Computer forensics is a branch of digital forensic science that is concerned with evidence found in computers and other digital storage media. This field is also referred to using the term computer forensic science. The goal of this field of study is examining digital media forensically with the intention to identify, preserve, recover, analyze, and present opinions and facts concerning digital information therein. The professional who does this job is called a computer forensic expert.
The field of digital forensic science is a relatively new one with a short history. The creation and development of this profession became necessary in the early 1980s following the increased availability of personal computers to members of the public. With the increase came a number of computer crimes as people used the help of computers to commit crime. Thus, computer-aided crime became an issue and has continued to cause mayhem, being termed as cyber crime today.
It became necessary to have people trained in techniques of recovering and investigating digital evidence to use in courts when computer-aided crimes rose. The application of the field has now expanded and is used to investigate rape, espionage, child pornography, cyberstalking, and fraud among other crimes. It also became a method of information gathering in legal proceedings.
The scope of digital forensic is very wide. It goes beyond simple retrieval of information to reconstruction of events. The application of this field in legal proceedings is guided by very strict and rigid rules. This is often contrasted from the flexibility found within the civilian domain. This science has been used in many high-profile cases and continues to become an accepted and reliable source of evidence in European and US courts.
Forensic science professionals have numerous duties and responsibilities. Examples of their responsibilities include investigating security incidents and data breaches, recovering and analyzing data from computing equipment, and dismantling and reconstructing damaged digital systems. They do not work with data and devices alone. They write technical reports, give counsel regarding legitimacy of evidence, and prepare evidence used in courts.
These professionals also provide expert testimonies for court proceedings and train officers of law enforcement about procedures used in digital evidence. They remain relevant in the profession by keeping abreast with emerging software, methodologies, and technologies. This requires them to read and research on new technologies and those that are getting retired.
Having reverse engineering skills is vital in this field. One must be able to think like a criminal backwards. There are many employers for professional of forensic science. Some of them include law enforcement, private consulting firms, legal firms, federal, state, and local governments, and large corporations.
Surviving in the job requires one to have good oral and writing skills. One must be able to effectively communicate the evidence they gather from systems to relevant parties both in writing and in speech. Curiosity and insight are also two very important skills needed.
