Tips For Security In Cisco Routers

Getting the most out of router security is important for securing one’s network. It helps keep a networking running smoothly and without problem. Computer network technicians will do good to remember two commands in particular: enable secret and enable password.

The outdated version of the password protection routines is the enable password command.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.

Gaining access to a Cisco router’s running configuration is easy. Use the running configuration command to bring up the currently stored settings of the router. If both enable password and enable secret were used, administrators can see that enable password is readable for all to see! The enable secret password that comes after it is unreadable, as it is stored as an MD5 encrypted text.

The enable secret command is the better password handling command, although enable password is still able to be used. Cisco router operating systems before version 10.3, the enable password is the only command that is able to be used. In such a case, it’s important for computer network technicians to upgrade to the latest IOS version for better security.

Final Thoughts

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.
