The Certified Ethical Hacker is a professional certification provided by the International Council of E-Commerce Consultants (EC-Council.)
An ethical hacker is usually employed by an organization who trusts him or her to attempt to penetrate networks and/or computer systems, using the same methods as a hacker, for the purpose of finding and fixing computer security vulnerabilities. Unauthorized hacking (i.e., gaining access to computer systems without prior authorization from the owner) is a crime in most countries, but penetration testing done by request of the owner of the targeted system(s) or network(s) is not.
A Certified Ethical Hacker has obtained a certification in how to look for the weaknesses and vulnerabilities in target systems and uses the same knowledge and tools as a hacker.
The exam code for C|EH is 312-50. The certification is in Version 7.1 as of 14 June 2011. A version 8 has later been added.
