A holistic security architecture for distributed information systems : a categorical approach
Dimitris Sisiaridis, Nick Rossiter, Michael Heather · Northumbria Research Link (Northumbria University) · 2008
Distributed information systems (DIS) are free and open systems, characterized by their non-locality. Security for DIS, is a higher order activity, related to issues as data integrity and interoperability among complex heterogeneous systems. This proposed holistic security approach requires category theory. Security entities and distributed activities e.g. distributed transactions, in a DIS, are expressed as Cartesian Closed Categories and adjoint functors between them, following a four-level modular approach.
