P-Cube Takes On Spam


P-Cube Inc. is introducing a spam-control software module for its “Engage 2.1” service-control platform that will allow broadband-service providers to control spam on their e-mail networks and prevent their customers from becoming unwitting accomplices.

So-called zombie spam -- which can take over a home computer without its owner knowing it -- results in millions of spam e-mail messages sent each day.

The spam control is a service module built into the P-Cube “SE 1000” and “SE 2000” service-control platforms, which can handle 40,000 and 100,000 broadband subscribers, respectively.

The software monitors all the activity emanating from a home PC. “We can map e-mails to each subscriber,” Gadekar said.

Any PC that transmits, say 1,000 e-mails in one hour -- or 5 megabytes of e-mail over a 24 hour period -- can be targeted.

Once identified, P-Cube (which Cisco Systems Inc. agreed to acquire last month) notifies the broadband-service provider so that it can determine what to do.

P-Cube’s technology can block only those e-mail messages headed to third-party servers. It can’t block e-mail sent within a broadband-service provider’s system.

Engage 2.1 can also send a message to an offending PC to inform the user that an e-mail virus has taken over their computer and provide information on how to cleanse the system.

P-Cube has tested the system with a digital-subscriber-line provider in Europe, which found 75 subscribers who had sent more than 1,000 e-mail messages in one hour, including 11 homes where more than 10,000 messages had been sent out.

Gadekar said P-Cube has rolled out the software to one Japanese MSO. A North American DSL deployment is scheduled over the next few months.
