Mark Hakun, Deputy CISO at the Department of Defense (DoD), retired late last month after 34 years of working in both military and Federal civilian capacities, according to a LinkedIn posting by John Sherman, chief information officer at DoD.
“It was my privilege today to honor Deputy DoD CISO Mark Hakun, who is retiring after 34 years of combined military and civilian service,” said Sherman. “Mark is a top cybersecurity professional who has made great impacts in the IC and DoD, and I can’t wait to see what he’s going to accomplish in the next phase of his career.”
According to his LinkedIn account, Hakun “oversaw the coordination of cybersecurity standards, policies and procedures with other federal agencies, coalition partners and industry.”
Prior to working at the DoD, Hakun served at the National Security Agency where he worked as the Deputy Chief Information Officer for two years, as well as a project manager for 10 years.
He also worked as a program director at the Defense Information Systems Agency, where he had overseen developing National Background Investigation Services capabilities to replace legacy systems.
Hakun has a Bachelor of Science from the United States Naval Academy and a Master of Science from the Naval Postgraduate school.
