True or False: A system that implements the 'fail securely' principle should default to granting access when authentication mechanisms fail.
False
True
The correct answer is False. The 'fail securely' principle states that when a system fails, it should default to a secure state rather than an insecure one. In practice, this means that when authentication mechanisms fail or encounter errors, the system should deny access rather than grant it. This ensures that security is maintained even during failure conditions.
Failing securely is sometimes referred to as 'fail-safe' or 'fail-closed' and is an important security design principle that helps prevent unauthorized access during exceptional conditions or system failures. If a system were to grant access by default when authentication fails, it would create significant security vulnerabilities that could be exploited by attackers.
