What is Hacking?

Welcome to our “Definitions” category, where we dive into various concepts and provide clear explanations to help you understand them better. Today, we are going to demystify the term “hacking” and shed some light on what it truly means.

Understanding Hacking

Hacking is often portrayed in movies and popular culture as a mysterious and clandestine activity. However, in reality, hacking is simply the act of gaining unauthorized access to computer systems, networks, or devices with the intention of exploring, manipulating, or potentially exploiting their inner workings. It encompasses a wide range of activities that can be classified into different categories, such as ethical hacking (also known as penetration testing) and malicious hacking.

Key Takeaways:

  • Hacking involves unauthorized access to computer systems, networks, or devices.
  • It can be categorized as ethical hacking (penetration testing) or malicious hacking.

Types of Hacking

Hacking can be broadly classified into two main types: ethical hacking and malicious hacking.

Ethical Hacking

Ethical hacking, also known as penetration testing, is a legitimate practice where certified professionals are hired to identify vulnerabilities in computer systems and networks. Their aim is to assess the security infrastructure, locate weak points, and recommend improvements to prevent unauthorized access. Ethical hackers use their knowledge and expertise to safeguard organizations from potential threats by proactively identifying and patching vulnerabilities before malicious hackers exploit them.

Malicious Hacking

Malicious hacking refers to the act of gaining unauthorized access to computer systems or networks with ill intentions. Malicious hackers are commonly referred to as “black hat” hackers and their activities can cause severe damage, such as data breaches, financial losses, identity theft, and even disruption of critical infrastructure. Their motives might include personal gain, revenge, or simply causing chaos. It’s important to note that malicious hacking is illegal and punishable by law.

Protecting Against Hacking

To protect your computer systems, networks, and personal devices against hacking attempts, it’s essential to follow best cybersecurity practices. Here are a few key tips:

  • Use strong and unique passwords: Avoid using common passwords and consider using password managers to keep track of multiple complex passwords.
  • Keep software and systems up to date: Regularly update your operating systems, applications, and security software to patch vulnerabilities and stay protected against emerging threats.
  • Install a robust firewall: A firewall acts as a barrier between your network and potential threats, blocking unauthorized access attempts.
  • Be cautious of phishing attempts: Be wary of unsolicited emails, messages, or phone calls asking for sensitive information. Validate the source before sharing any personal details.
  • Enable two-factor authentication (2FA): Adding an extra layer of security to your accounts by enabling 2FA can significantly reduce the risk of unauthorized access.


In summary, hacking involves gaining unauthorized access to computer systems, networks, or devices. It can be categorized as ethical hacking (penetration testing) or malicious hacking. Ethical hacking helps organizations identify and fix vulnerabilities, whereas malicious hacking aims to exploit weaknesses for personal gain or harm. To protect yourself from hacking attempts, follow best cybersecurity practices, such as using strong passwords, keeping software up to date, and being cautious of phishing attempts.
