Description
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. Sending DNS transaction data to the null channel would cause a loss of important data.
