Many people often blame so called hackers for intruding there systems.  However, in many cases (not to say most), they can only blame theirself for installing and implementing ‘immature’ security systems.  Most of the so blamed ‘hackers’ are curious kids that read some information about security (as it is widely available on the internet) and are messing around a little.  They rarely have malicious intentions.  If they get in, start by improving your security system instead of blaming them.  I’ve seen solutions provided by ‘professionals’ working for famous consultancy companies, that provide security systems even a 6 year old can bypass.  If you see the fees charged for these applications, you’d rather consider sueing the consultancy company then the intruder.  Maybe something to think about: if a real hacker would want to harm you, you’d never know it before the damage is irreversible !
