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. Some information about some common security problems found on Cisco Routers, can be read on the text “Exploiting Cisco Routers”, available at: http://www.securityfocus.com/infocus/1734

In this article I will give you 8 steps, easy to follow, to minimize your Cisco router exposure by turning off some unused services, applying some access control and applying some security options available on that.
