This read-only object returns an integer counter representing the cumulative number of failed login attempts by the cryptographic officer since the last successful authentication. Security monitoring systems use this counter to detect brute-force attacks, password guessing attempts, and unauthorized access attempts against the encryption module. A concrete example would be a counter value such as 0, 1, 5, 10, or higher, with some systems auto-locking the module if this exceeds a threshold like 3 or 5 attempts.
