral damage issues and so on - as is the case with drone strikes, for example. And yet the drones are in the sky today. It just shows that where there is a will, there is also a way.

The only real counterargument for offensive cyber is that we don't want to see it on the battlefield (like nukes, bio and chem). However, clearly this is a Genie that we cannot force back into a bottle. Potential adversaries, both state and non-state are already using cyber attacks on a daily basis. Therefore, it makes sense to include this option in the play book of the commanders of the future.

It should be noted that I am not advocating military use of cyber attacks on a daily basis, but only in conflict situations and against "legal" targets. I am also aware that the whole "legal" issue is far from solved and most likely will not be solved in any reasonable timeframe.

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).
