A framework for expressing models of security policy
John E. Dobson, John A. McDermid · 2003
The authors first describe some issues that arise from the interplay between the security requirements for an integrated project support environment (IPSE) for the development of a trusted system, and the security requirements of the trusted system itself. All of these issues derive from security policy and the modeling of security policy. A framework is then presented which allows security policies to be expressed in the context of the enterprise whose needs the trusted system is intended to serve. Finally some possible applications of the framework are used to indicate how security policies affect design decision-making, security policy conflict detection, and security risk evaluation.>
