Tips For Security In Cisco Routers
Cisco is the leader in routing and switching devices, but they aren’t without their problems. Routers need to be secured with several different configurations so as to best ensure a network is not vulnerable to outside attack. How to configure the Cisco router becomes the task, and with what commands is the problem.
The outdated version of the password protection routines is the enable password command. Enable password puts a password on the privileged mode of the Cisco router, although there are some large flaws with this command. First and foremost, the command is stored as clear text, which is a phrase that describes a password stored without encryption.
An updated version of the previous command is “Enable secret,” which Cisco released for using encryption on the passwords. The difference can be seen in the running configuration of the router, most notably where the password is now stored in random letters and numbers instead of showing the actual password. This is an important step in securing a router against prying eyes.
For anyone running an IOS version below 10.3, the enable secret command will not be available. Thus, it is extremely important that all Cisco router users update to the latest IOS if it hasn’t been done so already. By default, newer IOS versions will use enable secret over enable password- which is obviously the better choice in the matter.
Much of the benefit from the enable secret command comes from protecting the running configuration from prying eyes. And as far as computer networking security goes, even the smallest bit of help in security goes a long way in network stability. And when companies and businesses depend on network stability for a source of income, lacking it could run a business and its services into the ground.

Cisco routers aren’t a safety hazard by any means, but updating to the latest IOS version and taking advantage of newer commands such as “Enable secret” is the best bet in keeping the computer network up and running for months to come without hassle.
