Ethical hacking – defined "methodology adopted by ethical hackers to discover the vulnerabilities existing in information systems' operating environments."

In their search for a way to approach the problem, organizations came to realize that one of the best ways to evaluate the intruder threat to their interests would be to have independent computer security professionals attempt to break into their computer systems.

Who is an Ethical Hacker?
The Ethical Hacker is an individual who is usually employed with the organization and who can be trusted to undertake an attempt to penetrate networks and/or computer systems using the same methods as a Hacker.

What do hackers do?
An ethical hacker's evaluation of a system's security seeks answers to these basic questions:
What can an intruder see on the target systems?
What can an intruder do with that information?
Does anyone at the target notice the intruder's at tempts or successes?
What are you trying to protect?
How much time, effort, and money are you willing to expend to obtain adequate protection?


Several hack attacks are on the media, those attacks wouldn't have occurred if there hasn't been a loop  hole, that is why an ethical hacker is required to access your loop hole and recommend the best solution, after it has been resolves will re analyze the systems, or application involved.  All required to know about how to enhance their security, the only person exempted is a toddler and a small baby.
