The RealSecure Network Sensor 7.0, the newest in its line of network security products, has the ability to detect hybrid threats such as the Code Red and Nimda worms, before signatures have become available for them.
ISS added that signatures for the open source intrusion detection system Snort are supported. Signatures can also be updated automatically in the new version.
Alerts can be sent via pager and inserted into trouble ticket. The product will be released in the second quarter at a starting cost of $8,995 (£6,310).
RealSecure Guard, an in-line intrusion detection device that blocks or analyses traffic as it flows through a network. If the traffic is malicious, it is blocked using firewall rules.
The device is available immediately at a cost of $11,000 (£7,715).
ISS also announced a new architecture for its sensors that will bring users more modular security options. The architecture takes a page from the server market by mirroring the "server blade" system used there to add features and functions through removable, plug-and-play hardware boards. In ISS's case, it will mean that the company's sensors can be updated faster with new functionality via users downloading small software libraries that contain the latest features.
ISS added that its RealSecure SiteProtector management console will expand the number of security systems that it can draw data from to include those offered by Check Point Software Technologies, Cisco Systems, Nokia and Sun.
