Digital Forensics: How does it Work and why is it Significant Today?

Enterprise Security Magazine | Friday, November 30, 2018

Digital forensics is a branch of science that focuses on recovery and investigation of artefacts found on digital devices. It can be seen mostly in popular television shows like Crime Thriller and in movies, where it is used by a team of investigators to find out stolen sensitive information.

Stereotypically, most people co-relate digital forensics with employee theft. An article published recently by Dark Reading highlights the necessity of digital forensics in a world where 69 percent of business enterprises felt that there has been a corruption of data by insiders in last one year. Adding to the woes, almost one-third of organizations are unable to prevent such kind of insider attacks. However, digital forensics not only battles theft and fraudulent cases but is also used in copyright infringements or patents, employment and commercial disputes, domestic matters, and incident responses on breaching of data.

Digital forensics has touched the public, thanks to shows like CSI (Crime Scene Investigation). However, what is shown on television is not the actual way investigation is carried out. In real, the investigation process is complicated, and a thorough process is required. The initial stage involves forensic readiness while examining where the investigation is carried out to review existing electronically-stored information (ESI) data maps and locations storing sensitive data.

The next two steps involve the collection and identification of data and its processing and analysis. Once the integration of data to be analyzed is verified by examiners, a plan is made to extract data, and identify potential ESI sources. The investigation determines the extracted items because of its relevance to the forensics request. The non-extracted items are simply processed. Next, when the processing begins, examiners connect all the dots to form a complete picture of all potentially threatening actions identified during investigation. The analysis accurately made, thoroughly checked, and recorded to provide the required documentation for courts or legal entities.

In the final stage, the examiner produces a structured report based on his or her research. This report also includes recommendations on how to lift up their incident response plans and make it a proactive incident response program in order to avoid future attacks.
