Okie dokie.

Not to belabor the point (or perhaps, *to* belabor the point), but when people think CIP these days (if they think of 
it at all) they think about the grid.  While it's nice that we have attention there, the fact that there is little or 
no attention in all of the other vulnerable sectors is a problem itself.

I disagree that the regularization plan (CIP itself) is any
good. 

I'm not likely to argue a whole lot on the detail side of things, but the overall direction of things is good (if 
painful).  Ten years ago virtually no-one (myself included) gave a half-thought to control system security, today there 
is a good bit of focus and more people qualified to cogitate on it.  External bodies are trying to develop standards, 
however ham-fistedly, that with a little luck and involvement will move in a positive direction over the long (maybe 
very long) term.

When I say "regularization" I don't just mean "regulation", I mean we need to make the process of addressing these 
facilities into a more regular and repeatable process and less of a custom one-off situation.

Yeah, I'd agree with the caveat that the standards be more
security-driven and less auditor-driven.

Ideally we can do both.  If you have really good security you can tell it is (otherwise how do you know?) and because 
you can you can prove it to someone else as well.

Ask Heartland about the difference between being able to show an auditor that you are "secure" at one point and 
actually being secure over time.  Ultimately regulations should/will evolve to include more real-time awareness, but 
today most folks don't have real-time situational awareness and most control system networks are effectively incapable 
of having it, so regulations won't require it.
