After that, you’ll concentrate on fundamental hacking ideas like security and anonymity while developing your bash and Python scripting skills.As you learn how to cover your tracks by altering your network information and fiddling with the rsyslog logging utility, and also how to write a tool to scan for network connections as well as connect to and listen to wireless networks, practical tutorials as well as exercises will strengthen as well as test your skills. You’ll pick up Linux Basics for Hackers rapidly. Getting a copy of this book might be one of the best things you can do to improve your cybersecurity skills, whether you’re just starting out or working your way up to expert level.

Why Linux is Important for Hackers:

Due to the Linux kernel’s effectiveness and portability, embedded systems are increasingly depending on it as technology develops. People are embracing the Internet of Things since more and more devices are being connected to the internet every day. These devices depend on Linux and must have internet security. Using scripting languages like BASH or even Python, Linux enables us to swiftly and simply implement certain OS features. Because we have access to Linux’s whole source code, we can comprehend how it functions. Every part of the operating system’s operation can be changed. Operating systems like Windows do not permit for such things. One of the reasons security aficionados prefer Linux to Windows is the freedom to modify the source code as you see fit. Most tools used for hacking are created for Linux. Over 90% of the accessible hacking tools today were created for Linux. Given that Kali Linux is the most widely used hacking OS, we have concentrated on it. Due to its dependability and the abundance of internet resources that make it simple for you to learn how to use it in your quest to become an ethical hacker, we recommend it.
