The evidence collected during a digital forensic investigation would not be admissible in court if the logs failed to identify the person handling the evidence. This would violate the chain of custody principle, which requires that the evidence be properly documented, secured, and tracked throughout the investigation process.
The chain of custody ensures that the evidence is authentic, reliable, and trustworthy, and that it has not been tampered with or altered. The person who collected the evidence, whether qualified or not, is not relevant to the admissibility of the evidence, as long as they followed the proper procedures and protocols. The evidence collected by the internal forensics team can be admissible in court, as long as they are independent, objective, and competent. The evidence does not need to be fully backed up using a cloud-based solution prior to the trial, as long as it is preserved and protected from damage or loss.
