Abstract
Approaches for providing security for a programmable logic controller (PLC) are provided and include cloning a security module as a PLC proxy by copying at least one of a media access control (MAC) address and an internet protocol (IP) address of the PLC and determining, based on a predetermined security criteria, whether to route the message to the PLC. Based on the determination, the message is selectively routed to the PLC. So configured, by cloning the security module as the PLC proxy is effective to route network traffic intended for the PLC to the security module.
