While Julian raises some good points about the statistical accuracy 
of *any* surveys, I would like to say that the results of CSI's 
survey match pretty closely with what we have seen in the field, so
I wouldn't toss the baby out with the bath water.

>From our experience:

o Most companies wouldn't know if they were broken into unless the 
   attacker were very stupid, very sloppy or just unlucky.  
   ("No amount of planning can ever replace dumb luck")  8^)

o The Access Control Mechanisms of most corporations are grossly 
   inadequate.  Case in point: any banking-by-phone systems where 
   you only have to enter your PIN # and the size of your last 
   deposit (gee, dial code, 2 nested loops, write the results to 
   a file & do the cleanup code - real rocket science).

o Most companies do *NOT* have good InfoSec (or reasonable facsimile
   thereof).

o Most external connections are either wide-open or have an extremely
   trivial authentication mechanism which could be bypassed in a couple
   hours (if you lost your decoder ring).

o The Operating System security is the same as when it was installed
   OOTB (Out Of The Box).  No alarms, no ACLs, & security turned off 
   by default.

o Most companies are very vulnerable to social engineering.

o Many companies (and state/local governments) are outsourcing their
   IT operations.  You can imagine how enthused the police departments 
   are about this proposition.  The possibilities for corruption/abuse
   just took a sharp turn in the wrong direction.

Pretty miserable state of affairs.  It is estimated that corporations 
will only lose >$10 Billion dollars due to hacking this year.  I wonder 
why.  Things are getting better, though.  The recent publicity about 
the Internet & hacking has caused many companies to wonder how good 
their security really is and to be genuinely concerned.  

Best Regards,


Frank
