Which type of evidence is most reliable in a forensic investigation?

Digital logs from servers are considered the most reliable type of evidence in a forensic investigation due to their ability to provide objective, consistent, and time-stamped records of activity. These logs are often generated automatically by servers and can include detailed information about user access, system events, and transaction history. Their authenticity is typically easier to verify through metadata, making them less susceptible to manipulation compared to other forms of evidence.

In contrast, testimonies from witnesses can be influenced by personal biases, memory inaccuracies, and subjective interpretations, which makes them less reliable. Emails can be altered or fabricated, and while they can support a case, their authenticity must be established through verification methods. Social media posts can also be manipulated or taken out of context, leading to potential misinterpretations. Therefore, digital logs stand out as a more objective and reliable source of evidence in forensic investigations.
