Structured systems economics for security management
Adam Beautement, David J. Pym · 2010
ABSTRACT. We develop an ontological account of information security architectures that is inspired by economic models of trade-offs between confidentiality, integrity, and availability. Our approach clarifies the nature of the trade-offs by making a clear distinction between declarative and operational concepts in security. We integrate this approach with a semantically justified mathematical systems modelling technology, thus providing a basis for a systematic methodology to support operational decision-making in information security investments and trade-offs. 1.
