Vulnerability discussion

Providing users with feedback on when account accesses last occurred facilitates user recognition and reporting of unauthorized account use.

Check content

Verify users are provided with feedback on when account accesses last occurred. Check that "pam_lastlog" is used and not silent with the following command: # grep pam_lastlog /etc/pam.d/login session required pam_lastlog.so showfailed If "pam_lastlog" is missing from "/etc/pam.d/login" file, or the "silent" option is present, this is a finding.

Fix text

Configure the Ubuntu operating system to provide users with feedback on when account accesses last occurred by setting the required configuration options in "/etc/pam.d/postlogin-ac". Add the following line to the top of "/etc/pam.d/login": session required pam_lastlog.so showfailed

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.
