Vulnerability discussion

The major threat associated with DNS forged responses or failures are the integrity of the DNS data returned in the response. The principle of DNSSEC is to mitigate this threat by providing data origin authentication, establishing trust in the source. By requiring remote clients to obtain origin authentication and integrity verification assurances for the host/service name to network address resolution information obtained through the service, data origin is validated. Ensuring all name servers have static IP addresses makes it possible to configure restricted DNS communication, such as with DNSSEC, between the name servers.

Check content

Log on to the DNS server using the Domain Admin or Enterprise Admin account. Locate the “Network Internet Access” icon, right-click on it and select "Open Network & Sharing Center". Click on "Change adapter settings". Right-click on the Ethernet and click “Properties”. Select Internet Protocol Version 4 (TCP/IPv4) and click “Properties”. Verify the “Use the following IP address” is selected, with an IP address, subnet mask, and default gateway assigned. If the “Use the following IP address” is not selected with a configured IP address, subnet mask, and default gateway, this is a finding.

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.
