Title
RHEL 8 user account passwords must have a 60-day maximum password lifetime restriction. (Cat II impact)
Discussion
Any password, no matter how complex, can eventually be cracked. Therefore, passwords need to be changed periodically. If RHEL 8 does not limit the lifetime of passwords and force users to change their passwords, there is the risk that RHEL 8 passwords could be compromised.
Check Content
Verify that RHEL 8 enforces a 60-day maximum password lifetime for new user accounts by running the following command: $ sudo grep -i pass_max_days /etc/login.defs PASS_MAX_DAYS 60 If the "PASS_MAX_DAYS" parameter value is greater than "60", or commented out, this is a finding.
Fix Text
Configure RHEL 8 to enforce a 60-day maximum password lifetime. Add, or modify the following line in the "/etc/login.defs" file: PASS_MAX_DAYS 60
