Even mundane day to day tasks rely on the use of computers. Technology is evolving at an unprecedented rate and as a result the products that reach the market are engineered more for ease of use rather than secure computing. With the increased numbers and expanding knowledge of ill-intentioned crackers, combined with the growing number of system vulnerabilities and other unknowns, organizations (universities, corporate companies, NGOs, hospitals etc) need to be more proactive in securing their sensitive networks and data. More and more companies now believe in the quote: "To catch a thief, think like a thief" and hiring ethical hackers to ensure information system security.
For a long time, the term Ethical Hacking has been termed to be an oxymoron. This is mainly because of the misappropriate information imparted by misinformed or more appropriately, 'lesser informed' people.
Since a long time, zealous and intelligent information system professionals who can get around a computer issue through innovation have categorized themselves into two categories: Black Hat Society (Crackers) and White Hat Society (Hackers).
