Discussion

Enforcing a minimum password lifetime helps to prevent repeated password changes to defeat the password reuse or history enforcement requirement. If users are allowed to immediately and continually change their password, the password could be repeatedly changed in a short period of time to defeat the organization's policy for password reuse.

Check Content

Verify the minimum time period between password changes for each user account is one day or greater with the following command:

$ sudo awk -F: '$4 < 1 {printf "%s %d\n", $1, $4}' /etc/shadow

If any results are returned that are not associated with a system account, this is a finding.

Fix Text

Configure RHEL 10 so that noncompliant accounts enforce a 24 hours/1 day minimum password lifetime:

$ sudo passwd -n 1 [user]
