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 " " 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.
