"The Department of Defense Computer Security Center (DoDCSC) was established in January 1981 to encourage the widespread availability of trusted computer systems for use by facilities processing classified or other sensitive data. In the second quarter of FY83, CGA Software Products Group, Inc. requested that the DoDCSC evaluate Version 3.0 of their commercially available TOP SECRET security package for the OS/VS2 MVS [Multiple Virtual Storage] operating system. MVS is an IBM operating system for its 303X, 308X, 4341, 370/158 and 370/168 processors. The security features provided by Version 3.0 of TOP SECRET were evaluated against the requirements specified by the Department of Defense trusted Computer System Evaluation Criteria dated 15 August 1983."
