Contrasting tampered and untampered disk images

As a cybersecurity professional, you may be given the task of capturing an image of a disk in a forensic manner. Imagine a security incident has occurred on a system and you are required to perform some forensic investigation to determine who and what caused the attack. Additionally, you want to ensure the data that was captured is not tampered with or modified during the creation of a disk image process.

In this section, you will learn how to use various tools on both Microsoft Windows and the Linux operating system to capture a disk image of a local drive and determine whether the image was tampered with or not.
