CEH (Certified Ethical Hacker)

Certified Ethical Hacker (CEH) is a professional certification for cybersecurity experts who specialize in identifying weaknesses and vulnerabilities in computer systems. These professionals simulate cyberattacks in a controlled and legal manner to help organizations improve their security posture and protect against malicious hackers. The certification validates a professional's expertise in various hacking techniques and tools.

Example: A company hires a professional with a CEH certification to perform a security audit on their new customer portal. The CEH professional would use the same methods as a malicious attacker, such as trying to exploit a known vulnerability in the web server or attempting to bypass the login page using a brute-force attack. By finding and documenting these weaknesses, the CEH helps the company fix them before a real-world breach can occur.
