A new Zero Trust Portfolio Management Office is putting the Defense Department on track to improve its overall cybersecurity posture. While this will be a major task for DOD, a zero-trust roadmap will ensure the proper training and workforce are in place for greater interoperability across the entire department. The portfolio management office will also help accelerate the adoption of zero trust throughout DOD and make it an embedded way of life. DOD’s Principal Deputy CIO for Cybersecurity Mark Hakun talks about culture change and the integration of zero trust, the challenges the department is facing and the capabilities DOD hopes to deliver later this year.
