When you hear the words 'information security analyst', you're likely to think of a middle-aged man in a shirt and tie, hunched over a desk and looking miserable. That image may change dramatically when we tell you the more commonly-known title of this job - hacker. Thanks to Hollywood and tabloid newspapers, we know think of hackers as internet ninjas, breaking into people's computers and stealing money, pictures and whatever else they can find.
Obviously being a malicious hacker is a criminal offense, but companies who do business online (i.e., most companies) will sometimes employ 'white knight' hackers to attempt to break into their systems, and then provide reports about their security and possible vulnerabilities. In a lot of cases, such people are former criminal hackers who have changed their ways. Given how much they earn, they have no need for crime!
