The main goal of DNSSEC is to protect against [[Data Spoofing|data spoofing]] and corruption. Initially, it was called only [[DNS]] (Domain Name System) and did not include security extensions. The main DNSSEC extensions are specified by RFC4033, RFC4034, and RFC4035. There are also some additional [[RFC]]s which provide supporting information. <ref>[http://www.dnssec.net DNSSEC Official Website/]</ref>
