DNS systems around the world are to become intelligent with the ability to spot malicious links.
Nominum has introduced the Intelligent DNS system with more than 100 million broadband households around the world benefiting from the service.
It claimed that older DNS systems are not designed to ensure user trust, honour end-user intent, support compliance efforts and provide navigation assistance. It can also often blindly direct users to internet destinations hosting unwanted, illegal or malicious content.
The Intelligent DNS systems play a critical role in ensuring that internet users benefit from an efficient, safe and secure internet experience.
Gopala Tumuluri, vice president of marketing and business development at Nominum, claimed that the DNS is the most critical junction in the network and an intelligent DNS is no longer just about tracking names to IP addresses, it is about improving service.
Tumuluri said: “Threats have grown in scope, size and efficiency to ensure that security measures have to keep a record on a network. More is needed to counter the threat.
“The old DNS doesn't care where the user was going, not a sufficient function of the DNS. So we're offering an intelligent DNS where there is policy support and it determines how data should be managed. The internet is an unsafe destination; the intelligent DNS will direct the user to a safe destination.”
When a user uses the Intelligent DNS and tries to access a malicious page, they will see a ‘teaching page' that instructs them on the danger of the content on the page they are trying to access. Tumuluri claimed that this will add value, as most users do not know better.
He also explained that it determines suspicious sites from external sources and from the address of the page.
Dr. Paul Mockapetris, chief scientist at Nominum, said: “Over the last 25 years the DNS has grown with the internet. The DNS was originally the scalable directory for host names and has expanded to include multiple independent databases for threat and reputation data.
"Intelligent DNS is the logical evolution of DNS to support all of these uses in a coherent framework. It lets ISPs create policies combining raw DNS directory data with other public and private information in real-time so users go to intended and safe destinations. ISPs can customise Intelligent DNS to meet the protection and compliance needs of individual users and jurisdictions.”
Nominum has also announced the end-of-life of its Caching Name Server (CNS). Launched eight years ago, it was designed to offer performance and availability improvements over other systems and became a cornerstone of network architectures, readily accommodating the rapid growth of broadband in that era. In light of these changes, Nominum no longer considers CNS or any other passive DNS system, a viable option for today's internet and its users.
Tom Tovar, CEO of Nominum, said: “CNS has been the workhorse of the broadband internet. It was also a highly successful product and a major contributor to Nominum's success.”
