The stages of cybercrime investigations: Bridging the gap between technology examination and law enforcement investigation

Cybercrime investigation can be argued as still in its infancy. The technical investigation practices and procedures of global law enforcement are also still evolving in response to the growing threat of the cybercriminal. This has led to considerable debate surrounding the adequacy of current technical investigation models, examination tools and the subsequent capability of law enforcement to tackle cybercrime. To bridge the gap between low-level technology recovery and digital forensic examination, and to overcome the many technical challenges now faced by law enforcement; this paper presents an extended cybercrime investigation model capable of guiding the investigative practices of the broader law enforcement community. The Stages of Cybercrime Investigations discussed throughout this paper, demonstrate the logical steps and primary considerations vital to investigating cyber related crime and criminality. The model is intended to provide both technical and non-technical investigative resources, covering mainstream law enforcement, partner agencies and specialist technical services, with a formal and common structure when investigating the complex technical nature of cybercrime. Finally, the model is further aimed at providing cybercrime investigators with a means to consolidate understanding, share knowledge and communicate the resulting outcomes as an investigation moves through each relevant stage.
