Certified Ethical Hacker (CEH) is a qualification given by EC-Council and obtained by demonstrating knowledge of assessing the security of computer systems by looking for weaknesses and vulnerabilities in target systems, using the same knowledge and tools as a malicious hacker, but in a lawful and legitimate manner to assess the security posture of a target system. This knowledge is assessed by answering multiple choice questions regarding various ethical hacking techniques and tools. The code for the CEH exam is 312-50. This certification has now been made a baseline with a progression to the CEH (Practical), launched in March 2018, a test of penetration testing skills in a lab environment where the candidate must demonstrate the ability to apply techniques and use penetration testing tools to compromise various simulated systems within a virtual environment.
Ethical hackers are employed by organizations 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 Government agencies and is available only to members of selected agencies including some private government contractors, primarily in compliance to DOD Directive 8570.01-M. It is also ANSI accredited and is recognized as a GCHQ Certified Training (GCT).
