Forensics: Collection of Sound Digital Evidence

引用

Journal of Information Security 2023年第4期14卷 454-463页

作者： Richard Kabanda Harihar Thapa Luis Rivera College of Engineering University of New Haven West Haven USA

This summary paper will discuss the concept of forensic evidence and evidence collection methods. Emphasis will be placed on the techniques used to collect forensically sound digital evidence for the purpose of introduction to digital forensics. This discussion will thereafter result in identifying and categorizing the different types of digital forensics evidence and a clear procedure for how to collect forensically sound digital evidence. This paper will further discuss the creation of awareness and promote the idea that competent practice of computer forensics collection is important for admissibility in court.
