Having a good grasp of Linux is essential to your success as a cybersecurity expert, and in the IT industry in general. Linux dominates all areas of computing besides Desktop (user-facing) use and here are some numbers to keep it brief (source):
Linux serves as the foundation for a wide array of operating systems, from servers, to cars, to smart home speakers, to smartphones. Learning Linux provides you with the ability to work across diverse platforms and systems.
Proficiency in Linux is often a requirement for various IT and tech roles, such as system administrators, DevOps engineers, network administrators, and software developers. Acquiring Linux skills can enhance your competitiveness in the job market.
Linux is built on open source principles, allowing anyone to access, modify, and distribute its source code. Learning Linux introduces you to the collaborative nature of open source software development.
Linux emphasizes the use of the command-line interface (CLI) for system management and tasks. Developing command-line skills boosts efficiency and provides deeper insights into the operating system's functioning.
Linux is renowned for its strong security features. Learning Linux exposes you to security practices like user permissions, encryption, firewalls, and more, essential in today's cybersecurity landscape.
Linux offers extensive customization options, enabling tailoring of the system to specific needs. This level of control is valuable for personal use and managing complex server environments.
