Network admins and other IT functionaries will go the way of the ones who thought they were set for life in the early to mid '90s when regular users began developing similar skill sets. security is probably one of the areas that will keep evolving and expanding - look at how many big breaches have occurred in companies that should have known better and been prepared. As hackers get more and more innovative, security folks will have to adapt.
That happened while I was at Cal State as a Computer Information Systems major. Business owners were installing and maintaining their own information systems and the "professional" market just wasn't there. It happened very fast.
One of my programming teachers said a programmer could write his own ticket. Five years later programmers in the US were unemployed and programmers in India were doing the same work for five bucks an hour.
Thanks for the advice.
Where might one go to find training in system security? Is that a tech school curriculum?
