So you want to be a forensic analyst?
Forensic analysis of computers is a discipline growing in popularity amongst both the forensic science and computer security fields. Several university courses now teach the basics and professional qualifications are on offer from the forensic software developers. Although the cost of entry into the field can sometimes be prohibitive the market for forensic analysts is still strong, and as time goes by the free software available to hobbyists is becoming more advanced.
Becoming an analyst probably, still, does not require a formal degree in the field. Most of the skills can be learned through training and simple experience. Being an analyst requires two main skillsets:
- Attention to detail
- Often investigations culminate in legal proceedings, either of the civil or criminal nature. To satisfy the, reasonably strict, rules of courts around the world digital evidence needs to be audited and carefully tracked. As detailed later in the book, digital media is easily altered and courts are still resisting evidence without a full audit log.
- Unlike other areas of forensic science, digital investigations tend to be much more free form. They often require investigators to have a deep grounding in both the technical aspects of computers and the psychology of the computer criminal. Much of the latter is learned over time and practice.
