The science of digital forensics is continually changing as technological advances are made and new digital devices are developed. This environment forces analysts to regularly extend their skills with training and frequent research to develop new and admissible techniques. Unfortunately, the same and similar methods are re-discovered by other analysts who are unaware of earlier peer efforts. The situation is aggravated by a nearly universal backlog in qualified digital forensics facilities. This leaves little time for communication between analysts even within a single agency. To address these issues and facilitate an increase in efficiency across all law enforcement agencies, we apply the lessons of knowledge management to digital forensics and extend them with special characteristics required by the law enforcement profession. The result is the development of the National Repository of Digital Forensic Intelligence. This system has been implemented in the largest accredited digital forensics lab in the world and is currently being extended to many other local, state, and federal agencies to increase effectiveness and efficiency among analysts.
