Hacking Methodology Phases

Understand this attack lifecycle:

1. Reconnaissance

Gathering information about the target.

Passive: OSINT, social media, WHOIS Active: Port scanning, banner grabbing

2. Scanning

Identifying live hosts, open ports, services.

Tools: Nmap, Nessus, OpenVAS

3. Gaining Access

Exploiting vulnerabilities to access systems.

Techniques: Password attacks, social engineering, exploitation

4. Maintaining Access

Establishing persistent access.

Methods: Backdoors, rootkits, trojans

5. Covering Tracks

Hiding evidence of intrusion.

Techniques: Log manipulation, timestomping

CISSPSecurity managementExpert

CEH is broader but less hands-on than OSCP. Good stepping stone to advanced penetration testing roles.


Career Impact

Immediate Benefits

  • Role Access: Penetration tester, security analyst
  • Salary Range: $80,000-$120,000
  • DoD Compliance: Meets 8570 requirements

Career Pathways

Offensive Track:

  • CEH → OSCP → OSCE/OSWE

Management Track:

  • CEH → CISSP → CISM

Common Roles

  • Penetration Tester
  • Security Analyst
  • Red Team Member
  • Vulnerability Analyst
  • Security Consultant

Common Mistakes to Avoid

  1. Memorizing tools without understanding. Know when and why to use each
  2. Skipping hands-on practice. It dramatically improves retention
  3. Ignoring outdated content. CEH covers current threats
  4. Underestimating the exam length. 4 hours can be draining

The Bottom Line

The CEH certification at $1,199+ is a significant investment, but it opens doors to offensive security roles. Combined with hands-on practice, it provides a solid foundation for penetration testing careers.

Master the hacking methodology, practice with real tools, and understand the attacker mindset. Your ethical hacking career starts here.
