Abstract

Many software security policies can be encoded as aspects that identify and guard security-relevant program operations. Bugs in these aspectually-implemented security policies often manifest as ambiguities in which aspects provide conflicting advice for a shared join point. The design and implementation of a detection algorithm for such ambiguities is presented and evaluated. The algorithm reduces advice conflict detection to a combination of boolean satisfiability, linear programming, and regular language non-emptiness. Case studies demonstrate that the analysis is useful for debugging aspect-oriented security policies for several existing aspectual security systems.
