11 Rules for Ensuring a Security Model with AADL and Bell–LaPadula

In this SEI Podcast, Aaron Greenhouse, a senior architecture researcher with Carnegie Mellon University’s Software Engineering Institute, talks with principal researcher Suzanne Miller about use of the Bell–LaPadula mathematical security model in concert with the Architecture Analysis and Design Language (AADL) to model and validate confidentiality. Greenhouse and Miller also discuss 11 analysis rules that must be enforced over an AADL instance to ensure the consistency of a security model. Mapping Bell–LaPadula to AADL allows the expression of key concepts within the AADL model so that they can be analyzed automatically.
