AlmaLinux OS 9 must configure the use of the pam_faillock.so module in the /etc/pam.d/password-auth file.
An XCCDF Rule
Description
By limiting the number of failed logon attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute-force attacks, is reduced. Limits are imposed by locking the account. If the pam_faillock.so module is not loaded, the system will not correctly lockout accounts to prevent password guessing attacks.
