What is a live USB?

A live USB is a USB drive that contains a bootable operating system that can be run directly from the device, without affecting the host system's hard drive or installed OS. It is similar to a live CD or DVD, but with the advantage of being faster, more portable, and more customizable. A live USB can be used for various purposes, such as testing a new OS, troubleshooting a system, performing data recovery, or conducting security audits.

Why use a live USB?

There are many reasons why you might want to use a live USB instead of installing an OS on your hard drive or virtual machine. Some of them are:

• It's non-destructive - it makes no changes to the host system's hard drive or installed OS, and to go back to normal operations, you simply remove the Kali live USB drive and restart the system.

• It's convenient - you can carry your OS with you wherever you go, and use it on any compatible computer. You can also store your personal files and settings on the same USB drive or on another partition.

• It's secure - you can run Kali Linux in an isolated environment, without leaving any traces on the host system. You can also encrypt your data on the USB drive for extra protection.

• It's flexible - you can customize your Kali Linux installation with different tools, packages, themes, and configurations. You can also update or upgrade your Kali Linux system without affecting the host system or the USB drive.

As you can see, using a live USB has many benefits, especially for security enthusiasts and professionals who want to use Kali Linux on different machines and scenarios. However, before you can create and use a Kali live USB, you need to meet some requirements.

Requirements for Creating a Kali Live USB

To create a Kali live USB, you will need the following:

• A USB drive with at least 8 GB of space - this is the minimum recommended size for a Kali live USB, as it will allow you to store the Kali Linux system, your personal files, and some extra space for updates and upgrades. You can use a larger USB drive if you want more space or if you want to create multiple partitions on it.

• A computer with internet access - you will need a computer that can connect to the internet to download the Kali Linux ISO file and the tool for creating bootable USB drives. You can use any OS on your computer, such as Windows, Linux, or macOS.

• A tool for creating bootable USB drives - you will need a software that can write the Kali Linux ISO file to your USB drive and make it bootable. There are many tools available for this purpose, but in this article, we will focus on two of them: Rufus and UNetbootin. Rufus is recommended for Windows users, while UNetbootin is compatible with Windows, Linux, and macOS.

Once you have these requirements ready, you can proceed to the next step: downloading the Kali Linux ISO file.
