Description
Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. The actual auditing is performed by the operating system/network device manager, but the configuration to trigger the auditing is controlled by the DNS server. Because the configuration of the audit logs on the DNS server dictates which events are logged to correlate events, the permissions for configuring the audit logs must be restricted to only those with the role of information system security manager (ISSM) or those appointed by the ISSM.
