SV-50280r1_rule Users must be warned 7 days in advance of password expiration.

Vulnerability discussion

Setting the password warning age enables users to make the change at a practical time.

Check content

To check the password warning age, run the command: $ grep PASS_WARN_AGE /etc/login.defs The DoD requirement is 7. If it is not set to the required value, this is a finding.

Fix text

To specify how many days prior to password expiration that a warning will be issued to users, edit the file "/etc/login.defs" and add or correct the following line, replacing [DAYS] appropriately: PASS_WARN_AGE [DAYS] The DoD requirement is 7.

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.
