Batz,

I believe we are talking about two different perspectives here 
operational and end user.  The concern I have is with the ability of 
sectors dependent on information infrastructure to operate if there 
are problems.  What web-site is abvailable to the end user is not the 
value judgement but if NASDAQ can facilitate stock trades, if banks 
can clear settlements, etc.  

It does get a little fuzzy in what you consider Internet and what you 
consider private networks.  From a physical perspective they all use a 
common fiber infrastructure - it all runs in the same trench - so in 
some terms it does not matter.  There has been quite a bit of 
discussion about physical downage being an inconveniance, and if you 
limit yourself to just the Internet (web sites, email, porn, etc) this 
is a valid statement.  Where this goes off track is that the Internet 
is only part of the equation - the operation of several critical 
infrastructures is dependent on fiber based communications.  A cut is 
a cut - it does discriminate against private networks, security 
protocols, encryption or anything else.  A leased line does not mean 
you get a special ditch.

This happened recently  in Quebec where there is a labour
dispute with Videotron and one of the unions representing its 
workers.
The dispute has been exaserbated by the sabotage of the companies 
fiberlines. 

Now, while this may affect Videotrons bottom line, it only becomes 
a 
critical infrastructure issue when it becomes a Hydro Quebec 
issue, 
or it interferes with the provinces ability to deliver services. 

Honestly, if a few million people can't get their porn streams, the
world isn't going to end. If 911 operators, or ambulance services 
can't direct emergency crews for 10 people, then you have a serious
problem.

The What-If questions have to be sorted from a particular view, and
it will be the legislators view which will ultimately matter. You 
can bluesky, whiteboard, game and scheme all you like, but there are
only a few opinions that matter when it comes to deciding what 
is of importance to national security, and until we hear from 
them, 
we can be as paranoid and imaginative as we want, and it won't help
the infrastructure become more secure. 

So, as for Nasdaq, vs Google, vs the GSA vs Agriculture vs CNN, 
until we have the correct order in which to place these entities, 
we can't provide a useful or accurate model of how vulnerable the
infrastructure is. 

You mentioned that you thought Nasdaq would be the most important 
asset to protect, but what happens if some Internet 
traders on AOL can't make their trades because of a fiber cut, vs
not being able to get their infotainment from CNN, vs weather
and crop data data not getting to farmers on time. It's a relative
and ultimately political discussion.
