Item type:Publication, Access status: without files , Composition of least privilege analysis results in software architectures(Association for Computing Machinery (ACM), 2011-05); ; Security principles are often neglected by software architects, due to the lack of precise definitions. This results in potentially high-risk threats to systems. Our own previous work tackled this by introducing formal foundations for the least privilege (LP) principle in software architectures and providing a technique to identify violations to this principle. This work shows that this technique can scale by composing the results obtained from the analysis of the sub-parts of a larger system. The technique decomposes the system into independently described subsystems and a description listing the interactions between these subsystems. These descriptions are thence analyzed to obtain LP violations and subsequently composed to obtain the violations of the overall system.Publicationtype: Conference Paper11
