Verify Permissions on /etc/audit/auditd.conf

An XCCDF Rule

Description

To properly set the permissions of /etc/audit/auditd.conf, run the command:

$ sudo chmod 0640 /etc/audit/auditd.conf

Rationale

Without the capability to restrict the roles and individuals that can select which events are audited, unauthorized personnel may be able to prevent the auditing of critical events. Misconfigured audits may degrade the system's performance by overwhelming the audit log. Misconfigured audits may also make it more difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.
