Audit/review questions

Other than the classic "Show me", here are a bunch of generic questions to consider, select and refine if you are conducting an ISMS internal audit, IT audit, ISMS management review etc. looking into 'X' (an ISMS, situation, system, process, control, incident or whatever). Hopefully these are thought-provoking, helping you consider and explore X from different perspectives.
