What's the alternative, you ask? Instead of time slicing, you can use dedicated sensors. These sensors scan the network 24 hours a day, 7 days a week, 365 days a year. There are two types of dedicated sensors, embedded or overlay sensors.
Embedded sensors utilize an additional radio within the same AP/device. Embedded sensors report to the same WLAN controller and/or management platform that control the access point radios responsible for serving client access.
Overlay sensors on the other hand are separate devices, often from a different manufacturer than that of the Access Points. Overlay sensors usually report to their own separate server.
Personally, I prefer embedded sensors as they cut down on the number of cable runs, switch ports, installation time, etc. Using APs and sensors from the same manufacturer also has some advantages when it comes to a single point of support, lower maintenance costs, etc. However, the most important point here is to use dedicated sensors of any type instead of using a wireless intrusion detection system that leverages time slicing.
Well, that's it: excessive SSIDs, "hiding" the SSID, and time slicing wireless intrusion detection. What dumb mistakes do you see network administrators make when configuring a wireless LAN? Let me know by submitting a comment in the section below!
