Enabling account lockout following a certain number of invalid attempts is an effective method for protecting servers from password cracking attempts. This security measure involves temporarily locking an account after a predefined number of consecutive failed login attempts. This approach significantly reduces the risk of automated attacks, such as brute force attacks, where an attacker systematically tries different password combinations to gain unauthorized access.

By limiting the number of attempts, administrators can effectively slow down these attacks, as the account will become inaccessible after a few incorrect tries. This forces attackers to rethink their approach, as the time and resources needed to bypass the lockout become prohibitive. Furthermore, this tactic can be combined with alerts to notify administrators of potential unauthorized access attempts, enhancing overall security.

It is important to balance the lockout duration and the maximum number of attempts to avoid inconveniencing legitimate users while still providing robust protection against malicious activities. In contrast to this practice, disabling account lockout, allowing unlimited password attempts, and simply asking users to remember their passwords do not provide adequate defenses against password cracking attempts, as they may leave accounts susceptible to exploitation without any barriers to automated attack methods.
