Actually I read every post before I responded to yours.  Yours made utterly no 
sense in the context i was in at the time.

I am saying that first and foremost, physical security is the foundation of 
all security.  If the place where the box lives is not secure, you can add as 
much fancy shmancy crap you want, it will not matter, someone who wants your 
data badly enough will just take your box.   Is that clear enough for you, or 
do I need to word it more simply?  

You know what, kiss my ass.  Go ahead find a place to hire you, get 8 or 9 
years of experience with security and then we'll talk.

Actually, you were talking about doing this professionally.  Look at it this 
way, any of that crap happens, you will find it pretty friggin quickly.  You 
do that, you rebuild your box, and then you're done.  Odds are you'll not be 
hit again.  No one I personally know has been hit by a hacker in that way, 
and no one I know has done anything beyond really simple crap like securing 
services that takes perhaps 15-20 minutes.  Then look at all the time you 
spend at it going beyond that, compare it with the time you spent building 
your system in the first place.  For me, that's pretty solidly more time 
spent actually securing the thing than building it(and doing such small 
things as turning off services and running strobe against the system to make 
sure unnecessary crap is off.)  I think for the vast majority of people out 
there, it would also be skewed that way.

Only if they want your data.  The only reason I'd be concerned about my system 
is for the data on it.  Someone hacks it, OK, fine, I load a CD, spend 10-15 
mins setting up the install, go off for a half hr, and come back.  Done.  
Load a second CD, launch a script, go to the movies, come back, Done.  have a 
nice new hot system, minus my data(important stuff is backed up to CD.)  I 
have perhaps 30 minutes on that, perhaps another 30 minutes to make sure its 
all pretty, and I am done.  Can you do a really good job in securing a system 
in an hr?  I doubt it, and if you could, you're missing something.

Again Pete, I suggest you get something called real world experience before 
you say that.  First year or two, you learn about the crap you really have to 
worry about vs the crap that's irrelevant.  

Good day.
