Options In Enforcing 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.
There are a total of five different commands that can be used in regards to the different passwords that can be secured. The first to review is the command "Enable password." This command is an outdated form, although it is still in use among older routers and with those who haven't upgraded their IOS. Enable password in particular is flawed because it uses no encryption to store the password in question.
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.
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.

Network security is a big industry. Regardless of the thousands of dollars businesses use to propel their business, the smallest of commands such as enable secret and enable password will do a world of good for the network as a whole. Be sure to read more on the subject in Cisco documentation and online networking resources to get the full effect on how to use, maintain, and prepare Cisco routers for security topics.
