A Certified Ethical Hacker is a skilled professional who understands and knows how to look for weaknesses and vulnerabilities in target systems and uses the same knowledge and tools as a malicious hacker, but in a lawful and legitimate manner to assess the security posture of a target system(s). The CEH credential certifies individuals in the specific network security discipline of Ethical Hacking from a vendor-neutral perspective.

It tests your skills in uncovering vulnerabilities that can be exploited by a malicious attacker. A CEH certification prepares you to match a black hat hacker’s techniques and creativity while equipping you with an in-depth understanding of hacking tools, evolving attack vectors, and preventative countermeasures.

Certified ethical hackers obtain permission from the asset owners before scrutinizing it for vulnerabilities and ensure that the outcomes remain confidential. The journey of becoming a certified ethical hacker begins with passing the CEH (ANSI) exam. Once you do, you can opt to take the CEH practical, a six-hour practical exam. When a professional is CEH certified and clears the CEH practical, they are recognized as a CEH Master.(Will Write my personal experience once completing the forth coming exams)

Ways to become a CEH

To become a certified ethical hacker, you need to pass the CEH exam that consists of a total of 125 multiple choice questions. You have a time limit of four hours to complete the examination.

EC-Council maintains the integrity of the certification exams by providing it as different question banks. These question banks are analyzed through beta testing for a suitable sample group under the supervision of security experts. It helps in ensuring that the questions asked in the exam have real-world applications in addition to academic significance. The governing body determines the difficulty rating of each question, and based on that, the cutoff is evaluated. Usually, it’s in the range of 60% to 80%, depending on the set of questions you get.


Eligibility criteria

Regarding the eligibility criteria for attempting the CEH certification exam, you have two options. First, you can complete an official EC-Council training at an accredited training center, approved academic institution, or via the iClass platform. In this case, you can challenge the EC-Council certification exam without going through the application process.

The second option for CEH certification eligibility needs you to have at least two years of experience in the information security domain as a prerequisite. If you have the relevant experience, you can submit your application along with a fee of $100 (non-refundable). In the application form, you’ll have to list your manager’s details, who would act as verifiers in the application process. The application usually takes around a period of five to 10 working days once the verifier responds to the EC-Council’s request for information.

Preparation Steps


Once you decide to achieve the certification, you need a concrete plan for training as well as practice. Choose the best source for training. Its highly recommend choosing offline classroom training if you are a student or novice in cybersecurity. Usually, you can complete training in 3-4 months or less. The reason for recommending an offline course is that meeting other like-minded learners and professionals will help you  develop the ethical hacker mindset. You can get in touch with proper mentors, people with similar mind-sets and take advantage of group study which can reveal many unknown issues, incidents, and examples. Of course, this will cost you more, but you can’t learn to swim without getting wet.

Get your hands on Experience with ilabs !

The plus point of the latest version of CEH v11 is that it is more focused,  practical based and scenario-based with the latest content that equips students with hands-on skills. Remember, security is all about practice and implementation rather than a bunch of documents and do’s and don’ts checklist. While gaining the credential you will learn about methods and tools that you can use to protect the organization such as security implementations, testing, and monitoring. Just bookish knowledge won’t help there. We recommend that spending at least 2 hours daily practice apart from training will improve your skills dramatically.

Study Guides 

While we did mention above not to be bookish, books are a treasure trove of knowledge and even for clearing the CEH you must do a thorough read of the recommended books.  You can religiously follow study guides and clear your concept on every topic in a very descriptive manner. This will answer all your “What and Why” in terms of cybersecurity and ethical hacking. Of course, this is world-class content and therefore you will get exact definitions, descriptions, and diagrams for almost all topics. We recommend studying at least 1 hour daily to get clear on all topics during the training. 


Study groups – Community

In my experience , i studied solely for day and nights nearly 4 months .Study groups will polish your knowledge and skills for CEH topics. There are many study groups you can join where you can resolve your queries, clear your doubts, take help to learn something, and help others too. This will help you to stay in the company of like-minded people and you will get to learn fast. 

It is recommended not to share any personal/sensitive information. Beware of any unknown person who asks for sensitive information like your IP address, location, personal information, or anything apart from CEH courseware.  

Its recommend making a study group with the people you know who are also attempting the exam. You can take the help of your trainer or mentor to manage this group. Be active and participate in group activities like quizzes or group discussions.


Keep learning is the key element of CEH training. Brush up your knowledge for the exam perspective as that is your main goal to become certified. For this, you need to learn how to give the exam and what type of questions are asked. You may face a lot of weird-looking or twisted or tricky questions with confusing multiple answers. Therefore, once you are done with your CEH training and you have knowledge of all topics, you need to test it like a mock drill of the war zone. There are many sources available where you can practice the exam questions. This platform will help you to understand the methods to ace the exam questions and complete them within the required timeframe.

Module 2 : Footprinting and Reconnaissance

Footprinting refers to the process of collecting information about a target network and its environment, which helps in evaluating the security posture of the target organization’s IT infrastructure. It also helps to identify the level of risk associated with the organization’s publicly accessible information. Footprinting can be categorized into passive footprinting and active footprinting:

  • Passive Footprinting:

Involves gathering information without direct interaction. This type of foot printing is principally useful when there is a requirement that the information-gathering activities are not to be detected by the target.

  • Active Foot printing:

Involves gathering information with direct interaction. In active foot printing, the target may recognize the ongoing information gathering process, as we overtly interact with the target network.

Module 3 : Scanning Networks

Network scanning is the process of gathering additional detailed information about the target by using highly complex and aggressive reconnaissance techniques. The purpose of scanning is to discover exploitable communication channels, probe as many listeners as possible, and keep track of the responsive ones.
