Linux offers various tools and methods to identify and mitigate security risks. Some of the useful tools are encryptions, firewalls, and intrusion detection systems.

Furthermore, Linux's command-line interface and shell scripting helps turn it into a solid tool for ethical hacking, managing and automating complex operations and security tasks.

Why do companies use Linux?

Cost-effective: Linux is available to download for free or comes at a lower cost than other copyrighted operating systems. This ease of availability helps make Linux an attractive option for companies on a tight budget.

Open-source: Linux's open-source model allows anyone to use, change and distribute its source code. It helps companies adapt and customise the operating system for their specific needs.

Security: Linux is famous for its features and has built-in firewalls, user control accounts, and file encryption. These features make Linux a popular choice for businesses focusing on data security.

Compatibility: Linux has a growing demand in the market thanks to its compatibility. It allows you to run it on a wide range of hardware and software.

Stability: Linux is globally famous for its stability and reliability in day-to-day tasks. It makes Linux a versatile option for companies that have diverse I.T. environments.

Community support: The Linux community is supportive and active toward learners. The community helps new users find resources to help customise and troubleshoot their problems. It can be an invaluable asset for businesses that rely on the Linux O.S.

Why should you learn how to use Linux?

Linux is safer than the majority of current operating systems because:

Strong Security

There is an abundance of Linux distributions, and new ones are introduced, with some of the most popular being Ubuntu, Debian, and CentOS. 

Due to the regular updates, Linux is considered a moving target, making it difficult for virus creators to target the entire system.

Linux operates under the principle that users have exclusive access to their applications and data. Users can use programs once an administrator installs and configures them.

When you consider how often standalone settings use, Linux is not the most used operating system. Virus creators target operating systems with large user bases because they are easier targets.

Low Cost

Linux provides a significant advantage due to its open-source and available kernel. It is covered by the GNU GPL, which allows for complete customisation per the user's needs. 

Linux comes in various downloadable distributions. Users can download a functional version of the Linux kernel with several add-ons for free. 

But, some distributions, such as Red Hat Enterprise and Ubuntu, offer paid services for add-ons that are not free.

Great Terminal Support

Programmers can connect to backend servers for their projects using add-on software in Linux without installing any specific software. 

The Secure Shell (S.S.H.) tool provides a secure way to access the server. Updating configuration files or hosted Python scripts can be done using editors like Emacs, Nano, and Vim. 

Linux's benefits allow programmers to spend more time building and testing code than struggling with complex workflows.

Great Scalability

Scalability is a must-have feature to meet practical software requirements, and Linux offers it in various ways:

  • Linux is versatile as it supports diverse platforms, making it difficult to find a gadget that it won't work on. It can be scaled to fit any device, from everyday robots to commercial computers.
  • Its small size makes it possible to use on devices with almost any capabilities.
  • Linux is capable of handling heavy loads without getting bogged down.
  • It utilises system resources only when running the program, making it resource-efficient.

Outstanding Server Support

Due to Linux's reputation as a server operating system, programmers often prioritise developing programs that function in a server environment. It implies that Linux-based applications often provide optimal speed, security, and reliability. 

Linux's appeal stems from its low-maintenance nature and ability to remain inconspicuous. As a result, various industries use Linux as a workstation operating system.

The Security Benefits Of Linux For Cybersecurity Professionals

Due to its open-source nature and security capabilities, Linux has become popular as a platform for cybersecurity experts. It is suitable for cybersecurity since it offers an easily-tailored encrypted system for the user's needs. 

Its code is open source, making it one of the most secure operating systems accessible and allowing users to check for flaws and backdoors. 

Cybersecurity professionals utilise Linux to build secure networks and systems. Professionals also use Linux to safeguard their clients' privacy and data. In actuality, it is a valuable tool for individuals in the cybersecurity sector.

Critical Areas of Linux for Cybersecurity Professionals

Linux is a popular operating system for cybersecurity professionals due to its robust security features, versatility, and open-source nature. 

Here are some critical areas of Linux that are essential for cybersecurity professionals:

Command Line Interface (CLI)

Linux uses a command-line interface (CLI) that provides a text-based approach to interfacing with the operating system. 

Cybersecurity experts rely on the CLI to undertake various tasks. Including system administration, network monitoring, and vulnerability scanning. 

Mastering the CLI is crucial for professionals as it empowers them to manage Linux systems with the greatest efficacy.

Security Tools

Linux comes with an extensive suite of security tools invaluable in cybersecurity. Among these tools are intrusion detection systems (I.D.S.), network scanners, vulnerability assessment tools, packet sniffers, and many others. 

It is important for professionals to have a deep understanding of these tools. Knowing how to utilise them to identify and counter potential threats is equally important.

File System Security

Linux offers several tools for fortifying the file system, including file encryption, access control lists (A.C.L.s), and permissions. 

Cybersecurity experts must have the knowledge to leverage these mechanisms in safeguarding confidential data and thwarting any attempts of unauthorised access.

Kernel Security

The foundation of the Linux operating system lies in its kernel. The kernel incorporates an array of security features like access control, memory protection, and process isolation. 

A deep understanding of kernel security is essential for cybersecurity professionals to safeguard the system against attacks that may undermine its integrity.


Linux presents many virtualisation options, including containers and virtual machines. Professionals in the industry use these tools to test software and execute penetration testing. 

A firm grasp on configuring and overseeing virtualised environments is imperative for cybersecurity experts to excel in their roles.


Linux offers scripting languages like Bash and Python that pack a punch in automating tasks. These tools are also useful in system administration, and security tool development. 

Possessing a skillset in scripting is crucial for cybersecurity experts when it comes to using the tools and streamlining repeated tasks.


Linux is essential for cybersecurity professionals due to its open-source nature, security capabilities, and flexibility in customisation. 

Its encrypted system and the ability to tailor it to specific needs make it a valuable tool for ethical hacking and building secure networks and systems. Furthermore, Linux's popularity in cybersecurity makes it a valuable professional skill.
