Secure your network with BT Diamond IP DNS security solutions

The domain name system (DNS) is fundamental to the proper operation of nearly every IP network application, from web browsing, email, to multi-media applications and more. DNS provides the lookup and translation services from name to IP addresses that are used by computers to communicate. An attack that renders the DNS service unavailable or which manipulates the integrity of the data contained within DNS can effectively bring a network down.

DNS has proven extremely effective and scalable in practice and most people take DNS for granted given this and its proven reliability. However, its essential function and decentralised architecture serve to attract attackers seeking to exploit the architecture and its rich data store for sinister activities. BT Diamond IP offers a defense in depth approach to reduce exposure and mitigate impacts including DNS security extensions (DNSSEC), denial of service mitigation, access control lists, DNS firewall, inbound and outbound rate limiting and more.
