Computer forensics is an emerging research area that applies computer investigation and analysis techniques to help detection of these crimes and gathering of digital evidence suitable for presentation in courts. This paper provides foundational concept of computer forensics, outlines various principles of computer forensics, discusses the model of computer forensics and presents a proposed model.展开更多
