Combining Kali Linux with a Raspberry Pi – known as Kali Raspberry Pi – creates a powerful and portable tool for cyber security professionals, educators, and hobbyists.

Here, Electronic Specifier takes a look at what Kali Linux and Raspberry Pi are, how they work together, and how to install Kali Linux on a Raspberry Pi.

Kali Linux

Kali Linux is a specialised operating system designed for digital forensics and penetration testing. Developed by Offensive Security, it offers a wide range of tools for security professionals and ethical hackers.

Kali Linux is known for its extensive toolkit, which includes software for network scanning, vulnerability analysis, password cracking, and more. It is a powerful platform for testing the security of networks and systems.

Raspberry Pi

The Raspberry Pi is a small, affordable single-board computer developed by the Raspberry Pi Foundation, and it is widely used for educational purposes, DIY projects, and prototyping.

Despite its small size, the Raspberry Pi is capable of running a variety of operating systems and performing tasks typically handled by a standard computer. Raspberry Pi models vary in specifications, with the most recent versions being more powerful and versatile.

Kali Linux on Raspberry Pi

Kali Linux can be installed on a Raspberry Pi, effectively turning the device into a portable, low-cost security testing tool. This combination allows security professionals to carry out penetration tests in a mobile and cost-effective way.

Compatibility

Kali Linux is compatible with the following versions of Raspberry Pi:

  • Raspberry Pi 2
  • Raspberry Pi 3
  • Raspberry Pi 4
  • Raspberry Pi 400

The latest versions of Raspberry Pi, including the Raspberry Pi 4, are recommended for the best performance due to their enhanced processing power and RAM.

The versatility of Kali Raspberry Pi

Kali Linux on Raspberry Pi is a versatile tool that can be used in a variety of scenarios.

For penetration testing, it allows security professionals to assess the vulnerabilities of networks and systems. The portability of Raspberry Pi makes it convenient for on-site testing, allowing assessments to be carried out in different environments without needing a bulky setup.

In network monitoring, Kali Raspberry Pi can be used to capture and analyse network traffic using tools like Wireshark. This is particularly useful in identifying potential security threats or performance issues within a network.

For those learning about ethical hacking and cyber security, Kali Raspberry Pi is as an accessible platform to practice and develop skills. The low cost and ease of setup make it ideal for students and educators alike.

In IoT security testing, Kali Raspberry Pi can be used to evaluate the security of IoT devices. Its small size and portability allow for testing in various settings, ensuring that IoT devices are secure before deployment.

Finally, Kali Raspberry Pi can be used to create a portable lab environment. This is particularly useful for demonstrations, workshops, or even fieldwork, where a full-sized lab setup would be impractical.

Installation process

To install Kali Linux on a Raspberry Pi, follow these steps:

  • Download Kali Linux ARM image: Visit the official Kali Linux website and download the appropriate ARM image for your Raspberry Pi model.
  • Prepare the microSD card: Use a tool like Balena Etcher to flash the downloaded image onto a microSD card (minimum 16GB recommended).
  • Insert the microSD card into Raspberry Pi: Place the prepared microSD card into your Raspberry Pi's card slot.
  • Connect peripherals and power up: Attach a keyboard, mouse, monitor, and power supply to your Raspberry Pi.
  • Initial boot and configuration: Power on the Raspberry Pi. The system will boot into Kali Linux, where you can configure your settings.
  • Update and upgrade: After the initial setup, open a terminal and run sudo apt update followed by sudo apt upgrade to ensure all packages are up to date.

This combination of Kali Raspberry Pi offers a powerful, portable solution for cyber security professionals, educators, and enthusiasts, making it a versatile tool in the field of information security.
