Digital Forensics with Kali Linux

Overview of this book

Kali Linux is a Linux-based distribution used mainly for penetration testing and digital forensics. It has a wide range of tools to help in forensics investigations and incident response mechanisms. You will start by understanding the fundamentals of digital forensics and setting up your Kali Linux environment to perform different investigation practices. The book will delve into the realm of operating systems and the various formats for file storage, including secret hiding places unseen by the end user or even the operating system. The book will also teach you to create forensic images of data and maintain integrity using hashing tools. Next, you will also master some advanced topics such as autopsies and acquiring investigation data from the network, operating system memory, and so on. The book introduces you to powerful tools that will take your forensic abilities and investigations to a professional level, catering for all aspects of full digital forensic investigations from hashing to reporting. By the end of this book, you will have had hands-on experience in implementing all the pillars of digital forensics—acquisition, extraction, analysis, and presentation using Kali Linux tools.

Revealing Evidence Using DFF

Digital evidence acquisitions and procedures


As we covered in the last chapter, data can be stored on both fixed and removable storage media. Data, however, can easily be deleted or completely lost depending on a multitude of factors that must be considered if we are to ensure the preservation of data. It might even be argued that there are more threats to digital storage than paper-based. The following are some comparisons of threats to both:

  • Threats to paper-based storage include:
    • Water
    • Fire and humidity
    • Bugs
    • Age
    • Natural disasters—floods, earthquakes, tornadoes, hurricanes, and so on
  • Threats to data on storage media include:
    • Human-error and negligence
    • Magnetism and electromagnetic fields
    • Water and condensation
    • Heat
    • Dust
    • Impact
    • Voltage
    • Static electricity
    • Natural disasters—floods, earthquakes, tornadoes, hurricanes, and so on

When exactly does data become evidence? Specific data may have a value that is relative to an investigation when considering the events that transpired.
