Explanation
Chain of custody is a process that documents how evidence is collected, handled, stored and transferred during a cybercrime investigation. It ensures that the evidence is authentic, reliable and admissible in court. If the chain of custody is violated during an investigation, it can compromise the integrity of the evidence and lead to the case being dismissed. Open-source software, EULA (end-user license agreement) and AUP (acceptable use policy) are not related to cybercrime investigations or evidence handling. Verified References:
