Why is it important to maintain the integrity of original data?

Maintaining the integrity of original data is critical in digital forensics primarily because it ensures that the evidence collected and analyzed is credible. When forensic analysts work with digital evidence, they must establish that the data has not been altered or tampered with since it was collected. This is essential not only for the investigation's validity but also for any potential legal proceedings that may arise from the findings.

If the integrity of the data is compromised, it can lead to challenges regarding its reliability, potentially undermining the entire forensic process. This can affect the outcomes of criminal cases, civil litigation, or any scenario where the data is used as evidence. Therefore, maintaining unaltered copies of the original data and properly documenting the chain of custody serves to uphold the integrity and trustworthiness of the digital evidence in question.
