A. Intruder detection lockout is a practical and effective defense mechanism against brute force attacks because it limits an attacker's ability to repeatedly guess passwords, making it significantly harder for them to compromise an account through trial and error.

Selected Answer: A
A brute force attack is a method of guessing a password or other authentication method by trying every possible combination of characters. To defend against this type of attack, an Intruder detection lockout is used. This mechanism automatically locks out an account after a certain number of failed login attempts, thus preventing the attacker from guessing the correct password. This technique helps to protect the system from unauthorized access, and also allows the organization to detect and respond to attempted breaches.
