What we did at another location was to run the network inside of piping
and the pipes were then pressurized. Then monitor the pressure.
Tapping the 'net without causing a drop in pressure was not trivial...
;-) YOu didn't mention the run.

Undeniably true, VPNs are part of the current trend towards defense in depth
that is required when you don't have a true solution.

This is not true. The US Navy did this to the Russians a few years
back.

I don't think you are remembering correctly. One reason for using fiber is
its security in that it gives off no electromagnetic field. In a typical
cable, the fiber is buffered by a vinyl sheath, and then in cheaper cables,
a simple exterior cable sheath is applied. It is impossible to "tap" the

In order to tap into a fiber line you have to break the sheath. The signal
is entirely optic, if you don't break the sheath you can't even see the
signal. However, even if someone does decide to break into it then they've
got another problem, exactly how to do it, it's extremely difficult because
According to our network people where I work there's currently no way to
splice fiber optic cable.
The two ways they mentioned (wrt monitoring fiber optic traffic) would
be to cut the cable and insert a transceiver in the line. The main issue
with this is that someone will notice the cable has
