Location: Room V1.04

Abstract: Runtime enforcement is a dynamic analysis technique that uses monitors to enforce the behaviour specified by some correctness property on an executing system. The enforceability of a logic captures the extent to which the properties expressible via the logic can be enforced at runtime. We study the enforceability of Hennessy-Milner Logic with Recursion (muHML) with respect to suppression enforcement. We develop an operational framework for enforcement which we then use to formalise when a monitor enforces a muHML property. We also show that the safety syntactic fragment of the logic, sHML, is enforceable by providing an automated synthesis function that generates correct suppression monitors from sHML formulas.

The talk is based on joint work with Luca Aceto, Adrian Francalanza and Anna Ingólfsdóttir that was presented at CONCUR 2018 is available at http://drops.dagstuhl.de/opus/volltexte/2018/9572/.
