Title

The operating system must back up audit records at least every seven days onto a different system or system component than the system or component being audited. (Cat II impact)

Discussion

Protection of log data includes assuring log data is not accidentally lost or deleted. Backing up audit records to a different system or onto separate media than the system being audited on an organizationally defined frequency helps to assure in the event of a catastrophic system failure, the audit records will be retained. This helps to ensure a compromise of the information system being audited does not also result in a compromise of the audit records. This requirement can be met by the operating system continuously sending records to a centralized logging server.
