Abstract [en]

Due to the continued rise of diverse and sophisticated cyber-criminal activities, digital forensic investigations are becoming an essential part of various processes and workflows. It generates a vast amount of information where law enforcement agencies have to sift through and come to a certain conclusion based on the artefacts that were analysed during the investigation. While there are a plethora of analysis tools available that are employed during the digital investigation, the cyber- crime case that is being investigated may span across several countries. Thus, it is immensely difficult to fit into prosecution timelines and combine principal investigators with a particular area of expertise. The solution towards the problem is seen to be a coordination and collaboration process.

The thesis focuses mainly on how can coordination and collaboration of spread out forensic teams and individuals be supported to enable them to work together as a team towards a common goal. Taking into account the complexity and size of the cyber-crime problem space. To comprehensively achieve this, we propose FRIGG framework that aims to be a comprehensive platform.

FRIGG, primarily, is a coordination and collaboration framework that focuses on interactivity, sharing of the resources, information and knowledge to accomplish significant efficiency in the digital forensic investigation process

Intending to present FRIGG framework created in this thesis, a small scale prototype architecture with limited capabilities has been put together and tested. Small scale prototype concentrates around the secure distribution of evidentiary data, role-based access control, sustainability of the chain of custody, explicit evidentiary data delegation to certain digital forensic investigators based on the area of expertise, knowledge and information sharing. The results of the prototype implementation allow concluding that the architecture is feasible and enables coordination as well as the collaboration of spread out forensic teams or individuals to work together as a team towards a common goal.
