They have respectively four and zero parentheses.

Hey, the server was down! :-( :-D

The OP's question is really out of regulations of c.l.j. That is the

famous "acceptable potential hackers" dilemma. Any system is vulnerable

by default to N amount of experienced hackers (a system vulnerable to 0

hackers cannot exist by thermodynamic laws). More robust the system -

lesser the N number. As hackers as human being cannot be fractional

(0.5 hacker cannot be), the system lims to Super System - Super Hacker

solution. So eventually the equation solves to one absolutely

unbreakable system and the only one person able to hack it. If such

person appears to be a law-obeying member of the socially the equation

will be solved by non-mathematical methods. Otherwise your only

solution is to decide what N% is acceptable for your current situation.

Every 2nd? No more than half? 1% of your visitors? For the last the

proposed measures are good enough.

P.S. Super Hacker theory is taken from the black hackers' bible, which

I never saw of course. Just rumors.
