The identification of the computers in Internet is carried out through the directions IP, which are unique for each equipment. Then, system DNS, in Spanish System of Name of Domain, is the one that is in charge to establish the relation between the names of domain and directions IP.

Starting off of this base, the DNSSEC is a set of extensions of security developed for the service of DNS that makes use of an asymmetric coding to provide the maximum security. Its main objective is to verify which is the origin of a servant DNS, as well as to guard by the security of the data between servers DNS.

How DNSSEC works

Protocol DNSSEC is an extension of the protocol DNS that provides security to him. One of its main functions is to avoid attacks as the denominated poisoning of cache, which is more and more habitual in the virtual world; it consists of sending answers false with the only objective to direct to the users to a destiny different from the real domain.

The operation of DNSSEC is the following one. When a user accedes to a site with qualified DNSSEC is the following one. First of all, the navigating Web verifies servers DNS related to the domain. Secondly, it verifies that public the digital companies that receive with the companies published in the Registry.

If they agree, the navigating Web confirms the request and, this way, it shows the content the user. In case the companies do not agree, the user cannot see the content of the website.
