Ethical hacking: What is it? A Complete Guide 2023

In 2023, there will be numerous institutes offering ethical hacking courses. This guide will assist you in understanding the basics of hacking and ethical hacking. It will provide a comprehensive overview of hacking courses, their tools, techniques, and various hacking courses available in 2023. But before understanding the terms ‘hacking’ and ‘ethical hacking,’ let’s discuss what it means and how you can become a certified ethical hacker.

What is Ethical Hacking?

Ethical hacking systematically tests and evaluates a computer system, network or application to identify security vulnerabilities that an attacker could exploit. Ethical hacking aims to improve the enterprise’s overall security by exposing potential threats that malicious hackers might otherwise use. In addition, organizations can deploy strategies to protect their sensitive data from unauthorized access by finding and analyzing these potential security weaknesses.

History of Ethical Hacking

The concept of ethical hacking originated in the 1990s as a response to the growing number of malicious hacking attacks on networks and systems. In 1998, the Department of Defense created the Certified Ethical Hacker (CEH) program. This program was designed to help organizations secure their computer infrastructure by assigning security professionals with hacking skills to test their networks and applications against potential attackers.

Tools Used in Ethical Hacking

There are various tools available for performing ethical hacking. Some popular tools include port scanners, vulnerability scanners, packet analyzers, password crackers, wireless hacking tools, and honeypots. Each tool has its purpose and can be used for different hacking activities. For example, port scanners are used to scan ports on a target system. On the other hand, vulnerability scanners are used to detect security flaws in a system.

Which Ethical hacking course do you need to choose?

The answer depends mainly on your current skill level and what you hope to accomplish with ethical hacking. An introductory course may be the best option if you are a beginner. This will give you an overview of the fundamentals, such as security protocols, penetration testing, and defensive strategies. 

You can also choose courses that focus specifically on one area of ethical hacking, such as web application security or network security. Suppose you have some experience and want to take your skillset to the next level. In that case, more advanced courses are available that cover topics such as reverse engineering, malware analysis, and digital forensics. Ultimately, it’s important to pick a course that fits your current level and helps you reach your goals. here read more about top 10 best hacker tv shows and series.

Some of the ethical hacking courses include:

  • CEH (Certified Ethical Hacker) Certification
  • Security+, OSCP (Offensive Security Certified Professional)
  • CISSP (Certified Information Systems Security Professional)
  • SANS GIAC Certification

Each ethical hacking course has unique topics and objectives that should be met before obtaining certification. Additionally, most courses require applicants to pass an exam or complete hands-on activities to receive certification.

How Do You Become an Ethical Hacker?

To earn a cyber security certification, many individuals have computer science or electrical engineering degrees to assist them. However, having several years of experience as an IT security professional or programmer is also beneficial. Additionally, gaining knowledge and understanding the importance of data privacy are necessary skills for anyone wanting to pursue this profession.

Many ethical hackers are self-taught, honing their skills through independent learning and experimentation. However, employers typically favour candidates with formal training in ethical hacking and academic credentials.

Skills Required to be an Ethical Hacker

1. In-depth knowledge of computer networks, hardware, and software systems.

2. Ability to identify security threats and vulnerabilities and implement countermeasures to protect data.

3. Proficiency in coding languages such as HTML, Java, PHP, and SQL.

4. Experience in using penetration testing tools to evaluate system security.

5. Comprehension of ethical hacking principles and techniques.

6. Knowledge of risk management procedures used to mitigate potential risks.

7. Excellent communication skills (verbal & written) for reporting results to stakeholders.

8. Understanding of digital forensics techniques used for criminal investigations.

Advantages of Having Ethical Hacker Certification

1. Improved credentials – An ethical hacker certification demonstrates your commitment to the security of data and networks. This gives you an edge over other IT professionals who don’t have such qualifications.

2. Increased earning potential – With knowledge and experience in ethical hacking, you can command higher salaries, as employers will be willing to pay more for someone with these skills.

3. Improved job opportunities– An ethical hacker certification opens various career options by giving you access to jobs requiring digital security expertise.

4. Up-to-date knowledge – With regular training and certifications, one can stay ahead of the curve regarding technological advances and cybercrime trends. This allows them to acquire more knowledge and stay in touch with the latest security practices.

5. A stronger network– Participating in ethical hacking training programs and forums allows you to build relationships with other ethical hackers. This creates an invaluable network of contacts who can offer advice and support throughout your career.


The field of ethical hacking continues to evolve, with new threats and technologies emerging every day. As such, organizations must stay ahead of the curve by training their security professionals in ethical hacking courses and using the right tools to protect their networks. Through proper education, certification courses, and tools such as port scanners, vulnerability scanners, and password crackers, aspiring ethical hackers can become certified professionals and bring value to any organization.
