Fix Recommendation

Configure TOSS 5 to maintain the contents of the faillock directory after a reboot.

Add or modify the "/etc/security/faillock.conf" file to match the following line:

dir = /var/log/faillock

Check Contents

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.
