Computer Security Discourse at RAND, SDC, and NSA (1958–1970)

The 1967 Spring Joint Computer Conference session organized by Willis Ware and the 1970 Ware Report are widely held by computer security practitioners and historians to have defined the field’s origin. This article documents, describes, and assesses new evidence about two early multilevel access, time-sharing systems, SDC’s Q-32 and NSA’s RYE, and outlines the security-related consequences for both the 1967 SJCC session and 1970 Ware report.
