The internet and technological advancements have now reached even the most remote corners of the globe. We exchange information and data online, whether it’s photos or sensitive work documents. Without a question, technology has made our lives simpler. It does, however, have a negative aspect. Because a large portion of our sensitive data is stored on computer systems, applications, and networks, and hackers can steal, distort, and modify it.

The act of uncovering weak areas in a network or computer system to break it and obtain access to vital data is referred to as hacking. Cybercrime has seen a significant rise. Because technical advancements are also devising various viruses and spyware that threaten our security networks, we need hackers to protect our systems from cybercriminals. This is when ethical hackers come into the role. 

In this article, we will discuss who are ethical hackers and what they do, how they detect vulnerabilities, and forecast intrusions before it’s too late. 

Who is an Ethical Hacker?

Ethical hackers are skilled hackers responsible for safeguarding computer systems and networks from harmful or unethical intrusions. They use their abilities to discover existent security flaws and prevent unethical hackers from breaching organizational systems and gaining access to sensitive and confidential data.

The key distinction between an ethical hacker and a malicious hacker is that an ethical hacker protects data against misuse and protects weak points in the system. They are an important component of any organization’s operational security team and have accessibility to other’s computer systems to ensure optimal data security.

An ethical hacker, often known as a White-Hat Hacker, is a security expert. Ethical hackers employ their expertise ethically and legally to assist in the discovery and improve weaknesses in a system before criminal hackers uncover them and breach in.

Ethical hackers look for the following vulnerabilities in a system or network:

  • Injection assaults
  • Sensitive data exposure
  • Security settings modifications
  • Validation protocol vulnerability
  • Components that serve as access points

What Does an Ethical Hacker Do??

Ethical hacking, often known as penetration testing, is a type of data security. Businesses and organizations employ ethical hackers to optimize their applications, systems, and computer networks to avoid data fraudulent activity and theft. Ethical hackers assist businesses in many ways, including the following:

  • Recognizing Weaknesses

Ethical hackers help organizations in identifying which of their security procedures are successful, which require upgrading, and which include exploitable loopholes. When ethical hackers finish their evaluation of a business’s networks, they report to corporate management on any loopholes that lack adequate password encryption, unsecured apps, or vulnerable systems running unencrypted software. The results of these tests are used by organizations to make knowledgeable decisions about where and how to strengthen the security infrastructure to prevent cyber assaults.

  • Demonstrating Cybercriminal Techniques

These demonstrations show CEOs the hacking tactics that malicious hackers may employ to breach their networks and breach the data security of their companies. Companies that have a detailed understanding of the tactics used by attackers to breach their systems are better prepared to avoid such invasions.

  • Assisting in the Preparation for a Cyber Assault

Ethical hackers comprehend how malicious hackers work and how they will use new knowledge and ways to attack systems. Security experts who collaborate with ethical hackers are adequately prepared to plan for future attacks because they can respond more quickly to the ever-changing dynamics of cybersecurity threats.

All these skills and extensive knowledge of cybersecurity isare a necessary requirement forto becominge an ethical hacker. You can learn these skills in a CEH course and advance your career in cybersecurity. 

The Role of an Ethical Hacker

An ethical hacker is responsible for various aspects. An ethical hacker’s typical job responsibilities include:

  • To write scripts for penetration testing and vulnerability assessments to test system and network risks
  • To deal with internet fraud on both a corporate and individual level
  • To prevent network snooping, broken wireless encryption, and hijacked web apps and servers
  • Invade intrusion detection and prevention systems, and firewalls to guarantee that no malicious activity occurs
  • To keep susceptible data under control and to repair any incursions
  • To provide low-level tools for better security monitoring and evaluation
  • To develop thorough reports on the most critical security discoveries and distribute them to cross-functional departments
  • To conduct risk assessments on all hardware and software systems in the company’s network
  • Formulate and execute digital security rules and best practices

What Distinguishes Ethical Hackers from Malicious Hackers?

Ethical hackers are professionals who utilize their hacking abilities for the betterment of an organization, like assisting organizations in improving their cybersecurity infrastructure. Malicious hackers, on the other hand, employ their abilities for illegal or disruptive reasons.

Motivation is a crucial difference between ethical and malicious hackers. Ethical hackers are driven by a desire to improve security. Malicious hackers, on the contrary, are driven by a desire for personal gain or to inflict harm.

Another notable difference is that ethical hackers usually have the authorization to get into systems, whereas malevolent hackers do not. This authorization is frequently granted in the form of an agreement or a contract between the ethical hacker and the business with whom they are dealing.

While ethical hackers and malevolent hackers share similar characteristics, the variations in goal and authorization make them two separate and distinct sorts of hackers. Ethical hackers are critical to the security of our systems and data, but malevolent hackers pose a major threat to both individual users and companies.

Ethical Hacking Techniques

Ethical hacking methods are used to assess the system’s security and networks. Ethical hackers can assist businesses in identifying and mitigating problems by imitating real-world assaults. Some of the common techniques are denial of service attacks, social engineering, SQL injection, and password cracking. 

The process of password cracking is deciphering passwords with specialized software, which frequently uses a library of common terms or variants thereof. Social engineering works by duping people into revealing confidential information like passwords or credit card details. Denial of service attacks flood systems with requests, making genuine users unable to access them. SQL injection adds malicious scripts into web forms to get access to databases holding confidential details.


As the world’s dependence on technology rises, so does the demand for ethical hackers. Ethical hackers are accountable for testing systems and detecting issues before criminal entities can exploit them. Ethical hackers can explore a diverse range of job prospects. Some operate as independent experts, while others work for big corporations or government agencies. 

In the coming years, the need for ethical hackers is likely to increase. This is because cyber vulnerabilities are always growing, and businesses must secure their infrastructure from attacks.

If you want to learn more about becoming a certified professional ethical hacker, explore the CEH course, which includes instructor-led live training and real-world project experience. This training will help you get a thorough understanding of cybersecurity and proficiency in the domain.


Q1: Is ethical hacking a solid career path?

Yes, if you are passionate about ethical hacking and cybersecurity, it is a wonderful job, but it requires a comprehensive grasp of all aspects of the IT domain.

Q2: Who should pursue a profession in ethical hacking?

A candidate must understand systems, wireless, and wired networks to become an ethical hacker. They must be comfortable with operating systems, especially Linux and Windows. They must understand firewalls, networks and file systems.

Q3: Is ethical hacking legal?

Yes, it is legal as long as it is done with the owner’s consent to identify faults in the system and give solutions. It also protects the system from further harm caused by the hackers.
