Fail Close Definition: Fail close is a system configuration where access is denied by default if the security mechanisms fail or are unavailable, preventing unauthorized access to the system.
Fail Close is a security principle where a system automatically blocks access or denies entry when a failure or breach is detected. This approach ensures that in the event of a security incident, the default action is to restrict access rather than allow potentially unauthorized access. It helps to minimize the impact of security vulnerabilities by keeping systems in a secure state when errors or breaches occur.
