Certified Ethical Hacker (CEH) Certification Guide

By Ethical Hacker Certification Guide

The term hacker has traditionally had a bad reputation with many people as it brings up feelings of being exploited or having ones privacy breached. As with anything in life, there is always going to be the bad with the good and in the world of network security there are always going to be individuals, organizations and countries looking to gain access to the secret information of their opponents.

The purpose of the Certified Ethical Hacker certification is to validate the credentials, background and intentions of a network security professional. These professionals have the knowledge and ability to breach the security of a target for malicious purposes but instead of using these abilities maliciously they use them to increase the security of a network. This article provides an overview of the Certified Ethical Hacker (C|EH) certification, how it is structured and the steps that need to be followed to obtain it.

C|EH Certification Review

As stated in the overview, the purpose of the C|EH certification is to provide candidates a way of validating their abilities as well as their intentions. By obtaining the C|EH certification, a network professional can show prospective employers or clients that their intention is to use their abilities to increase the security of a system and/or network and not to decrease it. By having a formalized certification that can be offered to companies, the C|EH also establishes that hacker is not a term that is only associated with negative actions.

To obtain the C|EH certification, a candidate must pass the current version of the C|EH exam, as of this writing the current version is v8. The C|EHv8 exams consists of a proctored computer exam which contains 125 multiple choice questions which the candidate has 4 hours to complete and must obtain a score above 62% to pass. However, not just anyone can just go out and study and take the C|EH exam; before a candidate is allowed to schedule the exam they must be deemed eligible.

There are two ways to become eligible to take the C|EH exam:

  1. Attend an official C|EH instructor led course, computer based training (CBT), online live training or academic learning
  2. OR

  3. Submit an eligibility form and be manually approved to take the exam, to be approved a candidate must:
    1. Have at least two years of information security related experience.
    2. Remit a $100 non-refundable eligibility application fee
    3. Submit a completed exam eligibility form.

C|EH Exam Layout

The C|EH exam is structured into seven different sections; I have listed them in order of weight (shown in %):

1.Tools/Systems/Programs (32%)

  • NIDS, HIDS, ACL, DNS
  • Programming and scripting languages
  • Cryptography techniques
  • Port scanning
  • Network topologies

  • Routers, modems, switches
  • Operating environments and antivirus systems and programs
  • Log analysis tools
  • Security models
  • Exploitation tools

2. Security (25%)

  • Network and physical security
  • Biometrics
  • Firewalls
  • Threat modeling
  • Systems security controls
  • Application/file server
  • Cryptography
  • Verification procedures
  • Social engineering
  • Vulnerabilities

3. Procedures/Methodology (20%)

  • Cryptography
  • PKI, SA
  • Security architecture and testing methodology

Summary

Whether the term hacker will ever be used by the larger population with both a positive and negative meaning will be seen over time. The C|EH certification provides a process of allowing these network security individuals to validate their abilities and their intention to use them for the good of a company or client.
