In the world of digital forensics, a specialized discipline that deals with the recovery, investigation, and analysis of digital devices and digital materials, there’s a fundamental principle that guides every action: the first rule of digital forensics, which is to ensure the original evidence remains unaltered.
Why is this so critical? Digital evidence, like any form of evidence, must maintain its integrity to be considered reliable and legally admissible in court. Any alteration to the original data, intentional or not, could compromise the validity and potentially affect the outcome of investigations and legal proceedings.
This cardinal rule takes life in the practice of creating a forensic copy or image of the digital evidence as the first step in the process. Investigators work on this copy, leaving the original data completely untouched. This way, if there’s any question about the handling or analysis of the evidence, investigators can go back to the original source, and verify the accuracy of the copied data.
Once the forensic copy is made, the subsequent analysis involves a series of steps. These steps often include:
But no matter the complexities of the subsequent steps, everything in digital forensics circles back to the first rule: the original evidence must remain unaltered. It’s the bedrock principle that upholds the integrity of digital evidence, ensuring its credibility and trustworthiness.
