Vulnerability 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
Verify users are provided with feedback on when account accesses last occurred by using the following command:
$ grep pam_lastlog /etc/pam.d/login
session required pam_lastlog.so showfailed

Fix
Configure Ubuntu 22.04 LTS to provide users with feedback on when account accesses last occurred.
Add or modify the following line at the top in the "/etc/pam.d/login" file:
session required pam_lastlog.so showfailed
