Access to the Trusted Computing Base Is Limited

The term trusted computing base (TCB) refers to the part of the Trusted Extensions software that handles events that are relevant to security. The TCB includes software, hardware, firmware, documentation, and administrative procedures. Utilities and application programs that can access security-related files are all part of the TCB. Your administrator sets limits on all potential interactions that you can have with the TCB. Such interactions include programs that you need to perform your job, files that you are allowed to access, and utilities that can affect security.
