The Cisco IOS is powerful and already running on your routers. You would think that it could play a part in this virus detection and prevention, right? In my latest TechRepublic article, learn how Cisco Automatic Signature Extraction can help to prevent zero-day virus attacks. This is a new feature that works with a Linux server as a collector of the signatures. That “collector” communicates back to the routers to block the malicious traffic. Currently, the collector is in limited release and you have to contact your Cisco rep to obtain it. Still, I think this feature has a lot of promise for the future.
