Abstract or Description

Abstract: "Miró is a set of languages and tools that support visual specification of file system security. We describe two visual languages: the instance language which allows specification of file system access, and the constraint language which allows specification of security policies. We present the syntax and semantics of these languages, and discuss some novel algorithms that efficiently check for properties, e.g., ambiguity, of instance pictures. We also describe the implementation of our tools and give examples of how the languages can be applied to real security specification problems."
