DNS Attacks on the Rise
NEW YORK -- Mobile Network Security Strategies -- Attacks against the domain name system (DNS) have risen in the past year, and they have grown more sophisticated and targeted in the process.
Dr. Srinivas Mantripragada, vice president of technology at the network security vendor Infoblox Inc. , said the attacks are taking on two forms: outside-in to disrupt the DNS service, as in a denial of service (DOS) attack; and inside-out, using the DNS as a vector to exploit for spam, botnets, or phishing. (See: Infoblox Intros DNS Appliance.)
Seeing that virtually every service that network operators provision has a DNS component to it, it's easy to see why they are concerned, too. "DNS is the No. 2 attack vector, right next to HTTP," Mantripragada said. "It's growing 200% year over year. It's an important pillar that needs to be fortified more."
