Digital forensics is a branch of forensic science that deals with the analysis and preservation of digital evidence. It involves the collection, examination, analysis, and presentation of digital data in a way that is admissible in a court of law. Digital forensics is used to investigate a wide range of cybercrimes, including computer hacking, online fraud, and child exploitation.

Connect the target USB drive to your Linux forensic workstation through a hardware write-blocker. Identify the disk designation using the terminal: sudo fdisk -l Use code with caution. (Assume the drive is identified as /dev/sdb ) . Generate the initial SHA-256 hash of the evidence drive: sudo sha256sum /dev/sdb > original_hash.txt Use code with caution. Create a bit-stream image using the dd command:

In the world of digital evidence, chain of custody is king, and proper procedure is the difference between catching a cybercriminal and losing a case in court. Digital forensics is a branch of forensic science

The primary objective of a lab manual is to teach investigators how to handle digital evidence without altering it. In legal proceedings, corrupted or improperly handled evidence is inadmissible. Therefore, a lab manual standardizes workflows according to international guidelines, such as ISO/IEC 27037, ensuring that every action taken in the lab is documented, repeatable, and forensically sound. 2.

For educators designing a course, students looking to self-study, or IT managers building an internal training program, finding authoritative manuals is vital.

The chain of custody is the chronological documentation that tracks evidence from seizure to courtroom presentation. It is the single most critical factor for legal admissibility. A broken chain—a missing signature, a gap in timing—can lead to all evidence being ruled inadmissible, potentially dismissing the entire case.
