The Defense Department’s chief information officer acts as a principal advisor to the secretary of defense in areas including IT, information management and telecom. Government Matters’ Mimi Geerges spoke with John Sherman, DoD CIO and acting chief digital and AI officer, about goals and challenges.
- “As CIO, with that hat on, cybersecurity is my absolute top priority,” said Sherman. He said his organization aims to be a federal leader in the paradigm shift towards zero trust.

- Sherman said his office is helping enable Joint All-Domain Command and Control (JADC2) and has coordinated remote work capabilities across the enterprise.
- He said the chief digital and AI officer role was created to provide decision advantage to everyone from the secretary of defense to battlefield leaders using data, advanced analytics and digital capabilities and to break down institutional barriers.
