Worm activity, often the prelude to both spam and denial of service (DoS) attacks, has shifted focus to residential broadband subscribers -- the weakest, most uncontrolled point in the Internet. Home users are difficult to protect en masse, and service providers are forced to bear escalating support costs and attacks on their ability to deliver the best possible Internet experience.
Service providers face a different dimension of the worm/virus problem by the continuously replicating behavior exhibited by worms and DoS attacks. DoS attacks, specifically, degrade service levels by denying subscribers access to Internet resources, often resulting in complex helpdesk calls.
Sandvine's Network-Based DoS Mitigation preserves the subscriber experience by filtering DoS attacks and eliminating malicious traffic while allowing all legitimate requests to proceed through the network.
