Abstract: Methods, systems, and computer-readable media for analysis of role reachability with transitive tags are disclosed. An access control analyzer determines a graph comprising a plurality of nodes and one or more edges. The nodes represent roles in a provider network hosting resources. The roles are associated with access control policies granting or denying access to individual resources. One or more of the access control policies grant or deny access based (at least in part) on one or more key-value attributes. The access control analyzer determines, based (at least in part) on a role reachability analysis of the graph, whether a first role can assume a second role using one or more role assumption steps for a particular state of the one or more attributes. The one or more attributes may comprise one or more transitive attributes that persist during the one or more role assumption steps.
