Abstract: Techniques for determining and applying security decisions typically follow risk-based analytical approaches where alternative options are put forward and weighed in accordance to risk severity metrics based on goals and context. The reasoning or validity behind decision making can, however, prove difficult to determine in conditions characterised by uncertainty stemming from environments with insufficient or incoherent information. This paper approaches the problem by proposing a conceptual model that provides security decision making traceability through auditing decision makers’ rationalisation of risk. Additionally, the model highlights the role metacognition plays in identifying and understanding information affordances used for decision making.
