"It is older, organized criminals that are actually the real problem, but 15-year-olds can still do a lot of damage and they're not to be taken lightly. When they are 15, that just means they are more reckless and don't really have a sense of which direction they are headed in, which can be a very serious threat for companies," Calce explained.

Calce suggested organizations hire outside penetration testers to make sure their networks are secure.

"A lot of companies don't even bother getting penetration testing, which in this day and age is starting to become a detriment to their company because as soon as you get compromised, your credibility as a company or corporation as a whole can shut down in a matter of minutes," he said.

When asked what he would do if he were an IT manager, Calce said his first priority would be to stay on top of everything.

"Knowledge is power in this industry," said Calce. "The more you know, the better off you'll be ... the idea is to stay on top of everything that's being realized for that operating system. The No. 1 thing I would do is stay on top of all the latest patch nodes and updates that are coming out for the operating system that the company would be running."
