1. A secure industrial control system, comprising:
an input/output module provisioned with a first unique security credential, the input/output module including a first memory device and a first processor coupled to the first memory device, the input/output module being operable to receive information from or send information to a field device; and
a control module provisioned with a second unique security credential, the second unique security credential indicating an original equipment manufacturer of the control module, the control module including a second memory device and a second processor coupled to the second memory device, the control module being configured to monitor and control the input/output module,
wherein the control module is configured to at least partially disable operability of the input/output module based upon an authentication process performed with the first unique security credential and the second unique security credential when the authentication process indicates a second original equipment manufacturer of the input/output module that is different from the original equipment manufacturer of the control module.
