Limiting Access to the Trusted Computing Base

The term trusted computing base (or TCB) refers to the part of the Trusted Solaris environment that affects security; it includes software, hardware, firmware, documentation, and administrative procedures. Utility programs and application programs that can access security-related files are all part of the trusted computing base. Your administrator sets limits on all potential interactions that you can make with the TCB regarding programs that you need to do your job, files that you are allowed to access, and utility programs that can affect security.
