Lockouts persisting across reboots ensure that the account is only unlocked by an administrator. If the lockouts did not persist across reboots, an attacker could simply reboot the system to continue brute-force attacks against the accounts on the system.

Check Content

Verify the "/etc/security/faillock.conf" file is configured use a nondefault faillock directory to ensure contents persist after reboot using the following command:

$ grep 'dir =' /etc/security/faillock.conf

dir = /var/log/faillock

If the "dir" option is not set to a nondefault documented tally log directory, is missing or commented out, this is a finding.
