WAN Expert Witnesses & Computer Forensics

Wide Area Network (WAN) expert witnesses may opine on computer networks, routing, WAN, and related topics. Here, The Digital Forensic Group answers the question What is Computer Forensics?

Computer forensics, also known as digital forensics, is the practice of identifying, collecting, preserving and analyzing legal evidence from digital media such as computer hard disk drives. Since digital evidence is both fragile and volatile, it requires the attention of a certified specialist to ensure that materials of evidentiary value are effectively isolated and extracted in a scientific manner to withstand the scrutiny of the legal system. The goal of computer forensics is to explain the current state of a digital artifact. These can include a computer system, storage medium (such as a hard disk or CD-ROM), an electronic document (e.g. an email message or JPEG image) or even a sequence of packets moving over a computer network.
