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.
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
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.
