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, then the password could be repeatedly changed in a short period of time to defeat the organization's policy regarding password reuse.

Check Content

To check that SLES for vRealize enforces 24 hours/1 day as the minimum password age, run the following command:

# grep PASS_MIN_DAYS /etc/login.defs | grep -v '#'

The DoD requirement is "1".

If "PASS_MIN_DAYS" is not set to the required value, this is a finding.

Fix Text

To configure SLES for vRealize to enforce 24 hours/1 day as the minimum password age, edit the file "/etc/login.defs" with the following command:

# sed -i "/^[^#]*PASS_MIN_DAYS/ c\PASS_MIN_DAYS 1" /etc/login.defs
