There has been a substantial and extensive use of Internet and technology in present day life which relatively has made the digital devices apropos to criminal investigations or legal prosecutions. Investigating huge amount of digital evidence consisting of data in various formats requires a digital forensic analysis (or cyber forensics). As the number of cases keeps on growing continuously, it is expected that the digital forensic analysis will increase significantly in near future. The forensic process involves the examination of digital devices which include computers, cell phones, devices supporting IoT, network formations like LAN’s, WAN’s etc. These varieties of digital evidence sources can anticipate new challenges for the investigation teams entrusted for imaging, analysis, storage and prosecution of the corresponding evidences. This paper reviews existing research literature and drafts the challenges from the technical standpoints and also elevates the estimation of future trends that could assist in more effective and robust digital forensic process.
