I hope that Behringer tech support is reading this, and realizing that if they are unable to add security to the X32 - iPad link, they should at least make sure the users realize it's unsecured and recommend some security steps.
The desk can be connected to a network, but that network is the responsibility of the person who set it up and with the equipment they set it up with. The X32 has no wireless capability out of the box. You need to add hardware to it to do that.
Securing the network at the router should be sufficient.
Hiding the SSID should be sufficient.
Using WAP2 should be sufficient.
Using a MAC Access Control List on the router should be sufficient.
If someone is that determined to wreck the show, they'll do it, regardless of how you've secured your network.
In fact, your average punter won't need wireless access to the desk to kill it. Just give them a hammer/chair/blunt object and watch how they bring your show to a halt in seconds.
That said, with everything being software driven, and running over IP anyway, maybe something could be put into the desk so that it only responds to commands from specified MAC addresses. If you set the device pairing/allowed devices in the desk, that should lock it down completely.
You would have to be up against a very serious hacker for them to be able to
1) work out the SSID of your network
2) get around the WAP2 encryption
3) identify the MAC address of your iPad
4) spoof it on another device
5) connect to your network
If that ever happens, you at least have the option of pulling the network cable and working from the surface, but not before the hacker has had a bit of fun muting things, etc.
While you guys are having this hypothetical discussion, someone just broke into your storage and stole all your X32s.
I understand that not everyone knows how to setup a wireless network the way we (most of us) know how to tie our shoes. I would argue that if you want to use the tool, you should read up a bit on it. It isn't a technology that is going away in live sound any time soon.
Also, Behringer can't put anything into the mixer because doing so would lock them into a specific wireless technology ..... which like the products I develop, they have no desire to do.
By limiting themselves ONLY to a basic wired ethernet jack, they are automatically able to handle future wireless upgrades as they come along. So far we have had the following list of wireless specifications:
- 802.11g plus or super g
- 802.11 - 2007
- 802.11 - 2012
As you can see, what ever standard you can buy in a wireless router today, will soon be obsolete. While we expect our mixers to last >10 years, I can guarantee you will NEVER find a wireless specification that lasts that long
The way the X32 is setup now, if you want to take advantage of a better wireless technology when it comes along, all you have to do is replace your router (these are cheep and run between $60-$200).
Finally, the idea that anyone with the know how and equipment to hack a WPA2 connection would waste their valuable time and effort ruining someones show who was using an X32 is really silly. It isn't fast or easy to do, and anyone that could do it wouldn't be interested in it.
On an entirely different angle, if at all possible you should use 5Ghz wireless routers to avoid the cluttered 2.4Ghz range which every kid with a cell phone will be pounding as well as every local wireless network near by. This is also a setting inside your router. The 5Ghz frequency will be much less likely to be bogged down, but has less range than the 2.4Ghz frequency. YMMV. The iPad 2 and 3 have this I believe, but the iPod touch may not.
