5 Configuration Changes to Fortify Your WLAN Security

You can protect your small business wireless network from intruders with a few simple tweaks

A wireless network makes sense for small businesses.  It enables you to connect wired and wireless devices, allowing you to expand your network operations and keep employees productive.  Also, a wireless LAN (WLAN) is easier and less expensive to set up than a wired network, and gives employees and guest users quick, convenient access to the Internet from anywhere in your office.

Deploying a wireless network is easy in part because the networking equipment, including wireless routers and wireless access points, ships with important configuration settings preconfigured. However, these preset passwords, along with other improperly set configurations, can lead to catastrophic breaches in network security. To ensure your wireless network is secure, the devices must be configured to block intruders and protect users.

Here are five changes you can make to your WLAN configuration settings to lock down your wireless network and provide business-class security:

It’s Not the Wireless! BYOD and Cisco Live! Customer Guest Blog

This week I’m happy to continue our customer guest-blog series with Blake Krone, CCNA Wireless, CCNP Wireless, and CCIE Wireless candidate. You can read more from Blake on his blog, Digital Lifestyle or connect with him via Twitter @blakekrone. Read on for a Cisco Live perspective from a true wireless professional.

Recently 14,000+ technology geeks invaded Las Vegas for Cisco Live! 2011 at Mandalay Bay Convention Center. For me this was my 4th year in a row attending Cisco Live! and the 2nd in a row at Vegas. If you have never attended a Cisco Live! event in person I strongly suggest that you try to budget for it next time around. Not only is this the best week to jump head first into all areas of Cisco’s product portfolio but it is also an opportunity to see how the products can come together to provide connectivity for devices and people.

For every Cisco Live! event that is held Cisco builds their own network to support the conference attendees, sponsors, and speakers. This gives Cisco the opportunity to get a large set of data points regarding their products performance in abusive conditions. Lately we have seen or heard about the BYOD (bring your own device) phenomenon that is sweeping across the enterprise network and there is no better place to see that than a large IT conference.

One can safely assume that for all the 14,000+ in attendance each person will have at least 1 Wi-Fi connected device. Now let’s assume that a large chunk of those in attendance are like me and also have their laptop and a tablet with them, that’s a lot of connected devices to support! Whenever I talk with customers about wireless deployments the first thing I will say when we get to the point of turning on a network is that the client will cause the best wireless network to fail. We always push to make sure that the latest drivers are applied to the devices going to be used to ensure proper roaming and performance. But how do you manage that when you have no control over the devices being used? In the future we’ll use tools like Cisco NCS and ISE, for now we just hope it works!
