Journal of Logic and Computation, is available online at: http://dx.doi.org/10.1093/logcom/exv020. abstract: We describe a uniform logical framework, based on a bunched logic that combines classical additives and very weak multiplicatives, for reasoning compositionally about access control policy models. We show how our approach takes account of the underlying system architecture, and so provides a way to identify and reason about how vulnerabilities may arise (and be removed) as a result of the architecture of the system. We consider, using frame rules, how local properties of access control policies are maintained as the system architecture evolves. date: 2015-06-12 publisher: Oxford University Press (OUP) official_url: http://dx.doi.org/10.1093/logcom/exv020 vfaculties: VENG oa_status: green full_text_type: other language: eng primo: open primo_central: open_green article_type_text: Article verified: verified_manual elements_source: Manually entered elements_id: 1021439 doi: 10.1093/logcom/exv020 lyricists_name: Pym, David lyricists_id: DPYMX87 full_text_status: public publication: Journal of Logic and Computation volume: 27 number: 1 pagerange: 41-80 issn: 1465-363X citation: Pym, D; Collinson, M; McDonald, K; (2015) Layered graph logic as an assertion language for access control policy models.
