Description
Without generating audit records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit records can be generated from various components within the information system (e.g., module or policy filter).

Events cannot be modified. Log on to the VM console and run the following command: chkconfig auditd If the Audit Service is not in a running state, this is a finding. Verify the operating system generates audit records when successful/unsuccessful attempts to access privileges occur. If it does not, this is a finding.
