The interview focuses on McLean’s long tenure at the Naval Research Laboratory (NRL)—serving as a scientist, supervisory scientist, and later, as a senior administrator (Superintendent of the Information Technology Division of NRL). Among other topics, McLean discusses his collaboration with Carl Landwehr and Constance Heitmeyer on a security model for the Military Message Systems, his (System Z) counterexample that challenged a premise of the Bell-LaPadula security model, the origins of the Foundations Workshop, and managerial roles at NRL.
