SBC launches intrusion prevention service

PremierServ addition to managed security service promises to catch known and unknown network threats.

SBC Communications has added an intrusion prevention tool to its lineup of security services for corporate networks. The PremierServ Managed Intrusion Prevention Service, introduced Tuesday, uses a behavior-based approach to detect known worms and viruses, the company said. It also promises to catch "zero day" intrusions, which take advantage of previously unknown vulnerabilities, on servers, desktops and other computers connected to the network.

The service uses a device provided by Mirage Networks that is installed on top of the network, SBC said. No additional desktop software is required, it added.
