The Importance Of Computer Forensic Analysis

The specificity of a computer forensic analysis depends on the domain or field of the criminal investigation. Thus, the procedure of forensic analysis will differ for homicide and corporate data theft and it is very clear why. There are common features shared as part of the legal system, or some form of common grounds. First of all, it is not enough to just find evidence that is acceptable in the court of law. Sometimes the nature of the evidence is versatile or perishable and the computer forensics investigator has to do everything to preserve it or at least to make good viable copies. Furthermore, the forensic analysis actually starts when the crime scene has been thoroughly searched by the forensic experts.

Traces and evidence cannot be identified on site, it takes professional computer forensic analysis to find relevant details and establish facts. Thus, fingerprint matching, facial portraits from DNA prints, analysis of minerals, textiles, germs and bacteria as well as other elements collected on the crime scene get under micro-scrutiny to be proved or improved as relevant or irrelevant for criminal justice. Medical exams are also commonly necessary when there are victims involved in a certain crime; medical experts will perform such forensic analysis, giving the answer to the legal questions.

It is the popular belief that a forensic analysis necessarily involves manslaughter or other very tragic crime but forensic analysis serves for a very large number of investigations. Where there is a a case of financial fraud, a work accident, a corporate data theft, a fire and so on, a good forensic analysis could reveal the culprit, and even help to reducing loss and recovering data. We tend to attribute a criminal justice picture to forensic analysis but this is the model we’ve grown used from TV series such as CSI: Crime Scene Investigation; yet reality could be very different from that.

Moreover, information on how a computer forensic investigation is conducted is plentiful in Discovery documentaries in the forensic crime investigations. It seems like there is an international trend to be fascinated with the sensationalism of violence and ever younger people are psychologically affected by such trends in the group subconscious. Nobody should interfere with forensic investigation because without knowing it one could destroy or ruin evidence and affect the very course of a trial. Let’s leave the drama aside and allow the professionals to do their jobs. A forensic analysis is not amateur detective work but something a lot more complex from the scientific point of view.
