PC/DACS is a subsystem not a complete trusted computer system. Therefore, it was evaluated against the Computer Security Subsystem Interpretation (CSSI). Specifically, the applicable requirements for this evaluation included identification and authentication (I and A), discretionary access control (DAC), audit and object reuse. PC/DACS runs on an IBM, PC, XT or AT or 100% BIOS compatible microcomputer with at least 512KB of random access memory (RAM) running MS-DOS or PC-DOS 2.0 or greater. The system is required to have at least one floppy disk drive, a hard disk drive and a monitor. PC/DACS is intended for environments where several users share a single personal computer. 收起
