CEH v4 Domain #4: Network and Perimeter Hacking

November 25, 2021 by Greg Belding

Organizations that want to maximize the chances of not being another statistic of malicious hacking can hire a certified ethical hacker. These “white hat” hackers test an organization’s systems, networks, and overall information security. The Certified Ethical Hacker, or CEH, certification is a well-renowned cert that verifies the knowledge and skills of these “white hat” heroes.

The CEH certification is currently on Exam Blueprint v4.0, which has brought some changes to how the Domains of knowledge are presented. This article will detail Domain #4 of CEH Exam Blueprint v4.0, Network and Perimeter Hacking. It will explore what the CEH certification is, changes since the last exam version, the target audience, and the content that domain #4 of the CEH exam certification will cover.

What is the CEH certification?

The CEH certification verifies that the holder has a practical understanding of the phases of ethical hacking, the various attack vectors, and the preventative countermeasures used by ethical hackers. It certifies that the holder knows how to think and act like a malicious hacker to better position your organization’s information security measures and better defend against real-world attacks. It is premised on the idea that if you understand vulnerabilities and system weaknesses your organization faces, you can better strengthen system security controls in the face of malicious activity and attacks.

Who is the target audience for CEH?

From a high-level view, any information security professional wants their organization to be better positioned in the face of attacks and malicious activity. Below is a list of roles that typically earn this certification:

  • Information Security Analyst
  • Information Assurance Security Officer
  • Information Security Manager/Specialist
  • Information Systems Security Engineer/Manager
  • Information Security Professionals/Officers
  • Risk/Threat/Vulnerability Analyst
  • Information Security/IT Auditors

What has changed since CEH Exam Blueprint v3?

They say that the only thing constant in life is change and this saying applies to the new CEH Exam Blueprint. Normally, I offer a side-by-side comparison of the old and new exam versions, but in the case of CEH, so much has changed we will keep it brief. Domain #4 of CEH Exam Blueprint v3.0 was entitled “Tools/Systems/Programs,” and it consisted of three subdomains, making up 28.91% of CEH exam content and accounting for a whopping 36 exam questions.

In CEH Exam Blueprint v4.0, Domain #4 is now titled “Network and Perimeter Hacking,” which covers 14% of CEH exam content and represents 18 of the CEH certification exam questions. The five subdomains of domain #4 are as follows:

  • Sniffing
  • Social Engineering
  • Denial-of-Service
  • Session Hijacking
  • Evading IDS, Firewalls, and Honeypots
