The Forensic Analysis Process
We will now discuss the forensic analysis process. As a forensic investigator, you will need to create a strategy that will enable you to conduct an efficient investigation. You also need to make sure you are familiar with your tools and the results that they will provide. Without a process, you will waste time examining data that will not impact your investigation, and you will not be able to rely on your tools. In addition, you want to make sure you get valid results from the tools you deploy. Finally, to be thorough and efficient, you must use critical thinking to determine the best investigation or exam method.
While there are similarities in every investigation, you will find differences that will require you to have an exam strategy to be efficient. I am not a fan of keeping an examination checklist because there will be areas that aren’t relevant, such as different operating systems, physical topography of the network, criminal elements, and suspects. These variables ensure that no two examinations or investigations are the same and will require the investigator to execute a different strategy for each of them.
The forensic analysis process is made up of five subsets:
- Pre-investigation considerations
- Understanding case information and legal issues
- Understanding data acquisition
- Understanding the analysis process
- Reporting your findings
The upcoming sections will discuss each of these in greater detail.
