Certified Information Systems Security Professional (CISSP) Practice Exam

Trusted recovery significantly enhances system security by establishing a reliable process for restoring systems after a failure or a security incident. When a system undergoes a failure—whether due to hardware issues, software errors, or security breaches—it's crucial to have a robust method for recovering that system while maintaining its security posture.

This process involves verifying that the recovery procedures do not introduce vulnerabilities or compromise the integrity of the system. Trusted recovery ensures that backup systems are secure and that the restored data has not been tampered with. It also includes measures to validate the recovery state, ensuring that systems can return to a known good configuration without risking further exposure to threats.

While ensuring that only authorized users access sensitive systems is also critical for security, that aspect primarily deals with access control rather than recovery. Similarly, while simplifying user experience and aiming to eliminate potential security threats are important, they are not the core functions directly attributed to the concept of trusted recovery. The principal benefit remains the assurance provided through a systematic approach to restoring systems safely and securely.
