EtherNet/IP (includes CIP)

Description EtherNet/IP is an application layer protocol, treating devices on the network as a series of "objects". It is an implementation of the Common Industrial Protocol (CIP) over TCP/IP, compatible with ControlNet (CIP over a dedicated network) and DeviceNet (CIP over CAN bus) control systems. EtherNet/IP can be easily confused as a simple combination of Ethernet and the Internet Protocol. Instead, it is an industrial application layer protocol used for communication between industrial control systems and their components, such as a programmable automation controller, programmable logic controller or an I/O system.

EtherNet/IP Security Summary

Any device with a network connection to an EtherNet/IP controller can potentially change any of the controller’s key values.  Many controllers can even be reset, disabled, or loaded with new logic or firmware leaving them vulnerable and open to disruption or potential attackers.
