ABSTRACT:
A system that facilitates enhanced security with respect to an industrial automation environment comprises a legacy device that is existent within an industrial automation system and a central access authority that provides access rules to a proxy. The proxy receives an access request directed to the legacy device and determines whether the access request is permitted based at least in part upon characteristics of the access request and the access rules provided by the central access authority.
