Washington, D.C., United States—The Pentagon is about to offer its cyberwarfare technology and capabilities to the service of its NATO allies.

U.S. Defense Secretary Jim Mattis is expected to make the announcement after a meeting with his NATO colleagues later in the week. The decision follows an agreement reached during a NATO summit in the summer. In July, NATO members had agreed to utilize one another’s cyberwarfare capabilities as a way to defend against network cyber attacks.

France, Germany, Spain, the UK, and the US have been some of the NATO members who have had to deal with cyber attacks in the past years. Russia has been the main suspect or perpetrator behind the attacks. Russian hackers and trolls interfered in the US and French presidential elections and in the Brexit, Scottish and Catalonia independence referenda.

“Russia is constantly pushing its cyber and information operations,” said Katie Wheelbarger, a Senior Pentagon official.

According to Pentagon officials, the US will maintain control over the cyberwarfare units and capabilities.

The intent behind the decision is for America’s cyberwarfare capabilities to serve as a deterrent, much like its nuclear armory serves.

Only recently, the Pentagon published its new cyberwarfare and cybersecurity strategy. It names Russia and China as the most important threats. It accuses the former of attempting to “influence our population and challenge our diplomatic processes.”  As far as China, the Pentagon claims that Chinese hackers consistently steal public and private sector data to gain economic superiority.

The strategy also commits to a more aggressive posture from here onward.
