Why do we need an integrated digital forensic laboratory instead of a single forensic tool?

Background

With the continuous development of information technology, we are entering a digital age. Computers, mobile devices, and other related equipment and technologies are increasingly integrated into people’s work and life, enriching and changing people’s lives. However, at the same time, they are also used and applied to criminal activities. Various violations and crimes involving digital material evidence continue to emerge, and digital material evidence has developed into a new form of evidence beyond the traditional, appearing in various cases. Looking to the future, it can be foreseen that with the increasing popularity of digital devices, more and more criminal traces will be left on digital devices used by criminals consciously or unconsciously.

 

To help investigators tackle such issues, the market is full of various single digital forensics tools covering video forensics, database forensics, computer forensics, mobile forensics, etc.

In particular, for mobile forensics, some vendors even split their integrated mobile forensic software into several editions with limited features so as to be able to seek more profits. However, this to some degree weakens their capability of providing integrated digital forensics solutions for users, resulting in the low efficiency and high cost of digital forensics in the global society at this stage.

Therefore, an integrated, process-oriented digital forensics laboratory solution with avant-garde cutting-edge technology is coming into being.

What is digital forensics laboratory?

Digital Lab - 5 SalvationDATA

Digital forensics is the preservation, identification, acquisition, recording and interpretation of digital data which mainly refers to computers, mobile devices, databases, audio and video terminal equipment, etc.

The digital forensics laboratory is a specialized area for investigation personnel engaged in the acceptance of computer-related crime cases, digital data exploration, investigation and evidence collection, data recovery, password cracking, identification analysis, evidence storage, process recording, and file filing management.

Why do we need an integrated digital forensics laboratory?

As digital storage media are diverse, a single forensics tool cannot meet the actual forensics needs of case investigators. As we know, digital storage media include digital audio tape (DAT), CD-ROM, writeable optical disks, magnetic tapes, and magnetic disks, as well as communications channels for local and wide area networks, LANs and WANs, respectively. Single digital forensics tool can only get data from one or two kinds of media. For example, a mobile forensics tool can only extract data from mobile devices, while it doesn’t work for computers or CCTV DVRs. However, a digital forensics laboratory could integrate various forensics tools in order to meet different needs of case investigators.

Digital forensics involves the processes of identification, preservation, analysis, documentation, and presentation. Let’s see each step in detail:

  • Identification

This is the first step in the digital forensic process. The identification process mainly includes the content of the evidence, where the evidence is stored, and finally, how the evidence is stored (in what format). The electronic storage medium can be a personal computer, smartphone, iPad, etc.

  • Preservation

In this step, the data is isolated, protected, and preserved. It includes preventing people from using digital devices to prevent digital evidence from being tampered with.

  • Analysis

At this stage, investigators reconstruct the data fragments and come to conclusions based on the evidence found. However, it may require countless inspections to support a particular crime theory.

  • Documentation

In this process, a record of all visible data must be created. This helps to recreate the crime scene and conduct inspections. It includes proper crime scene records, as well as photography, sketching, and crime scene mapping.

  • Presentation

The last step is the process of summarizing and explaining conclusions. However, it should be written in layman’s abstract terms. All abstract terms should refer to specific details.

Only an integrated digital forensics laboratory can cover all the above processes and form a closed loop.

 

In order to accord with the international standards and norms, the source of digital evidence, the standardization of the inspection process, the standardization of the authentication process as well as the transparency of evidence extraction. We need an integrated digital forensics laboratory to meet the requirements.

 

Law enforcement and judicial agencies urgently need to cultivate a large number of talents who are familiar with and proficient in digital forensics. An integrated digital forensics laboratory can help train and improve the comprehensive forensics skills and capabilities of case handling personnel. At the same time, it also provides a high-quality and professional user experience for case handling personnel.
