An Insight into Digital Forensics: History, Frameworks, Types and Tools

The world is increasingly interconnected with the internet, which acts as a nervous system for every organisation. We can easily find interconnected devices in every home in the form of Smart devices, computer networks, and so on. The data generated by mobile devices increases rapidly because of the increase in the huge number of mobile devices, which takes more time in analysing the digital evidence. The objective of this chapter is to contribute to the history of digital forensics, the Evolutionary cycle, various investigation phases of digital forensics and give a detailed explanation about the types involved in digital forensics. This chapter demonstrates a brief study about how digital evidence plays an important role in investigation. In addition to this, we also explained the forensics tools as commercial bases as well as open-source software. During the investigation phase, determining the appropriate forensics tools depends upon the digital devices and Operating System. In some cases, multiple tools can be used to extract the full digital data.
