Trusted Computing Base

The Trusted Computing Base (TCB) refers to the essential components of a computer system that must work correctly to ensure the system's security. This includes hardware, software, and firmware that enforce security policies and protect sensitive data. Essentially, the TCB acts as a secure foundation that helps prevent unauthorized access and attacks. If the TCB is compromised, the entire system may be at risk. By focusing on strengthening the TCB, organizations can better safeguard their information and maintain trust in their computing environments.
