Vulnerability 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 a 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 only applies to applications that have a native backup capability for audit records. Operating system backup requirements cover applications that do not provide native backup functions.

Check content

Review the DNS system configuration to determine if audit record content is sent to a centralized audit log repository, either directly by the DNS system or by the underlying O/S. If the DNS system is not configured to support centralized logging and auditing, this is a finding.

Fix text

Configure the DNS server or the underlying O/S to send audit log content to a centralized logging facility.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
