Information
Monitor login and logout events. The parameters below track changes to files associated with login/logout events. The file /var/log/faillog tracks failed events from login. The file /var/log/lastlog maintain records of the last time a user successfully logged in.
Rationale:
Monitoring login/logout events could provide a system administrator with information associated with brute force attacks against user logins.
Solution
Edit or create a file in the /etc/audit/rules.d/ directory ending in .rules Example: vi /etc/audit/rules.d/audit.rules and add the following lines:
-w /var/log/faillog -p wa -k logins -w /var/log/lastlog -p wa -k logins
Notes:
Reloading the auditd config to set active settings may require a system reboot.
