What should be done first before analyzing digital evidence?

Documenting the evidence is a crucial first step before analyzing digital evidence because it provides a clear and accurate account of the conditions under which the evidence was collected. This documentation includes noting the time and date of acquisition, the method of collection, the chain of custody, and any other relevant details that can affect the integrity and admissibility of the evidence. Proper documentation ensures that there is a reliable record for future reference, which is essential in legal contexts where the authenticity of the evidence may be challenged.

By having thorough documentation, investigators can track how the evidence has been handled, which is vital if the case goes to court. This step lays the foundation for all subsequent actions, as the integrity of the evidence is paramount in any investigation.

Other options focus on important steps as well, but they come after documentation. Backing up data is necessary to preserve the original evidence but should only occur after the initial documentation is complete. Preparing analysis tools is essential for effective analysis but is not a prerequisite for documenting the evidence. Starting the analysis immediately without proper documentation risks compromising the investigation and may lead to issues with data integrity and admissibility later. Therefore, documenting the evidence is the essential first step before any analysis begins.
