Admissible evidence: Any evidence that is legally permitted to be used in a court of law. It must be relevant, reliable, and obtained in a manner that follows the rules of evidence. Admissible evidence is typically used in criminal and civil trials to prove the guilt or innocence of a defendant. Examples of admissible evidence include eyewitness testimony, physical evidence, and expert witness testimony. In IT, it must be gathered and preserved following proper digital forensic procedures to maintain its integrity and authenticity. Examples include logs, digital documents, emails, and digital forensics reports.
