The Windows DNS Server audit records must be backed up at least every seven days onto a different system or system component than the system or component being audited.

Description

<VulnDiscussion>Protection of log data includes ensuring log data is not accidentally lost or deleted. Backing up audit records to a different system or onto media separate from the system being audited on a defined frequency helps to ensure the audit records will be retained in the event of a catastrophic system failure. 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 applies only to applications that have a native backup capability for audit records. Operating system backup requirements cover applications that do not provide native backup functions.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
