Updated for 2018, the Introduction to Digital Forensics course (QAIDIGFOR) is designed to help commercial and government organizations 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 introduction to digital forensic course audience includes all teams across the IT, Security, Internal Audit, Law Enforcement and Government.
