James “Aaron” Bishop has been tapped to serve as the Pentagon’s chief information security officer and deputy CIO for cybersecurity, the department announced on social media Thursday.
He assumed the role of CISO in an acting capacity on Feb. 27, according to a LinkedIn post from the Office of the Chief Information Officer.
In his new position, he’ll work under DOD CIO Kirsten Davies and be responsible for providing policy, technical, program and oversight support to the CIO on all cybersecurity matters.
Bishop previously served as CISO for the Department of the Air Force, which includes the Air and Space Forces.
According to his Air Force bio, his prior jobs in the private sector included CEO and founder of the Quantum Security Alliance, CEO and founder of Eigenspace, vice president and CISO for Science Applications International Corporation, and general manager of Microsoft’s National Security Group, among other roles.
Bishop “brings an extensive and unique blend of industry, federal, and transformational experience that will be critical as the Department focuses on Secretary [Pete] Hegseth’s charge for lethality, efficiency, and warfighter readiness,” the Pentagon CIO’s office posted on social media.
David McKeown, who previously served as the department’s CISO, deputy CIO for cybersecurity and special assistant for cybersecurity innovation, plans to leave government service for the private sector, according to the announcement.
