Security-evaluated operating system

From Wikipedia, the free encyclopedia

In computing, security-evaluated operating systems have achieved certification from an external security-auditing organization, such as a B2 or A1 CSC-STD-001-83 "Department of Defense Trusted Computer System Evaluation Criteria" or Common Criteria (CC) certification.

Certificates do not endorse the "goodness" of an IT product by any organization that recognizes or gives effect to the certificate. A certificate represents the successful completion of a validation that a product met CC requirements for which it was evaluated/tested.

Note that certification applies to a particular configuration of the system running on a certain set of hardware; the certificate is only valid for this specific configuration, and does not extend to the same software if any aspect of the installation varies in any way. Often these scenarios are extremely limited compared to the normal environments in which computer operating systems usually run.

Trusted Solaris

Trusted Solaris is a security-focused version of the Solaris Unix operating system. Aimed primarily at the government computing sector, Trusted Solaris adds detailed auditing of all tasks, pluggable authentication, mandatory access control, additional physical authentication devices, and fine-grained access control(FGAC). Versions of Trusted Solaris through version 8 are Common Criteria certified. See and Trusted Solaris Version 8 received the EAL4 certification level augmented by a number of protection profiles. See for explanation of The Evaluation Assurance Levels.
