TOSS 5 must log username information when unsuccessful login attempts occur.

Without auditing these events, it may be harder or impossible to identify what an attacker did after an attack.

Verify the "/etc/security/faillock.conf" file is configured to log username information when unsuccessful login attempts occur using the following command:

$ grep audit /etc/security/faillock.conf

audit

If the "audit" option is not set, is missing, or is commented out, this is a finding.

Configure TOSS 5 to log username information when unsuccessful login attempts occur.

Add or modify the "/etc/security/faillock.conf" file to match the following line:

audit
