Explanation
Chain of custody is a process that helps ensure that a piece of evidence extracted from a PC is admissible in a court of law. Chain of custody refers to the documentation and tracking of who handled, accessed, modified, or transferred the evidence, when, where, why, and how. Chain of custody can help establish the authenticity, integrity, and reliability of the evidence, as well as prevent tampering, alteration, or loss of the evidence. Data integrity form, valid operating system license, and documentation of an incident are not processes that can ensure that a piece of evidence extracted from a PC is admissible in a court of law.
