Simple Explanation – Cyber Security ≠ Info Security ≠ IT Security

Information Security, IT security and Cyber Security

In an increasingly digitized world where data has become one of the most valuable assets, ensuring the security of information is paramount. But what exactly do terms like information security, IT security, and cyber security mean? Are they interchangeable, or are there clear differences between them? In this post, we aim to clarify these questions and shed light on the relationship between these concepts.

What is Information Security?

Information security refers to the comprehensive protection of information from unauthorized access, use, disclosure, destruction, alteration, or theft. It encompasses not only the technological aspects of security but also the processes, policies, and procedures employed to safeguard information. Information security is a holistic approach aimed at ensuring the confidentiality, integrity, and availability of information.

What Does IT Security Mean?

IT security specifically focuses on protecting information technology (IT) systems, networks, and infrastructures from threats such as malware, hacker attacks, and data breaches. IT security deals with the technological measures and solutions for defending against cyberattacks and securing IT resources. It is a subset of information security and plays a crucial role in ensuring the security of data and systems.

The Significance of Cyber Security

While often used interchangeably with IT security, the term cyber security specifically refers to protecting computer systems, networks, data, and programs from cyber threats. Cyber security encompasses not only technological aspects but also the analysis of cyber risks, the development of defense strategies, and the response to security incidents. It is closely linked to the security of information and IT systems and is essential for combating cyber threats effectively.

Overlap and Interconnections

Although information security, IT security, and cybersecurity have different focuses, there are many overlaps between them. Many security measures implemented in IT security are part of a broader framework for ensuring information security. Similarly, many of the threats addressed by cyber security are closely related to the security of information and IT systems. A holistic approach that considers these aspects is crucial for effectively securing data and systems.


Information security, IT security, and cybersecurity are closely interconnected concepts, all aimed at ensuring the security of information and IT systems. While information security represents a comprehensive approach that includes technological aspects as well as processes and policies, IT security and cyber security specifically focus on protecting IT resources and defending against cyber threats. In addressing the challenges of today’s cyber threats, businesses, organizations, and governments must adopt holistic approaches that integrate information security, IT security, and cyber security to effectively protect their data and systems.
