+**Title:** Expressive Policies for Microservice Networks
+
+**Abstract:** Microservice-based application deployments need to administer safety
+properties while serving requests. However, today such properties can
+be specified only in limited ways that can lead to overly permissive
+policies and the potential for illegitimate flow of information across
+microservices, or ad hoc policy implementations.
+
+We argue that a range of use cases require safety properties for the
+flow of requests across the whole microservice network, rather than
+only between adjacent hops. To begin specifying such expressive
+policies, we propose a system for declaring and deploying service tree
+policies. These policies are compiled down into declarative filters
+that are inserted into microservice deployment manifests. We use a
+light-weight dynamic monitor based enforcement mechanism, using ideas
+from automata theory. Experiments with our preliminary prototype show
+that we can capture a wide class of policies that we describe as case
+studies.
