How familiar are you with the ins and outs of ethical hacking? Let's find out!

IT-related security is a topic that increases in importance each and every day, and newly uncovered flaws routinely make the evening news. Sometimes there are weaknesses discovered in software that can be exploited and allow a miscreant to access information they should never even know exists. Other times, social engineering can be misused to trick individuals into divulging information they should not.

In this world of weaknesses, the role of the ethical hacker is central: Someone needs to identify the vulnerabilities before the miscreants do. A number of certifications have cropped up in recent years to authenticate this knowledge and identify a core set of skills.
