The U.S. Department of War (DoW) has appointed James “Aaron” Bishop as Deputy Chief Information Officer (Cybersecurity) and Chief Information Security Officer (DCIO(CS)-CISO). In this role, Bishop provides policy, technical, program, and department-wide oversight on all cybersecurity matters, supporting the DoW CIO in advancing Secretary Hegseth’s priorities for lethality, efficiency, and warfighter readiness.

Bishop assumed the responsibilities of Acting DoW CISO on February 27, succeeding David McKeown, who is departing government service after more than 40 years. He is a recognized National Security and Information Security Executive, having founded Eigenspace and Quantum Security Alliance to advance transformational research in cybersecurity while building partnerships across academia, industry, and government.

Additionally, Bishop held senior leadership roles at Science Applications International Corporation, Microsoft Corporation’s National Security Group, Keane Federal Systems, and ANSTEC, Inc. He is a veteran of the U.S. Navy.

“Mr. Bishop brings an extensive and unique blend of industry, federal, and transformational experience that will be critical as the Department focuses on Secretary Hegseth’s charge for lethality, efficiency, and warfighter readiness,” the Office of the DoW CIO said in a LinkedIn post announcing his appointment.
