There are many situations or scenarios where you may need to use the Linux system on your computer, such as no boot, or problems because of viruses or otherwise.
Of course, everyone knows the Ubuntu distribution, which provides you with the advantage of running the system from memory without sparing on your computer, but of course does not provide you with many tools that you may need as a professional, so I propose today another distribution similar and built on the Ubuntu with hundreds of ready-made tools called CAINE 9
CAINE 9 is a GNU / Linux distribution based on the Ubuntu distribution. It was created as a digital criminal investigation project. Currently the project manager is Nani Basiti from Italy. This distribution provides you with a complete environment with a set of tools and software to help you with your work. It also has a clear and easy graphical destination.
You can take it on any flash drive and leave it without the need to install it on your device, which provides you with great flexibility to do a digital analysis on any computer and solve problems through the tools provided by the system. Also nice in this distribution is that it has many tools for Windows also and when you take advantage of it you can mount Lai HardSec and protect it from modification without the need for HardWare.
