Vulnerability discussion

Any password, no matter how complex, can eventually be cracked. Therefore, passwords need to be changed periodically. If the SUSE operating system does not limit the lifetime of passwords and force users to change their passwords, there is the risk that the SUSE operating system passwords could be compromised.

Check content

Verify that the SUSE operating system is configured to create or update passwords with a maximum password age of "60" days or less. Check that the SUSE operating system enforces "60" days or less as the maximum password age with the following command: # grep PASS_MAX_DAYS /etc/login.defs The DoD requirement is "60" days or less (greater than zero, as zero days will lock the account immediately). If PASS_MAX_DAYS is not set to "60" days or less, this is a finding.

Fix text

Configure the SUSE operating system to enforce a maximum password age of "60" days or less. Edit the file "/etc/login.defs" and add or correct the following line. Replace [DAYS] with the appropriate amount of days: PASS_MAX_DAYS [DAYS] The DoD requirement is "60" days or less (greater than zero, as zero days will lock the account immediately).

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.
