Myth #6:A wireless IDS is unnecessary if other rogue AP

While exposing the myth about the prevention of rogue APs could be a blow to wireless IDS vendors, there is another common Wi-Fi myth that has been having the opposite effect. Many networking professionals are under the mistaken impression that a wireless IDS is unnecessary if other rogue AP prevention measures are in place.

It’s easy to understand why the average network administrator might be hesitant to get behind a wireless IDS. They are very expensive and there’s not a whole heck of a lot of folks out there who actually understand everything that a wireless IDS is doing. Even most of the folks who have invested in a wireless IDS only did so because they need to prevent rogue access points.

The reality is that there’s a whole other area of troubleshooting and Wi-Fi optimization features that make wireless IDS products a valuable addition to most networks. Some of today’s wireless IDS offerings do location tracking, remote packet captures, and analysis of RF interference levels.

When you think about it, these other wireless IDS features are much more likely to make a networking person’s job easier than the ability to neutralize rogue APs. Instead of having to send field technicians out to every location that has a problem, a wireless IDS allows the experts that own your network to troubleshoot the wireless medium from a centralized location.


One more thing to think about is the fact that so many Wi-Fi users are new to the technology. New users are often reluctant to report problems or call the support team. A wireless IDS may be the best way to find out if some area of a facility is likely to be unsuitable for time-sensitive applications like VOIP or video conferencing.

This myth about the ways the use a wireless IDS really has more to do with the performance of the network than the security of the network. Let’s look at three more myths that really touch on the performance of Wi-Fi networks.
