They do that too, but installing a tap at an exchange point that uses a shared media is as simple as wheeling in a Cisco chassis with a FDDI or Ethernet port on it. Not that the chassis necessarily contains any Cisco equipment, of course.

Fiber does make the eavesdropper's job harder but they don't necessarily need to tap 100% of the traffic to get useful data.

Obviously this German company is not aware of how the German intelligence service, in cooperation with the Israeli intelligence service, infiltrated a Swiss encryption company and crippled the encryption technology by not using all the bits of the key. This made the encryption crackable by the computers in use by the NSA at the time.

What makes you think that the NSA doesn't already have a solution to the DOS problem? After all, they've known about this stuff for about 20 years.
