Worms have 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 collective probing and continuously replicating behavior exhibited by these attacks. Worms cause routers and flow-based devices to exhaust resources on processing excessive, malformed, maliciously crafted traffic. This degrades service levels for the entire network.
Individual protection, while ideal at the subscriber level, is not effective enough at the service provider level. A very small percentage of unprotected or poorly protected subscriber machines can create havoc for the rest of the service provider's network.
Sandvine's network-based worm mitigation solution attacks worms at all five stages of their development effectively closing down 98% of worm/DoS related traffic.
