There are many websites and tutorials available to learn more about the importance of DNSSEC. We have captured some of that information here to provide you with a starting point to your DNSSEC Education.

DNSSEC is a set of DNS extensions which provide 3 basic functions:

  • Data Origin Authentication - assures that data is received from the authorized DNS server; can protect from impersonation attacks
  • Data Integrity - assures that data received matches data on the origin DNS server, and is not modified during transit; protects from man-in-the-middle type pollution attacks.
  • Authenticated Denial of Existence - assures that a "Non-existent" response is valid.

DNSSEC Technical Information and Documentation

The following "Request for Comments" (RFCs) defines the technical core of DNSSEC specifications.
