Weegy: The trusted computing base (TCB) of a computer system is the set of all hardware, firmware, and/or software components that are critical to its security, [ in the sense that bugs or vulnerabilities occurring inside the TCB might jeopardize the security properties of the entire system. By contrast, parts of a computer system outside the TCB must not be able to misbehave in a way that would leak any more privileges than are granted to them in accordance to the security policy. source: wikipedia ]
