Containing Rogue Wireless Lans in your Corporate Environment

Raj Perumal Raj Perumal Profile: Raj Perumal

So one of the more common technologies I see being implemented in my day to day work is wireless. Wireless is one of those mixed bags. It’s a great technology that offers a lot of convenience to your users but at the same time it can be a huge security risk and a pain to maintain.

One of the more common problems you might seen in a corporate environment is users buying their own cheap wireless access point like a Linksys or D-LinkĀ from their local electronics retailer and plugging it into a network port in their office to give them wireless capabilities. This isn’t only bad for security, but it can also interfere with any wireless networks you already have setup.

Luckily Cisco has an answer to this problem. If you use the Cisco wireless controllers, they have a feature built-in to stop this. They refer to non-authorized wireless in your environment as “Rogue AP’s”. These rogue AP’s can be “contained” by use of the Cisco software. All you have to do is tell the wireless controller to contain any rogue AP’s it sees and from that point on it renders those AP’s useless in your corporate environment.
