The creation of it is usually very easy, however, the interpretation can be hard. This will be able to tell if you are properly developing the system of Forensic Investigations.
In this specific step, you will be working your best to recover the data from the file system. Based on file headers, carving files from the raw images, will be using tools and other types of techniques to further gather any of the addition evidence that you will be needing.
The very final step of this process is to report all of your results from the analysis. This may include the describing the actions that are being performed, determining if and what other actions are needing to be performed, and recommending improvements that may need to be done with procedures, tools, guidelines, policies, and other types of access to the forensic process.
