Subject: OT-- network security in big building

Hi All, Happy new year!

Recently I am working on a risk assessment for some branch offices for a
Company. Those branch offices are all located in a big/high building
around the world.

It seems pretty standard that each building has a communication room
that terminate the out side circuit and then extend the circuit to the
actual office location/floor.

I am curious that how can we trust a building's security system/policy.
Since most circuit will deliver internal traffic without encryption. It
is not that hard to tap a T1/E1 line at all.

 Any comments will be appreciated. I am wondering if this is the same
case everywhere.
