Trusted operating system
Trusted Operating System (TOS) generally refers to an operating system that provides sufficient support for multilevel security and evidence of correctness to meet a particular set of government requirements. The most common set of criteria for trusted operating system design is the Common Criteria combined with the Security Functional Requirements (SFRs) for Labeled Security Protection Profile (LSPP) and mandatory access control (MAC). The Common Criteria is the result of a multi-year effort by the governments of the U.S., Canada, United Kingdom, France, Germany, the Netherlands and other countries[1] to develop a harmonized security criteria for IT products.
Examples
Examples of certified trusted operating systems are:
- Apple Mac OS X 10.6 (Rated EAL 3+[2])
- HP-UX 11i v3 (Rated EAL 4+)
- Some Linux distributions (Rated up to EAL 4+)
- Microsoft Windows 7 and Microsoft Server 2008 R2 (Rated EAL 4+[3])
- AIX 5L with PitBull Foundation (Rated EAL 4+[4])
- Trusted Solaris
- Trusted UNICOS 8.0 (Rated B1[5])
- XTS-400 (Rated EAL5+[6])
- IBM VM (SP, BSE, HPO, XA, ESA, etc.) with RACF
Examples of operating systems that might be certifiable are:
