The internet's system for connecting users with online resources is key to combating cybercrime, says network naming firm Nominum.
The domain name service (DNS) is the perfect place to implement security as it touches every internet transaction, said Gopala Tumuluri, vice-president marketing at Nominum.

Legacy DNS systems are unable to block malicious internet content because they are designed to passively answer network queries.
But Nominum, whose chief scientist Paul Mockapetris invented the DNS, has developed software that addresses this weakness.
The firm's Intelligent DNS software has been designed to give internet service providers and businesses the ability to tap into real-time intelligence to block threats.
The system automatically combines standard DNS data with multiple real-time sources of information on phishing, botnets and malware to block connections to malicious sites.
Unlike traditional security software, Intelligent DNS can actively block attempted connections to botnets' command centres even after malware infection, said Tumuluri.
The system is also able to identify potential threats by monitoring all DNS activity and allows businesses to connect to third-party sources of threat information.
"DNS is a great source of threat information because every single device, application and user on the internet uses DNS," said Tumuluri.
Intelligent DNS, which replaces Nominum's caching name server (CNS), also enables businesses and ISPs to customise policies based on regulatory requirements.
