Fix Recommendation

Configure TOSS 5 to provide users with feedback on when account accesses last occurred by setting the required configuration options in "/etc/pam.d/postlogin".

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

session required pam_lastlog.so showfailed

Check Contents

Verify users are provided with feedback on when account accesses last occurred using the following command:

$ sudo grep pam_lastlog /etc/pam.d/postlogin

session required pam_lastlog.so showfailed

If "pam_lastlog" is missing from "/etc/pam.d/postlogin" file, or the silent option is present, this is a finding.
