Discussion

Users must be aware of activity that occurs regarding their account. Providing users with information regarding the number of unsuccessful attempts that were made to login to their account allows the user to determine if any unauthorized activity has occurred and gives them an opportunity to notify administrators.

Check Content

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.

Fix Text

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
