What is a primary function of digital forensics tools in the evidence collection process?

One of the primary functions of digital forensics tools is to document the chain of custody. The chain of custody refers to the process of maintaining and documenting the handling of evidence to ensure its integrity and authenticity throughout an investigation. Digital forensics tools play a crucial role in this process by automatically logging and recording every action taken on the evidence, including details about who accessed it, when it was accessed, and what modifications were made, if any. This meticulous documentation is vital for maintaining the credibility of the evidence in legal proceedings, as it helps to prove that the evidence has not been altered or tampered with from the point of collection to its presentation in court. Therefore, the ability to document the chain of custody is essential to uphold the integrity of the forensic investigation and support the validity of the findings.
