The DNS is a naming system for resources connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most importantly, it translates domain names in a meaningful way to humans from the numerical identifiers associated with networking.
DNS is the backbone of all Internet transactions, without it there is no Internet. So it should be no surprise that the DNS is a critical network service. DNS directly impacts the speed, reliability and security of broadband Internet access for your subscribers. A slow DNS server will lead to a poor end-user experience and, worse, a DNS failure will cause the Internet to go “down” for all users.
The way that Intelligent DNS systems work is very simple and takes advantage of the fact that virtually every Internet Protocol (IP) application relies on the DNS to function. Intelligent DNS performs all of the normal functions of regular DNS systems today. What separates an intelligent DNS system is the ability to simply look at DNS requests coming from hosts on a network, and make decisions based upon the enterprise security policy before responding to the original request.
Intelligent DNS will play an important role in making the Internet better, safer and faster. Intelligent DNS systems have additional features, and incorporate additional information, to secure the DNS itself, to protect networks from bots, and to protect end users from a wide variety of Internet threats:
Layered security defenses that far exceed capabilities of conventional DNS servers in deterring attackers.
Built in resilience to DDoS attacks and unusual traffic spikes.
Secure integration with real time data feeds to enable up to the minute enforcement of policies for safeguarding Internet interactions and improving the browsing experience.
Embedded facilities for gathering, aggregating and forwarding detailed DNS data to external systems for detecting emerging threats and visualizing network traffic patterns.
An intelligent DNS system introduces a completely new approach for detecting and deterring security threats that does not rely on any form of packet inspection. Rather than filtering and inspecting packets randomly transiting through a network, intelligent DNS systems operate in a completely different part of the normal IP communications flow.
