For those of you who have followed my articles and rants, I've talked about baselining equipment now for many years. in this particular article, I will spend a little bit more time showing you how I baselined a webcam – yup another webcam - what it was doing, and how I reconfigured it to stop the unwanted traffic
A common question I get asked is, “How do you baseline wireless equipment?” You've got several options; you can obviously get a wireless analyzer and capture those packets over the air. Another approach is to work from the access points LAN side by using an inline analyzer between the access point and its switch port. Lastly spanning or mirroring that port to an analyzer works just as well.
It's important to remember that every piece of equipment on your network should be profiled or baselined. You should be familiar with what it should communicate with as well as what it is communicating with.
As I said in the video it doesn't matter if it's a refrigerator, a camera, or a thermostat. You should always find out how these devices behave because at some point you will have to troubleshoot them.
