ARCYBER expanding use of AI agents for network operations

Army Cyber Command is upping its use of AI for network operations, according to top service officials, expanding the number of work roles that AI agents are assigned to and teasing upcoming contracts expected to reshape the way service uses the technology in cyberspace.

Lt. Gen. Christopher Eubank, the head of ARCYBER, said Monday at the annual AUSA conference in Washington, D.C., that a team his command established earlier this year has continued to develop AI cyber agents, giving them additional responsibilities and allowing them to work in the Army’s portion of the Department of Defense Information Network (DODIN).

Task Force Lexington, which ARCYBER stood up in April, started developing a handful of cyber work roles that AI agents would tackle, such as exploitation analysts and data engineers. Now, he said, they’ve “mapped out” an entire Cyber Protection Team composed of agents, including for analytic support and network analysts, among other roles.

“The task force has built those out. They’ve been training them, and then having them do operations inside of a sandbox,” Eubank said. He added that humans oversee the agents’ actions, retrain them and then have let the agents work inside the Army’s network “over time.”
