Why the hell would they teach you all that? Are they trying to make more hackers and stuff? O.O
Because not all hackers are bad?, and they need people that can build secure features in just about everything. And they need people to be professional hackers so they can test out the security of a thing and make it even more secure.
Say
Programmer A builds a firewall to protect Secret Government Files.
If Programmer B tries his Hardest to Hack it using his security hacking skills and fails.
Programmer A;s firewall is good
If Programmer B can get at the Secret Government Files then It's clearly a bad security system.
Being a professional Hacker is a real thing, and they really aren't all that bad.
