I know security is important to any business or individual. We spend so much computing power to combat malware, ads, etc. One of the best Certifications for the security professional is one from the EU Council, called the Certified Ethical Hacker.
It tests users on their ability to hack, configure port scans, perform network diagnostics, etc. It involves actual hacking, not just a question-and-answer as so many others do. I scored 92 out of 100 on it! See if you can do better!
