8 steps to protect your Cisco router

Contributed by Daniel B. Cid and restored from the old Infosecwriters archive.

Network security is a completely changing area; new devices like IDS (Intrusion Detection systems), IPS (Intrusion Prevention systems), and Honeypots are modifying the way people think about security. Companies are spending thousand of dollars on new security devices, but forgetting the basic, the first line of defense: the border router.

Although a lot of people may think that routers don’t need to be protect, they are completely wrong. A lot of secure problems appear all time against this kind of device and most of them are vulnerable.
