Bridging Differences in Digital Forensics for Law Enforcement and National Security

Digital forensics approaches used by national security and law enforcement agencies have evolved along separate lines to serve different purposes. As a result, practices, tools, and techniques used by each agency group differ. The changing nature of national security threats and the increasing sophistication of domestic digital crime necessitates bridging the different approaches. This paper compares and contrasts the historic and current differences between digital forensics and describes how and why those differences must be bridged.
