1.325 RHEL-09-611080

Information

RHEL 9 passwords must have a 24 hours minimum password lifetime restriction in /etc/shadow.

GROUP ID: V-258105
RULE ID: SV-258105r1045212

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 regarding password reuse.

Solution

Configure noncompliant accounts to enforce a 24 hour minimum password lifetime:

$ sudo passwd -n 1 [user]
