In today’s digital world, cybersecurity plays a crucial role in protecting information and systems from unauthorized access. In this unit, we will explore the basics of cybersecurity, focusing on how networks operate, the fundamentals of Linux, and how to secure digital environments. You will be introduced to the principles that underpin safe online practices, from understanding how data travels across networks to identifying common vulnerabilities that can be exploited.
We will use the platform TryHackMe to engage in hands-on activities that simulate real-world scenarios. This platform allows you to explore cybersecurity concepts interactively, helping you gain practical skills while learning to think critically about security. In other words, it helps you learn to think like a hacker. While the term “hacking” is often associated with malicious activity, our goal is to focus on ethical practices—learning how to identify and protect against potential threats. By the end of this unit, you will have a better understanding of the importance of cybersecurity and the tools used to maintain it.
