Fix Recommendation

Configure Amazon Linux 2023 to generate audit records for all account creations, modifications, disabling, and termination events that affect "/etc/passwd".

Enable the auditd daemon so that it can start at boot time:

$ sudo systemctl enable auditd

Add or update the following file system rule to "/etc/audit/rules.d/audit.rules":
-w /etc/passwd -p wa -k identity

Then, restart the auditd service for the changes to take effect:

$ sudo service auditd restart

Check Contents

Verify Amazon Linux 2023 generates audit records for all account creations, modifications, disabling, and termination events that affect "/etc/passwd" with the following command:

$ sudo auditctl -l | egrep '(/etc/passwd)'
-w /etc/passwd -p wa -k identity

If the command does not return a line, or the line is commented out, this is a finding.
