An Overview Of Linux In Cybersecurity
By Tom Seest
If you want to pursue a career in cybersecurity, learning about Linux might be beneficial. This operating system has become increasingly popular among businesses, and having knowledge of it will allow you to better protect your network and data.
Regular expressions are a powerful Linux cybersecurity tool, allowing you to rapidly search configuration and log files for pattern-matching vulnerabilities. For instance, regex can identify whether a file contains malicious software or has login credentials for a server.

Linux is an open-source operating system designed for various computer architectures, such as mobile phones, tablets, laptops, and supercomputers. It relies on the kernel – an essential component of an OS – and contains tools, applications, and services packaged together into Linux distributions.
Linux distributions are composed of open-source components that form the software system, with most primary source code licensed under the GNU General Public License (GPL). They may also include additional files such as libraries and other programs.
The GPL mandates that anything created with its code be distributed free of charge, preventing developers from profiting unfairly. This is one major advantage of open-source development and why so many people turn to Linux for their computing needs.
Linux’s popularity in cybersecurity stems from its high flexibility and customizability. Compatible with almost all hardware and software, this makes it suitable for a variety of environments.
For example, a server running Linux can be easily configured for security, performance, reliability, and troubleshooting purposes. Doing so helps businesses avoid costly downtime and prevents vulnerabilities from spreading.
On the market, there is a wide selection of Linux distributions, each offering its own set of features. Some are tailored towards specific users, such as Red Hat Enterprise Linux (RHEL) or CentOS; others focus on cloud or other environments.
Many Linux distributions provide an application store, or central repository, where users can download and install applications. These apps range from basic web browsers to complex database programs. Popular distributions include Ubuntu Linux, Elementary OS, Deepin, and openSUSE.
Linux is an open-source project with an active community of contributors. This group strives to ensure the software remains secure, and they also assist other open-source projects in becoming even more secure.
Linux is not only open-source, but it’s free and user-friendly too. There are thousands of programs available for it that can be tailored to fit any organization’s requirements.

Linux is a widely-used platform in cybersecurity, as it’s available on many security appliances and devices. Furthermore, this open-source operating system doesn’t need expensive licenses to use and promotes innovation within the industry.
Kali Linux, for instance, is a specialized Linux distribution designed to facilitate in-depth penetration testing, vulnerability assessment, and forensic analysis. It’s an invaluable resource for anyone working in security – whether that be their day job or side gig.
It may seem intimidating for those new to Linux, but if you want to take your security career to the next level, investing in CLI shells (command-line interfaces) is an invaluable opportunity to learn about this powerful platform. Additionally, familiarizing yourself with Gnumeric displays and how they can be used for text manipulation will prove beneficial later on down the line.
It’s an ideal time to break into cybersecurity, as demand for skilled professionals and pay rates are both high. If you want to gain entry, a variety of online courses can provide the necessary skillset.
There is a range of free and low-cost resources to explore, such as SANS Cyber Aces. This organization provides online courses that teach the fundamentals of cybersecurity. Furthermore, its website contains certification programs, competitions, and other tools designed to help you kickstart your cybersecurity career.
The great thing about these resources is that they’re free and user-friendly. Many are even mobile-friendly, allowing you to study from your phone or tablet. The key is finding the right resource for you!
Linux offers some truly remarkable tools, one of which is the p0f program. This program can securely identify fingerprints and other sensitive data without interfering with network traffic.

If you need an operating system that’s easy to set up and customize, Linux might be your ideal option. It provides many of the features essential for cybersecurity tasks, plus it’s free. Plus, with Linux, you can install it on as many computers as needed without paying for licenses or software upgrades – making it the ideal choice!
Before anything else, you’ll need to download and install a version of Linux on your computer. There are various distributions available; it’s up to you to determine which one best meets your requirements. Some are more user-friendly than others, so do some research and determine which is ideal for you.
Installation usually takes only a few minutes, though it may take longer, depending on your computer’s speed and memory. Once it’s complete, you should be able to boot from either CD or USB drive and run it directly. Some Linux versions even provide Live distributions so you can install them directly from a CD/USB drive without making any modifications to your hard drive.
Most distributions allow you to set a default hard drive, but if you have multiple drives, creating a partition for the new operating system may be necessary. Although this task may seem complex at first glance, the end result will be worth all the trouble in the end.
Once you’ve created the partition, your computer needs to know what it’s for. Most computers are set to look first for their internal hard drive; however, if you have a USB drive or other external device that should boot from instead, using an interface in BIOS may allow for this change.
Once created, you’ll need to create a username and password for the OS that can be used for administrative tasks. After doing so, access your Linux installation through your computer’s browser or by clicking on the icon on your desktop.
Linux is one of the most widely-used operating systems when it comes to cybersecurity, and it has plenty to offer. Indeed, some of the most effective penetration testing tools are specifically tailored for Linux – such as Kali and Parrot – making it a prime platform for ethical hackers and cybersecurity pros alike.
