Runtime monitoring of cross-cutting policy

In open systems, certain unfavorable situations due to unanticipated user behavior may be seen, which results in a violation of cross-cutting policy. This paper proposes a runtime monitoring method to check such problems. Since there is a large gap, a certain link is needed between the policy and runtime execution method. We employ a two-step checking approach; an offline symptom checking and a runtime monitoring. The ingredient to tie the two steps is a Linear-time Temporal Logic formula for the cross-cutting policy to look at.
