Control Data Corporation Network Operating System Security Evaluation Package

Abstract

The security protection provided by Control Data Corporation's (CDC ) Network Operating System (NOS) Security Evaluation Package running on CDC CYBER 170 mode compatible machines has been evaluated by the National Computer Security Center (NCSC). The security features of NOS were evaluated against the requirements specified by the Department of Defense Trusted Computer System Evaluation Criteria (the Criteria) dated August 1983. This report presents the findings of the evaluation. The NCSC evaluation team has determined that the highest at which NOS satisfies all the specified requirements of the Criteria is class C2, and therefore NOS has been assigned a class C2 rating. Additionally, NOS provides some mandatory access controls that, while not sufficient to satisfy the Criteria's B1 mandatory access control and labeling requirements, do provide some of the mechanisms needed when handling classified or non-classified but sensitive information. Keywords: Computer programs; Test and evaluation; CDC; NOS; C2; NCSC; Evaluated product list; Trusted computer system evaluation criteria.
