BFSI Sector is Increasing Adoption of Digital Forensic Techniques for Future Development
The process of preserving, identifying, extracting, and
documenting computer evidence that can be utilised in a court of law is known
as digital forensics. It is the science of extracting information from digital
media such as a computer, smartphone, server, or network. It equips the
forensic team with the most up-to-date techniques and tools for resolving
complex digital cases. Digital forensics assists the forensic team in
analysing, inspecting, identifying, and preserving digital evidence stored on a
variety of electronic devices.
Digital
forensics is a branch of forensic science that focuses on locating,
acquiring, processing, analysing, and reporting on electronically stored data.
Almost all illegal acts involve electronic evidence, and digital forensics
assistance is critical for law enforcement investigations. Computers,
smartphones, remote storage, unmanned aerial systems, shipborne equipment, and
other devices can all be used to gather electronic evidence. Digital
forensics' principal purpose is to collect data from electronic evidence,
convert it into actionable intelligence, and submit the results to the
prosecutor. To ensure that the findings are admissible in court, all processes
employ good forensic techniques.
Following is the Process of Digital Forensics-
·
Identification- In the forensic process, it is
the initial stage. What evidence is present, where it is held, and how it is
stored are all part of the identification process (in which format). Personal
computers, mobile phones, and personal digital assistants (PDAs) are examples
of electronic storage medium.
·
Preservation- Data is segregated, safeguarded,
and preserved during this phase. It includes restricting people from utilising
the digital device in order to prevent tampering with digital evidence.
·
Analysis- In this step, investigators piece
together data fragments and develop conclusions based on the evidence
uncovered. It may, however, take several iterations of investigation to
substantiate a single crime scenario.
·
Documentation- A record of all observable data
must be created during this process. It aids in the recreation and analysis of
the crime scene. It entails photography, sketching, and crime-scene mapping, as
well as adequate documenting of the crime scene.
·
Presentation- The process of summarization and
explanation of conclusions is completed in this final step. It should, however,
be written in layman's words with abstracted terminologies. The precise details
should be referenced in all abstracted terms.

A major problem impeding the growth of the digital forensics
industry is a lack of knowledge among small and medium businesses. Due to
financial constraints, small and medium-sized organisations (SMEs) are hesitant
to employ these forensics tools since they are costly and sophisticated.
Furthermore, SMEs face a manpower shortage, which is a key stumbling block to
the market's expansion. According to an analysis by the Institute of Electrical
and Electronics Engineers (IEEE), businesses in the United States have embraced
digital forensics technology to a large extent; however, European businesses,
particularly small and medium-sized businesses (SMEs), have yet to realise the
full potential of this technology.
