Panopticon
I worked in SWIFT and they are pretty unhackable. In my place they had one internet connected PC, not connected to any other internal computer and with it's drives removed and it's ports literally cut out. Plus it was on CCTV, as were most places there. And they analysed your toilet material for drugs or whatnot. And body scanners at the door to check you weren't taking or bringing CDs or drives.
Every security scare about SWIFT is always about the banks that connect to it, it itself is pretty much the perfect panopticon.
