Cybersecurity

The Cybersecurity Subcommittee is a specialized division of the Senate Armed Services Committee focused exclusively on military cyber policy and operations. As a subcommittee, it conducts initial hearings and reviews legislation within its narrow jurisdiction before matters proceed to the full Armed Services Committee, which alone can report bills to the Senate floor. This structure allows the subcommittee to develop deep expertise in a complex policy area while the parent committee maintains final legislative authority.

The subcommittee has primary jurisdiction over all policies and programs related to military cyber forces and capabilities. It oversees the United States Cyber Command and the cyber components of other Department of Defense commands and agencies. This includes both defensive measures to protect military networks and offensive cyber capabilities. The subcommittee also reviews budget accounts and personnel matters related to military cybersecurity operations.

Chaired by Senator Mike Rounds of South Dakota, with Senator Jacky Rosen of Nevada as Ranking Member, the subcommittee comprises 11 members. Recent hearings have examined critical topics including the Department's cyber force generation plan, artificial intelligence applications in cyber operations, defense of military information networks, and the posture of U.S. Cyber Command. These hearings typically feature testimony from the Assistant Secretary of Defense for Cyber Policy, senior military commanders, and other defense officials responsible for the nation's military cyber operations.
