I must stand corrected on the subject of six byte NIC addresses, it
is evidently much easier to spoof on all platforms than I thought
(we stop learning, we die). Fortunately, few are motivated to do
so and we can still use active hubs (except with coax) as a form
of control, it just will require cross-indexing. TANSTAAFL y'all.
On Covert Channels, I still believe that the term is best for a broad
class of attacks. It may be expanded somewhat from its original meaning
but language is a living artifact not a static one.
CC is not just a pair of words - "Squeamish Ossifrage" has no meaning when
placed out of context. On the other hand "Covert Channel" paints a mental
picture and helps *define* the problem: a mechanism for extraction of
information that is hidden. The term fits as nothing else in our lexicon,
even some of the published definitions fit, so why not use it ?
