Digital forensics (sometimes Digital forensic science) is a branch of forensic science encompassing the recovery and investigation of material found in digital devices, often in relation to computer crime.[1][2] The term digital forensics was originally used as a synonym for computer forensics but has expanded to cover all devices capable of storing digital data and is now used to describe the entire field.[1] The discipline evolved in a haphazard manner during the 1990s and it was not until the early 2000s that national policies were created. Investigations can fall into four categories. The most common category is forensic analysis, where evidence is recovered to support or oppose a hypothesis before a criminal court, this is closely related to intelligence gathering, where material is intended to identify other suspects/crimes. eDiscovery is a form of discovery related to civil litigation and intrusion investigation is a specialist investigation into the nature and extent of an unauthorized network intrusion. The technical side of investigations is divided into several sub-branches; computer forensics, network forensics, database forensics and mobile device forensics. Any number of the fields may be utilised in an investigation. As well as identifying direct evidence of a crime, digital forensics can be used to attribute evidence to specific suspects, confirm alibis or statements, determine intent, identify sources (for example, in copyright cases) or authenticate documents.[3] Investigations are much broader in scope than other areas of forensic analysis (where the usual aim is to provide answers to a series of simpler questions) often involving complex time-lines or hypothesis.[4] The digital forensic process encompasses the seizure, forensic imaging (acquisition) and analysis of digital media. Finally producing a report of the digital evidence for the courts or an employer. Computer devices tend to store large amounts of information in cache/log files and deleted space and forensic examiners can recover this data as part of the analysis process. Contents [hide]

The first computer crimes were recognized in the 1978 Florida Computer Crimes Act, which included legislation against the unauthorized modification or deletion of data on a computer system.[5][6] Over the next few years the range of computer crimes being committed increased, and laws were passed to deal with issues of copyright, privacy/harassment (e.g., cyber bullying, cyber stalking, and online predators) and child pornography.[7][8] It was not until the 1980s that federal laws began to incorporate computer offences. Canada was the first country to pass legislation in 1983.[6] This was followed by the US Federal Computer Fraud and Abuse Act in 1986, Australian amendments to their crimes acts in 1989 and the British Computer Abuse Act in 1990.[6][8] [edit]1980s-1990s: Growth of the field

The growth in computer crime during the 1980s and 1990s caused law enforcement agencies to begin establishing specialized groups, usually at the national level, to handle the technical aspects of investigations. For example, in 1984 the FBI launched a Computer Analysis and Response Team and the following year a computer crime department was set up within the British Metropolitan Police fraud squad. Besides being law enforcement professionals many of the early members of these groups were also computer...
