En IT-forensikers kamp mot IT-brottsligheten : En studie om arbetssätt hos polisens IT-forensiker

Sammanfattning: The use of information technology (IT) is exploding. Today, it is in our daily routines to use some kind of information technology. The increase of users increases the number of cyber crimes, ie, crimes that in some way involve IT. As the cyber crimes grow in numbers, the workload for technical investigator increases, these are called digital crime investigators. The thesis is about how police digital crime investigators work and what problems they may encounter during an investigation. The result is based on physical interviews and surveys with a qualitative research method with semi-structured questions, ie interviews addressed to a person or a group where everyone gets the same questions. To further understand what a digital crime investigator do we recreated an authentic legal case focusing on filesharing from Nacka District Court. A scenario was created in which the suspect in the authentic case appealed the case and we were asked to verify the previous evidence. Our results showed that the working methods of the various digital crime investigators are basically the same with slight variations and that it requires a number of specific qualities to do the job. All 20 participants think that the job is exciting and fun, however it is not always pleasant and does include some negative aspects.
