>Although it's really outside the scope of this book, it's
|
|
important to remember that computing and communications equipment leaks a lot
|
|
information that makes them hard to really secure.
|
|
Many people are aware of TEMPEST requirements which deal with
|
|
radio frequency emissions of computers, displays, keyboards, and other
|
|
components which can be eavesdropped.
|
|
The light from displays can also be eavesdropped, even if it's bounced off an
|
|
office wall at great distance
|
|
[Kuhn 2002].
|
|
Modem lights are also enough to determine the underlying communication.</P
