When a security analyst captures forensic evidence from a potentially compromised system, it is important to ensure that the evidence is handled in a way that preserves its integrity and admissibility in a court of law. To do this, the chain of custody must be maintained.
The chain of custody is the documentation of the custody, control, transfer, analysis, and disposition of physical and electronic evidence. It is essential to maintain the chain of custody to establish the authenticity and reliability of the evidence.
Maintaining the chain of custody involves several steps, including documenting the time and date of evidence collection, identifying who collected the evidence, labeling the evidence, and securely storing the evidence in a tamper-evident container.
Preserving the data is also important to ensure that the evidence is not altered or destroyed. This involves making a bit-for-bit copy of the original data and working with the copy instead of the original.
Obtaining a legal hold may be necessary in some situations to prevent the destruction of evidence. A legal hold is a directive to preserve all relevant information, including electronically stored information, for a pending or anticipated legal proceeding.
Recovering data at a later time may also be necessary in some situations, but it is not the primary concern when capturing forensic evidence. The primary concern is maintaining the chain of custody to ensure that the evidence is admissible in court.
