Title: Proposing a Digital Operational Forensic Investigation Process
Author(s): Madeleine Adrienne Bihina Bella, Martin Olivier, Jan Eloff

Keywords: Troubleshooting, operational forensics, digital forensics, forensic science, root cause analysis, failure analysis
Abstract: The increasing complexity of IT systems can lead to failures with disastrous consequences. In order to correct and prevent the recurrence of such failures, a thorough post-mortem investigation is required to localise their root causes. However, the currently used troubleshooting approach fails to provide sound analysis of these causes. A promising alternative approach is the emerging field of operational forensics, which applies digital forensic techniques to failure analysis with a view to improve the faulty system. This paper proposes a process for an operational forensic investigation, and shows how the process could be applied to a real-life IT failure to provide the correct diagnosis of the problem quicker and with more accuracy than troubleshooting. It also revisits the current definition of operational forensics in order to make it more specific.
