SV-99115r1_rule SLES for vRealize must enforce 24 hours/1 day as the minimum password lifetime.

Vulnerability 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

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
