Options In Enforcing Security In Cisco Routers

By: Zachary Schuessler

A network administrator has a tough job to complete. After all, they are responsible for the very security of the network they are supposedly administrating. This is a very tough job, with so many threats and vulnerabilities out to date. This is especially true with router configuration, where threats need to be neutralized.

There are several commands in which are used to secure a router in terms of passwords. Cisco announced that one in particular, "Enable password," has become outdated and vulnerable to security risk. This is because the command uses no encryption to store passwords, and this can lead to hackers finding passwords out and retrieving them with ease.

A computer network is best secured on the router side of things with encryption. Cisco realized this, and released the "Enable Secret" command in an IOS update. Enable secret allows network administrators to get their network using encryption and running great without fear of hackers finding the password out and causing a world of hurt on the computer network in question.

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.

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.

Closing Comments

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.
