Dealing with worms that travel over their networks could cost North American ISPs as much as $245m (£134m) in 2004, according to a study released on Wednesday by peer-to-peer management company Sandvine. For service providers worldwide, the overall expense could reach $370m. The totals include the cost of tactical-response teams, swamped customer support resources, higher transit costs, and probable customer churn due to a loss of positive brand image over time.
Sandvine estimated that, on any given day, between 2 percent and 12 percent of traffic on service provider networks is malicious. Even on networks with good security, malicious traffic accounts for 5 percent of all data.
In addition to dealing with event-related attacks triggered by worms like Slammer, Sobig and the recent MyDoom, ISPs have to contend with daily denial-of-service attacks and persistent low-level incursions from remnants of earlier worms still active on the PCs of residential subscribers.
All told, worms have become an operational preoccupation for network managers, in addition to being a drag on profits, Sandvine said.
"Worms exact a massive toll by forcing service providers to mobilise premium resources in order to quell attacks and protect the subscriber experience," Tom Donnelly, vice president of marketing and sales at Sandvine, said in a statement. "Uncovering the true costs and inefficiencies that worms impose on the broadband sector is crucial if we're going to identify appropriate solutions."

What a load of CRAP! Your trying to tell me the $44.95 I pay a month for broadband is not almost complete profit for the ISP. I've contracted for ISPs in the past, and their biggest headache was having effective order tracking and implementation systems, not the network itself. My ISP simply blocked all email traffic from the worms mentioned. Problem solved!
