by my definition,  an outsourced "security and ids" is already
a breach of security ... period ..
	- unless that outfit carries e/o insurance for say
	enough to cover damages and losses from a breach
	from hackers and other un-permitted activities
	( insurance like what counterpane carries in the $xxxM 
	( when they do some security work

you really do not want "brain cycles" to do montioring ( very bad idea )

but you really do want brain cycles to define the security policy 
and how people and machines get to do certain tasks

-- everything should be automated ... not brain cycles ..
	- brain cycles goes on vacation
	- brain cycles gets sick
	- brain cycles go home after 8 hrs
	- brain cycles gets distracted for other things
	- brain cycles are only as good as they wanna be
 	...

- a good hacker/cracker just needs a few seconds/minutes
  to do what they need ... ( but depends on what it is that
  we're trying to prevent too vs receover from said activities )

	-- i prefer my custom tools that md5 all the stuff
	i care about

counterpane carries e/o for encryption technology etc
and not sure if they also have the same for ids type of security
