CompTIA Security+ Question J-37

Which of the following is the MOST important step for preserving evidence during forensic procedures?

A. Involve law enforcement
B. Chain of custody
C. Record the time of the incident
D. Report within one hour of discovery

Answer: B

Chain of custody deals with how evidence is secured, where it is stored, and who has access to it.

When you begin to collect evidence, you must keep track of that evidence at all times and show who has it, who has seen it, and where it has been. The evidence must always be within your custody, or you’re open to dispute about possible evidence tampering. Thus to preserve evidence during a forensic procedure the chain of custody is of utmost importance.
