Re: If they're so worried about wireless network security...
There's absolutely nothing wrong with SS7. Provided that absolutely everyone on the network is trustworthy, dependable, regulated, just like they used to be.
The problems only set in when some cheap arse network operators out there decided that running SS7 over Internet connections was cheaper than doing it properly, in effect giving world+dog access (with only moderate levels of hacking given how badly they're reported to have secured all this) to a network that was never designed to be secure against malicious network members in the first place.
What engineers create, accountants can destroy with the stroke of a cost saving. Bastards.
