Every organisation relies on technology to operate, but with that reliance comes risk. Cyberattacks, ranging from ransomware to data breaches, are increasing in frequency and sophistication, making cybersecurity expertise more crucial than ever. 

Before exploring advanced security tools or strategies, professionals need a solid foundation in IT fundamentals. Understanding how systems, networks, and software work is the first step in effectively protecting digital assets.

IT fundamentals encompass the essentials, including computer hardware, operating systems, software applications, networking concepts, and basic security principles. 

Mastering these areas enables cybersecurity professionals to identify vulnerabilities, troubleshoot issues, and implement preventive measures with confidence. It also sets the stage for using security tools effectively in real-world scenarios, from monitoring networks to analysing threats.

Structured training, such as a cybersecurity analyst course, combines theoretical knowledge with hands-on experience, helping learners bridge the gap between understanding IT basics and applying them in practical, high-stakes environments. 

This article explores the key IT fundamentals every cybersecurity professional should know, why they matter, and how to develop them for a strong, career-ready skill set.
