building" although the tempest (opps TEMPEST, sorry) testing was never
done on a "whole building" basis. That would have been fun to watch ;-)
Helicopters in your TEMPEST test plan anyone? yow! So calling the
building TEMPEST is certainly technically incorrect - but there is a
good amount of attenuation achieved, and that will make SCIF space
inside the (even if imperfect) faraday cage much more effective.
New construction made this possible - Building 1 and other "legacy"
buildings could never be modified to that level.
[And then there is the Colony 7 - the exact opposite of "TEMPEST" ;-) ]
One of the reasons that there are few buildings built with TEMPEST
type shielding integral to the building are that maintaining it,
fixing it, repairing corrosion (which is a huge issue) is very hard if
part of the building - but having the building be able to provide some
general attenuation is always a good thing.
- Somewhat, maybe completely, off-topic, I was in a band that traveled
from KC to DC in 1976 for a Bicentennial appearance at the Capitol and
White House. The Colony 7 was our "home base" for the stay. That was a
long ride on a Trailways bus. If I only knew then what I know now....
