Certified Ethical Hacker (CEH)

1 Global Definition

The Certified Ethical Hacker (CEH) is a professional cybersecurity certification? offered by the EC-Council?. It validates a candidate’s knowledge of ethical hacking? techniques and tools used by malicious hackers, but applied in a legal and authorized way to help organizations secure their systems.

1.2 Why It Matters

The CEH certification is recognized globally as a standard for professionals in the penetration testing? and security auditing field. Holding CEH demonstrates that the individual can think like a hacker and use the same tools and techniques, but within a legal and defensive context. Many employers require CEH for security-related positions.

1.3 Key Domains Covered

• Information Gathering & Reconnaissance: Techniques like footprinting? and scanning.
• Network Scanning & Enumeration: Using tools such as Nmap?.
• System Hacking: Password cracking, privilege escalation, malware, and backdoors.
• Web Application Attacks: SQL Injection, XSS, CSRF, etc.
• Wireless Attacks: Exploiting WEP/WPA and rogue access points.
• Cryptography: Understanding encryption, hashing, and digital signatures.
• Malware Analysis: Viruses, Trojans, worms, and evasion techniques.
• Cloud Security & IoT: Security challenges in modern environments.

1.4 Exam Details

• Exam Code: 312-50 (latest version: CEH v12)
• Duration: 4 hours
• Format: 125 multiple-choice questions
• Passing Score: Between 60%–85% (depending on difficulty level)
• Delivery: Online via Pearson VUE? or at EC-Council testing centers.

1.5 Career Benefits

• Qualifies for roles like Security Analyst, Penetration Tester, SOC Analyst, and Cybersecurity Consultant.
• Recognized by government and defense organizations worldwide (DoD 8570 baseline requirement in the U.S.).
• Enhances credibility and earning potential in the cybersecurity field.

1.6 Study & Preparation Resources

• Official CEH Courseware: Provided by EC-Council.
• CEH Practical Labs: Hands-on labs simulating real-world attacks.
• Tools like Metasploit?, Nmap, Wireshark, Burp Suite, John the Ripper, Hydra.
• Books such as “CEH v12 Certified Ethical Hacker Study Guide.”
• Practice exams and CTF (Capture The Flag) challenges.

1.7 Practical Example – CEH Knowledge in Action

Example: During a penetration test, an ethical hacker uses Nmap? to find open ports on a target system:

  nmap -sV -p 21,22,80,443 target.com
  

The scan reveals port 21/tcp (FTP) open. The tester then tries hydra? to test weak FTP credentials:

  hydra -l admin -P passwords.txt ftp://target.com
  

If successful, this shows the client that their FTP service is vulnerable to brute-force attacks and needs stronger authentication or account lockout policies.
