This is a GCHQ Certified Training (GCT) course, with an independent GCT exam taken post course.
Updated for 2019/20, the Certificate in Digital Forensics Fundamentals course (QAIDIGFOR) is designed to help commercial and government organisations collect, preserve and report on digital artefacts in a way which is suitable for use in investigations.
The course covers the broad topics essential to the digital forensics’ disciplines. It sets out a framework for investigations, covering the best practice as described by The National Police Chiefs' Council (NPCC) formally ACPO guidelines. Forensic fundamentals will be covered as well as the use of open source forensic tools. The data will be then analysed, and an example report produced.
Participants to this course learn about the methods to identify, preserve, analysis and report on digital artefacts. Using a mixed approach of fundamentals and open source software, delegates will be able to select suitable tools and report on their findings in an evidential way.
The Certificate in Digital Forensic Fundamentals course audience includes all teams across the IT, Security, Internal Audit, Law Enforcement and Government.
