Emerging trends in Digital Forensic and Cyber security- An Overview

Digital forensics is the application of forensic and scientific knowledge to retrieve information legally from any digital device such as computers and smartphones. This legally fetched information is then presented as a piece of evidence in the courtroom further. Computer forensics also refers to digital forensics. It is the fusion of domains such as network forensics, server forensics, computer forensics, internet forensics, social media forensics, memory forensics, online gaming, data/disk forensics, and VR forensics. While investigating digital crimes, different steps are involved. These include the identification, recovery, investigation, validation, and presentation of evidence. Recent research has demonstrated the immense succession of cyber threats and attacks, requiring forensic experts and forensic scientists to simplify the digital world system. Since digital forensics is straightforwardly interconnected to data recovery and data carving, this area is dealing with different technical, legal, and resource challenges. In contrast to that, malware's constant rise allows forensic sector slacking. The objective of the present study was to explore new dimensions of digital forensics such as internet forensics, social media forensics, and IoT forensics in various emerging fields. Together, all our findings allow a better understanding of digital forensics, which can be helpful in forensic investigation.
