As A Branch Of Cybersecurity, Digital Forensics Is Concerned With The Recovery And Investigation Of Data Found On Digital Devices And Cybercrime

 

Digital Forensics

Digital Forensics gathers, retains, examines, and provides computer-related evidence in support of criminal, fraud, counterintelligence, or law enforcement investigations as well as network vulnerability mitigation. In its strictest sense, the use of computer science and investigative techniques involving the examination of digital evidence – in accordance with appropriate search authority, chain of custody, mathematical validation, use of validated tools, repeatability, reporting, and potentially expert testimony.

According To Coherent Market Insights, The Global Digital Forensics Market Was Valued At US$ 4,501.0 Mn In 2019 And Is Expected To Reach US$ 9,453.0 Mn By 2027 At A CAGR Of 10.8% Between 2020 And 2027.

Digital Forensics is the application of science to the recognition, gathering, inspection, and analysis of data while upholding the data's integrity and adhering to a rigid chain of custody. A comprehensive incident response strategy must include Digital Forensics as a key component. As a result, the company should address it through its rules, practises, budgets, and staff. The effectiveness of the digital forensic process should be maximised in the writing of all relevant policies and procedures. Drafting specific policies to address digital forensic techniques and issues is necessary. The budget should allocate expenditures for the equipment and instruction required to enable an incident response in order to properly reflect the value of digital forensics.

A sufficient number of employees should receive training in the foundations of forensics and certification for the particular instruments they will use. A crucial idea in Digital Forensics is validation. To achieve that goal, it is crucial to keep staff who are both qualified and certified.

Initially, only computers, primarily personal computers, were included in the discipline of digital forensics. The word "computer forensics" has become too narrow to describe the entire profession during the past 20 years as computers have connected through local networks, then the Internet, which is the greatest network of them all. As a result, the majority of examiners who specialise in areas other than computer forensics now refer to their field as Digital Forensics.

Network forensics is now a subfield of Digital Forensics, and it involves areas of expertise including looking at network security lapses, hacking attempts, and data theft. The area has grown to include more subdisciplines as a result of the integration of computer processing into other devices, including global positioning system (GPS) units, cars, truck black boxes, cellphones, answering machines, copy and fax machines, and so on. A digital forensic examiner can have knowledge in any of the subdisciplines, although not all of them must. Some examiners opt to concentrate in a single field, such as computer forensics, never learning about GPS or mobile phone forensics.
