HP Virus Throttle puts brake on worms

Hewlett-Packard has introduced software designed to limit the spread of viruses across corporate networks and reduce the damage they cause.

HP Virus Throttle can help businesses detect, contain and slow the rate at which an attack spreads inside the core of the IT infrastructure, the company said. Originally developed by HP Labs, Virus Throttle is available for HP Proliant servers and Procurve Networking by HP 5300 switches.

Unlike traditional virus scanning products, which rely on virus signatures, Virus Throttle detects abnormal, virus-like behaviour and slows down the number of different connections an infected machine can make until an administrator can determine whether the problem is viral in nature and take further action.

The rapid rate at which worms and viruses spread across networks makes it difficult for IT administrators to react quickly to limit the damage that an attack may cause to corporate systems.

HP said Virus Throttle monitors network connection requests and detects abnormal activity of the type typically exhibited by a virus attempting to propagate within a network. According to HP, the software is able to react in milliseconds, without waiting for an operator's attention.

Tony Redmond, vice-president and chief technology officer, HP Security Office and HP Service, said, "If IT systems were 'intelligent' enough to automatically detect and shut down attacks before they spread, administrators would spend less time and money trying to catch up."

The software is part of HP's wider security strategy. HP Labs, the company's central research facility, is also working on damage-containment software that would prevent certain viruses from corrupting entire systems.
