SLES-12-010260 - The SUSE operating system must be configured to create or update passwords with a minimum lifetime of 24 hours (one day).

Information

Enforcing a minimum password lifetime helps 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 the SUSE operating system to enforce 24 hours/one day or greater as the minimum password age.

Edit the file '/etc/login.defs' and add or correct the following line. Replace [DAYS] with the appropriate amount of days:

PASS_MIN_DAYS [DAYS]

The DoD requirement is '1' but a greater value is acceptable.
