A digital forensics chain-of-custody form is a document that provides a clear and complete record of the sequence of events that occurs from the time a digital artifact is collected until it is analyzed and used as evidence. The form should include the date and time when the artifact was collected, so that the exact time it was obtained can be determined. Additionally, the form should include information about the provenance of the artifact, such as its origin and any steps that have been taken to maintain its integrity. The order of volatility, a CRC32 checksum, the vendor's name, and a warning banner are not essential components of a digital forensics chain-of-custody form.
