What is Cybersecurity? A Beginner’s Overview

Cybersecurity refers to the practice of protecting systems, networks, and data from cyberattacks, unauthorized access, and damage. It involves a combination of technologies, processes, and best practices designed to ensure the confidentiality, integrity, and availability of information.

At its core, cybersecurity focuses on three key principles, often called the CIA Triad:

Confidentiality – Ensuring that sensitive data is accessible only to authorized users
Integrity – Maintaining the accuracy and reliability of data
Availability – Ensuring systems and data are accessible when needed

Cybersecurity covers various domains, including:

Network Security – Protecting computer networks from intrusions
Application Security – Securing software applications
Information Security – Safeguarding data from breaches
Cloud Security – Protecting data stored in cloud environments
Ethical Hacking – Identifying vulnerabilities to improve security

Understanding these fundamentals is the first step toward building a strong foundation in cybersecurity.
