Understand that hacking is not something that you can go to week long training session. It is a WIDE set of skills that covers a very wide set of conditions. Most people who “qualify” as hackers are at the very least, qualified as system administrators. That means a BEGINNING salary range of $35 to $60 thousand. Mid range or “certified” hackers can easily pull $80 to $100 thousand per year. Top end certified developers and network engineers make in the $150 thousand salary range. At the high end, an independent contractor that is certified and has several years of experience and has a clearance, can charge $250 PER HOUR.
To be an intelligence grade operation - i.e. no one knows that you are there and you leave no trace, you are going to need a TEAM - network, programmer, database admin, encryption, etc. The cost of such a team is beyond what most companies can afford.
Now add to the cost the fact that such skilled individuals should have at a minimum a level 2 security clearance (Secret) OR HIGHER. Those background investigations will need to be paid for as well.
I am not saying that it cant be done, but it is not like you can say “Go out and train 100,000 cab drivers to be truckers”. It is closer to say that you need to send 100,000 to get their associates degree, and of those, 30,000 need to go on to get a bachelors and about 5,000 need to go further and get their masters .... in hacking.
I took a course on using the Internet before most anyone had ever heard of it and I still don’t know what I’m doing.
