As a veteran who currently works in cybersecurity, I can say that there are a couple of factors that need to be considered.
First is the lingering misconception that a hacker makes a good cybersecurity professional. That is simply NOT the case. Yes, there is an area where a hacker can provide useful skills regarding security controls, but that is only one aspect of what it takes. Other considerations are morals so that the attacker knows the difference between what they can do, should do, and are authorized to do. This means that the ideal candidate for training in Cybersecurity is NOT the kid off the street. The more likely candidate is someone who has been promoted a couple of times, has a security clearance and already has experienced working in IT operations.
