Question: What is a certified ethical hacker (CEH)? How to become a CEH?
Updated: February 26, 2024
Answer: Certified ethical hackers are cybersecurity professionals who have received intensive training and a formal certification in penetration testing computers and network systems to identify and address information security vulnerabilities. To become a certified ethical hacker, individuals must take and pass an examination offered through The International Council of E-Commerce Consultants, otherwise known as the EC-Council. In order to qualify to take the CEH examination, candidates must either have two or more years of experience in information security, or have attended a certified ethical hacker training program that has been approved by the EC-Council.
Certified ethical hackers (CEHs) play an important role in cybersecurity, as they are trained to conduct network systems security checks by hacking into authorized computer systems to find weaknesses that would otherwise be exploited by cybercriminals. Otherwise known as white hat hackers, offensive cybersecurity professionals (named as such due to the fact that their security tactics involve attacking systems to identify vulnerabilities), or Red Team professionals, CEHs are a crucial part of any cybersecurity team. Some of the key responsibilities of a certified ethical hacker include performing regular network scans for an organization, conducting network and computer systems attacks using common and emerging attack vectors, using viruses and malware to invade systems, completing vulnerability analyses, and developing recommendations and strategies to protect an organization from unauthorized intrusion and exploitation.
As mentioned previously, to become a CEH, professionals must take the CEH exam offered through the EC-Council. To prepare for this examination, students must have substantial professional experience in cybersecurity and ethical hacking, or else have completed formal training in the field. Students who want to gain training in certified ethical hacking have numerous options, ranging from courses offered through the EC-Council to CEH bootcamps offered by colleges and training organizations, cybersecurity graduate certificate programs that cover key CEH concepts and skills, and bachelor’s and master’s programs in cybersecurity with substantial coursework in certified ethical hacking.

- Completed an official EC-Council training in certified ethical hacking (these trainings waive the $100 exam eligibility fee), or received an earlier version of the CEH credential.
The Certified Ethical Hacker Examination
Currently in its 11th version, the EC-Council’s CEH Certification examination is one of the most established and respected cybersecurity credentials in the industry. Comprised of 125 questions, which students answer over the course of four hours, the EC-Council’s CEH examination covers the following categories, which the EC-Council refers to as Cybersecurity Domains*:
- Foundations of Information Security and Ethical Hacking: The CEH exam has 8 questions that cover information security standards and controls, ethical hacking concepts, and the cyber kill chain (which is the process of tracing every stage of a cyber attack).
- Reconnaissance Methods: The CEH exam includes 10 questions on footprinting (i.e. data collection and profiling) concepts and methodologies for search engines, web services, and social networking sites; DNS, network, and email footprinting; and footprinting tools and countermeasures. In addition, candidates answer 10 questions on network scanning processes and procedures; host, port, and service discovery; and 6 questions on enumeration (i.e., the counting of system/network vulnerabilities) concepts and countermeasures.
- System Hacking Processes, Procedures, and Techniques: Candidates are expected to answer 9 questions on vulnerability analysis techniques, including vulnerability classifications and assessments, vulnerability assessment tools, and reporting. This exam domain also includes 6 questions on system hacking concepts such as gaining and maintaining access, exploitation of vulnerabilities, clearing logs, executing applications, and cracking passwords. Finally, candidates must answer questions on different types of malware and their uses, malware countermeasures, and on computer viruses and worms.
- Networks and Perimeter Hacking: This domain includes 18 questions covering key concepts and techniques in sniffing (i.e. interception and/or theft of data using applications), sniffing countermeasures; social engineering (i.e. gaining the trust of targets so that they give up sensitive information); Denial of Service (machine and/or network shutdown) attacks and protective measures against them; session hijacking concepts, tools, and countermeasures; intrusion detection systems and their implementation; and evading firewalls and honeypots.
- Web Application Hacking: Candidates must answer 20 questions on web server concepts, web server attack methodologies and tools, patch management/software updates, web applications attacks and their countermeasures, and SQL injection types, methods, and tools.
- Hacking of Wireless Networks: The exam includes 8 questions on wireless network hacking, including the identification of wireless threats, wireless hacking tools and methodologies, Bluetooth hacking, and wireless encryption.
- Hacking of Mobile Platforms, the Internet of Things, and Operational Technology: This exam domain includes 10 questions on mobile platform attacks, hacking of iOS and Android OS devices, mobile device management, and mobile security guidelines, standards, and tools.
- Cloud Computing: The exam includes 7 questions on cloud computing concepts, threats, hacking, and security measures, as well as serverless computing.
- Cryptography: This part of the exam includes 7 questions on cryptography concepts, encryption algorithms, email and disk encryption, cryptanalysis, and public key infrastructures (i.e., the hardware, software, policies, and procedures used in the granting and management of digital certificates and public keys).
While the domains that the CEH certification examination covers remain consistent from year to year, the EC-Council is vigilant about updating the content of their examination to reflect evolutions in the industry. Currently, the CEH exam and its corresponding training programs offered through the EC-Council (see the below sections for more information) are in their 11th iteration, hence the designation CEH v11 that the EC-Council uses currently.
*Note: For more information on the above domains within the field of certified ethical hacking, please refer to our Cybersecurity Glossary, which defines terms discussed above.
The CEH certification is valid for three years from the date of the candidate’s successful passing of the examination; however, candidates can maintain their credential by fulfilling 120 credits’ worth of EC-Council Continued Education (ECE) over the course of three years. In summary, the path to becoming a Certified Ethical Hacker can be outlined as follows:
- Complete two years of professional experience in information security and cybersecurity, OR complete one of EC-Council’s official CEH trainings
- Complete an application to sit for the examination
- Take and pass the CEH examination
- Maintain one’s credential through continued education courses through the EC-Council
How to Prepare for the Certified Ethical Hacker Exam
As the above description of the CEH examination illustrates, this is a rigorous test that requires substantial preparation to pass. One of the most common ways to prepare for the exam is to enroll in the EC-Council’s own CEH training programs; however, several colleges and universities also have training programs and bootcamps that prepare students to sit for the exam. These programs can be a good option for professionals in the field of information security that already have at least two years of experience who would like to attend an exam preparation training program.
The Professional Experience Route: CEH Exam Preparation Materials and Programs
Many professionals working in the field of cybersecurity have formal academic training in cybersecurity or a related field, such as information technology, computer science, or engineering. There are numerous pathways to entering the field of cybersecurity, which include, but are not limited to, associate’s degree programs, bachelor’s degree programs, master’s degree programs, graduate certificate programs, and bootcamps in cybersecurity. There are also cybersecurity professionals who gained formal training while serving in one of the branches of the U.S. military.
Professionals with at least two years of experience, and who demonstrate competency in the cybersecurity field in their application to sit for the CEH exam, are not required to enroll in an official EC-Council training program. For these professionals, there are CEH study guides and practice tests that can be accessed online or purchased through a bookstore or Amazon.com. There are also online CEH training/exam preparation programs, online CEH bootcamps, and in-person CEH bootcamps offered by independent training providers. These intensive programs are often short in duration (five days is common) and have frequent start dates. The goal of these programs is to prepare professionals to pass the CEH exam.
Many online CEH training programs and bootcamps feature live online instruction; however, some are 100% asynchronous where students review course materials on their own time. These programs usually require students to complete the program within a specific time frame (e.g., six months), and students are able to interact with instructors through email if they have questions. Finally, some colleges and universities also offer CEH training programs and bootcamps through their divisions of continuing education. These may be a good option for students who feel more comfortable taking a training program offered by an institution as opposed to a training provider. For more information about cybersecurity bootcamps and how they can prepare students for certifications in the industry (including CEH certification), please refer to our FAQ on graduate certificate programs in cybersecurity vs. bootcamps in cybersecurity.
