As more and more companies start to become confident that they can protect their customers' data from external threats, they will begin to turn that same scrutiny inward, experts say.

It's no secret that insiders pose a huge threat to companies. And as the economy lags and people get laid off or are asked to take over the jobs of employees who are, protecting valuable information becomes even more dangerous.

A perfect example is illustrated in the 1999 film "Office Space." A few freshly laid-off employees decide to retaliate by conspiring with some disgruntled insiders to hack the company's systems and steal from corporate coffers.
