(in versions v2 r1 through v1 r1)
Title
RHEL 8 user account passwords must be configured so that existing passwords are restricted to a 60-day maximum lifetime. (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
Check whether the maximum time period for existing passwords is restricted to 60 days with the following commands: $ sudo awk -F: '$5 > 60 {print $1 " " $5}' /etc/shadow $ sudo awk -F: '$5 <= 0 {print $1 " " $5}' /etc/shadow If any results are returned that are not associated with a system account, this is a finding.
Fix Text
Configure non-compliant accounts to enforce a 60-day maximum password lifetime restriction. $ sudo chage -M 60 [user]
