Abstract: In any forensic investigation, planning and analysis activities are required in order to determine what digital media will be seized, what types of information will be sought in the examination, and how the examination will be conducted. Existing literature and suggested practices indicate that such planning should occur, but few tools provide support for such activities. Planning an examination may be an essential activity when investigators and technicians are faced with unfamiliar case types or unusually complex, large-scale cases. This article reports the results of empirical studies that evaluate two planning methods for planning computer forensics examinations: an experimental methodology that includes domain modeling and a typical planning method that does not include domain modeling. These studies were conducted to evaluate two research questions: Will the domain modeling of a computer forensics case during the planning phase result in an increased amount of evidence found in a digital forensics examination? Will an experimental “case domain modeling” methodology require a significant amount of additional effort when compared to a typical approach? Three experiment trials were conducted to evaluate the effectiveness of case domain modeling on simulated case scenarios. Analysis of the experiments indicates that case domain modeling in forensics planning requires an additional time investment and it can result in more evidence found during an examination and more effective keyword searches. Additionally, experimental data indicates that case domain modeling is most useful when the evidence disk has a relatively high occurrence of text-based documents and when vivid case background details are available.
