Vulnerability discussion

DNS software administrators require DNS transaction logs for a wide variety of reasons including troubleshooting, intrusion detection, and forensics. Ensuring that the DNS transaction logs are recorded on the local system will provide the capability needed to support these actions.

Check content

Verify that the BIND 9.x server is configured to send audit logs to a local log file. Inspect the "named.conf" file for the following: logging { channel local_file_channel { file "path_name" versions 3; print-time yes; print-severity yes; print-category yes; }; category category_name { local_file_channel; }; If a logging channel is not defined for a local file, this is a finding. If a category is not defined to send messages to the local file channel, this is a finding.

Fix text

Edit the "named.conf" file and add the following: logging { channel local_file_channel { file "path_name" versions 3; print-time yes; print-severity yes; print-category yes; }; category category_name { local_file_channel; }; }; Restart the BIND 9.x process.

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.
