Discussion

Configuration settings are the set of parameters that can be changed in hardware, software, or firmware components of the system that affect the security posture and/or functionality of the system. Security-related parameters are those parameters impacting the security state of the system, including the parameters required to satisfy other security control requirements. Security-related parameters include, for example: registry settings; account, file, directory permission settings; and settings for functions, ports, protocols, services, and remote connections.

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, is not "required", 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/login".  
 
Add the following line to the top of "/etc/pam.d/login": 
 
session     required      pam_lastlog.so showfailed
