Pentagon develops cyber arsenals

The Pentagon has developed a list of cyber-weapons and tools, including viruses that can sabotage an adversary’s critical networks, to streamline how the United States engages in computer warfare.

The classified list of capabilities has been in use for several months and has been approved by other agencies, including the CIA, said military officials who spoke on the condition of anonymity to describe a sensitive program.

The list forms part of the Pentagon’s set of approved weapons or “fires” that can be employed against an enemy.

“So whether it’s a tank, an M-16 or a computer virus, it’s going to follow the same rules so that we can understand how to employ it, when you can use it, when you can’t, what you can and can’t use,” a senior military official said.

The integration of cyber-technologies into a formal structure of approved capabilities is perhaps the most significant operational development in military cyber-doctrine in years, the senior military official said.

The framework clarifies, for instance, that the military needs presidential authorisation to penetrate a foreign computer network and leave a cyber-virus that can be activated later.

The military does not need such approval, however, to penetrate foreign networks for a variety of other activities. These include studying the cyber-capabilities of adversaries or examining how power plants or other networks operate. Military cyber-warriors can also, without presidential authorisation, leave beacons to mark spots for later targeting by viruses, the official said.

One example of a cyber-weapon is the Stuxnet worm that disrupted operations at an Iranian nuclear facility last year. U.S. officials have not acknowledged creating the computer worm, but many experts say they believe they had a role.

Under the new framework, the use of a weapon such as Stuxnet could occur only if the president granted approval, even if it were used during a state of hostilities, military officials said. The use of any cyber-weapon would have to be proportional to the threat, not inflict undue collateral damage and avoid civilian casualties.

The new framework comes as the Pentagon prepares to release a cyber-strategy that focuses largely on defence, the official said. It does not make a declaratory statement about what constitutes an act of war or use of force in cyberspace.

Instead, it seeks to clarify, among other things, that the United States need not respond to a cyber-attack in kind but may use traditional force instead as long as it is proportional. Nonetheless, another U.S. official acknowledged that “the United States is actively developing and implementing” cyber-capabilities “to deter or deny a potential adversary the ability to use its computer systems” to attack the US.

In general, under the framework, the use of any cyber-weapon outside an area of hostility or when the United States is not at war is called “direct action” and requires presidential approval, the senior military official said.
