Vihara Fernando
Abstract
With the development of technology, "Data", also interpreted as "Information" has become a major role played in the field of Cyber Forensics. One of the most crucial incidents which needs data to be important is, when it is taken as evidence in cyber-crimes. These crimes can be occurring in the fields of digital media and network in many instances related to crime scenes. Crime and forensic both investigators need the help of digital forensics to investigate in order to identify, whether the victim has committed a crime or not. Therefore, it is a requirement for an investigator to use a suitable, accurate, affordable and a reliable cyber forensic tool for the forensics investigations conducted with respect to crimes. Many researchers have done experiments on different functionalities, a forensic tool should have and have come up with various tools specifically for each branch in cyber forensics. Furthermore, with time, these cyber forensic tools have been identified with drawbacks due to the invasion of crimes, especially related to the sophisticated technology expansion. Therefore, the acquiring process of forensics tools is in lack of advanced features to detect evidence. This paper describes on some timely Digital Forensics tools and discusses emerging challenges in advanced areas of Digital Forensics.
