Oral History

Dr. Roger R. Schell, a retired U.S. Air Force Colonel and current president of Æsec Corporation, is one of the foremost contributors to and authorities on "high assurance" computer security. In this oral history he discusses his formulation of the secure kernel and reference monitor concepts (in the early 1970s), his work that led to security enhancements to Honeywell-Multics (mid-1970s), his role as deputy director of the National Computer Security Center (including leadership on TCSEC or “The Orange Book” in the early to mid-1980s), and commercial (high assurance) computer security enterprises he’s led since retiring from the Air Force. This material is based upon work supported by the National Science Foundation under Grant No. 1116862, “Building an Infrastructure for Computer Security History.”
