Modern computer systems are complex. With great complexity comes great vulnerability.
There is an attack/defense asymmetry:
A chain is only as strong as its weakest link.
To win, the defender has to block every attack.
To win, the attacker has to succeed just once.
Even good defenses fail!
Don't do anything illegal!
NEVER EVER EVER EVER EVER hack into a system that you do not have explicit permission to hack.
Never attempt to find vulnerabilities in a system that you do not own or have permission to audit.
