The rapid expansion of the use of digital technology has been followed by a similar increase in computer-based crime. This increase in criminal activity has led to a demand for qualified computer forensic analysts who can investigate digital technology based crime and uncover evidence that helps build a case against suspects. Forensic computer analysts may be involved in a range of investigations, such as online fraud, digital espionage, counter-terrorism, possession of illegal imagery and information theft.
A typical investigation would involve identifying and securing computer equipment, followed by the application of forensic methods and specialist computer programmes in pursuit of evidence. Tasks include recovering data from digital media, analysis of records to establish the location of a device, uncovering data trails, careful documentation of the investigation, presenting findings and acting as an expert witness in court.
