Certified Ethical Hacker (CEH) is a qualification obtained by demonstrating knowledge of assessing the security of computer systems, answering multiple choice questions regarding penetration testing techniques. The code for the CEH exam is 312-50. Although the certification (and course) is referred to Version 10, the exam has not changed since v8, hence the exam code as remained as 312-50. This certification has now been made a baseline with a progression to the CEH (Practical), a test of penetration testing skills in a lab environment where the candidate must demostrate the ability to apply techniques and use penetration testing tools to compromise various simulated system within a virtual environment.
Penetration tests are employed by organizations that hire certified ethical hackers to penetrate networks and computer systems with the purpose of finding and fixing security vulnerabilities. The EC-Council offers another certification, known as Certified Network Defense Architect (CNDA). This certification is designed for United States Governmentagencies and is available only to members of selected agencies including some private government contractors, primarily in compliance to DOD Directive 8570.01-M.
