The company has released Network VirusWall, an appliance that can block worm traffic and quarantine infected network segments, a new version of Control Manager, and a vulnerability assessment service for Microsoft networks.
The need is driven by worms such as Blaster and Code Red, which spread around the internet by automatically exploiting vulnerabilities in prolific software. This allowed them to spread and cause more damage than typical e-mail-borne worms.
Rather than scan files for malware, which is the way most anti-virus gateways behave, VirusWall scans traffic as it passes through for signatures of known worms, according to senior director of Americas marketing Dan Glessner
VirusWall can also block unknown worms based on heuristics that look for wormlike behavior and traffic that resembles exploits for known vulnerabilities, said global marketing manager Raj Venkat.
The device can also prevent unknown or new machines, such as contractors’ laptops for example, from connecting to the network if security policies, such as the need to have a current set of virus definitions installed, are not met.
Venkat said the system can do this without the need for any agent software to be installed, by testing the anti-virus software for its update level. Third-party anti-virus software is supported.
The first product in this new line of appliances is the medium-range Network VirusWall 1200, which sells for $5,995. Trend’s Glessner said the company has plans for faster, higher-end models suitable for different points in the network.
Trend also yesterday launched Control Manager 3.0, which the company said improves on the reporting features from 2.5, and also allows a new Vulnerability Assessment service, which scans the network for Microsoft software vulnerabilities.
