Digital Forensics with Kali Linux - Second Edition

By: Shiva V. N. Parasram

Overview of this book

Kali Linux is a Linux-based distribution that's widely used for penetration testing and digital forensics. It has a wide range of tools to help for digital forensics investigations and incident response mechanisms. This updated second edition of Digital Forensics with Kali Linux covers the latest version of Kali Linux and The Sleuth Kit. You'll get to grips with modern techniques for analysis, extraction, and reporting using advanced tools such as FTK Imager, hex editor, and Axiom. Updated to cover digital forensics basics and advancements in the world of modern forensics, this book will also delve into the domain of operating systems. Progressing through the chapters, you'll explore various formats for file storage, including secret hiding places unseen by the end user or even the operating system. The book will also show you how to create forensic images of data and maintain integrity using hashing tools. Finally, you'll cover advanced topics such as autopsies and acquiring investigation data from networks, operating system memory, and quantum cryptography. By the end of this book, you'll have gained hands-on experience of implementing all the pillars of digital forensics: acquisition, extraction, analysis, and presentation, all using Kali Linux tools.

Data volatility

In this section, we will take a look at why data is lost when power to the volatile memory is lost.

Data can exist as long as the media it is stored on is capable of storing the data. Hard drives (mechanical and solid-state), flash drives, and memory cards are all non-volatile storage media. Although SSDs have made, and continue to make, drastic improvements in data access times, RAM thus far remains the faster type of memory, typically referred to only as memory, inside devices.

RAM, however, is volatile memory. Unlike non-volatile memory found in hard drives and flash drives, data stored in RAM is kept there temporarily, only for as long as there is an electrical current being provided to the chips. There are two types of RAM that we need to be aware of: Static RAM (SRAM) and Dynamic RAM (DRAM).

SRAM is superior to DRAM but is far more costly because of the expensive materials used in building the chips. SRAM is also physically much larger than DRAM. SRAM...
