Abstract:

The security protection provided by release 1.0 of the Gould UTX32S operating system running on a Gould PowerNode processor has been evaluated by the National Computer Security Center NCSC. The NCSC evaluation team has determined that the highest class at which UTX32S satisfies all the specified requirements of the Criteria is class C2 and therefore, Release 1.0 of UTX32S has been assigned a class C2 rating. A system that has been rated as being a class C2 system provides a Trusted Computing Base TCB that enforces discretionary access control protection and, through the inclusion of audit capabilities, accountability of subjects for the actions they initiate. The UTX 32S operating system is a general-purpose, time-sharing system that provides two basic security mechanisms. The restricted environment provides separation between administrative and normal users and files. The protection bit mechanism provides discretionary access control.
