Cybersecurity Leader of the Year
Diane Phan has been a long-time member of the DISA security team, serving now as chief of the Cyber Defense Division and program manager for the Endpoint Security Solutions Portfolio. Working for 10 years on endpoint security, she has been involved in implementing policy and technical changes to how the DOD’s mobile, desktop and other endpoints are secured. Some of the policy and technical changes she has helped lead are new tools that help to identify the networks devices are on and what vulnerabilities there are. “We have to ensure we have the ability to respond to threats and remediate threats in a timely manner,” she told an audience last year, speaking about the endpoint security changes she was leading.
