Embodiments are directed to systems and methods for integration and normalization of physical security data, states and events to and from disparate physical security systems to maintain in real-time rules based policy state information to enforce physical security policies uniformly across network and information technology (IT) systems. Moreover it pertains specifically to such apparatus for providing an integration platform, methods and processes for normalizing data from physical security systems, to maintain physical security states, mapping to network access and either directly affecting the network equipment through standard programming commands or providing interfaces for network equipment and IT applications to query and determine physical security access states thus enforcing rules in real-time based on security systems data and events.
