Investigators are under increasing pressure to respond to challenges that the wide range of digital evidence sources and the diverse range of digital devices presents. In addition to laptops, computers and mobile devices, today’s sources of digital evidence include network shares, Cloud Storage, IoT and more. Traditional digital forensic workflows often prevent an investigator from efficiently dealing with Big Data challenges. Key facts are often spread across multiple evidence sources and an investigation is typically multi-dimensional encompassing multiple people, objects, locations and events. Investigators need more efficient workflows to strive for Intelligence Driven Investigations that harness the power of big data, rather than becoming swamped by it. This includes collaboration across geographic and jurisdictional boundaries, sharing of intelligence and being able to identify hidden connections across large numbers of evidence sources.
