Digital Equipment Corporation VAX/VMS Version 4.3
Abstract
The security protection provided by Digital Equipment Corporation's VAX/VMS Version 4.3 operating system has been evaluated by the National Computer Security Center (NCSC). The NCSC evaluation team has determined that the highest class at which VAX/VMS satisfies all the specified requirements of the Trusted Computer System Evaluation Criteria is class C2, and therefore has been assigned a class C2 rating by the NCSC. A system that has been evaluated as being a class C2 system provides a Trusted Computing Base (TCB) that enforces discretionary access control and, through the use of audit capabilities, accountability for the actions users initiate. VAX/VMS provides hardware based protection through a hierarchical four mode protection scheme. This, in conjunction with its virtual memory protection capability, provides process separation. The Access Control List (ACL) mechanism provides discretionary access control.
