This audit has been deprecated and will be removed in a future update.

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. The file /var/log/tallylog maintains records of failures via the pam_tally2 module

Note: Reloading the auditd config to set active settings requires the auditd service to be restarted, and may require a system reboot.

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/50-logins.rules
Add the following lines:

-w /var/log/faillog -p wa -k logins
-w /var/log/lastlog -p wa -k logins
-w /var/log/tallylog -p wa -k logins
