Description

Any password, no matter how complex, can eventually be cracked. Therefore, passwords need to be changed periodically. If OL 8 does not limit the lifetime of passwords and force users to change their passwords, there is the risk that OL 8 passwords could be compromised.

Check Text (C-52131r779655_chk)

Verify 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.

Configure non-compliant accounts to enforce a 60-day maximum password lifetime restriction.

$ sudo chage -M 60 [user]
