I think TEMPEST eavesdropping has very limited value with today's low
rad monitors.  The monitor has always been the traditional target for
this activity.  When TEMPEST first became widely known, the CRTs were
much easier to rasterize.  Today that is not the case, although some
people still say that their devices can intercept upto 1KM, I would
guess it is more likely a few feet.

Just a thought I had while on a nicotine-and-caffeine break:

Has anyone ever done a bit of Van Eck (aka TEMPEST) surveillance as
part of
a penetration test, just to show people what can be seen from a van
in the
corporate parking lot when the security attendant is on his lunch
break?
That could provide a few hot debates in boardrooms, especially if one
were
to tune in to the Internet browsing habits of a few senior
directors...

Has anyone done it, or had/seen it done (esp. outside of a military
environment)? Are there any good references around re. proposed
civilian
standards for 'safety' from Van Eck scanning? And where would one
look
around either for people who do that type of surveillance, or the
equipment
to do that with.

And, finally, if this is not the right forum for such discussions,
could
anyone in the know point me to such?

Very ta,
