Abstract
The present invention relates to a system and methodology facilitating network security and data access in an industrial control environment. An industrial control system is provided that includes an industrial controller to communicate with a network. At least one security layer can be configured in the industrial controller, wherein the security layer can be associated with one or more security components to control and/or restrict data access to the controller. An operating system manages the security layer in accordance with a processor to limit or mitigate communications from the network based upon the configured security layer or layers.
