Vulnerability Discussion

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

Check

Verify the SUSE operating system 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, the "silent" option is present, or the returned line is commented out, this is a finding.

Fix

Configure the SUSE operating system to provide users with feedback on when account accesses last occurred by setting the required configuration options in "/etc/pam.d/login".

Add the following line to the top of "/etc/pam.d/login":

session required pam_lastlog.so showfailed
