To answer this question, we need to understand the purpose and implications of account lockouts.
Option A) Only be used on administrator accounts to ensure continuous access to users - This option is incorrect because account lockouts should be applied to all accounts, not just administrator accounts. Account lockouts are a security measure that helps protect user accounts from unauthorized access attempts, regardless of the type of account.
Option B) Only be used on user accounts to ensure that administrators are not locked out of the application - This option is incorrect because account lockouts are not solely focused on preventing administrators from being locked out. Account lockouts are implemented to protect user accounts from brute-force attacks and unauthorized access attempts, regardless of the user's role.
Option C) Only be used when there is a secure process to unlock the account - This option is correct. Account lockouts should only be used when there is a secure process in place to unlock the account. This ensures that if an account is locked due to multiple failed login attempts, the account owner can safely regain access through a secure and authenticated process.
Option D) None of the above - This option is incorrect because option C is the correct answer. Account lockouts should only be used when there is a secure process to unlock the account.
Therefore, the correct answer is C) Only be used when there is a secure process to unlock the account. This option is correct because it emphasizes the importance of having a secure process in place to unlock an account that has been locked due to multiple failed login attempts.
