Security recommendations summary

Modern industrial automation requires direct interaction between machines performing specific functionality within an intelligent enterprise.

Limiting the communications between production nodes across an enterprise will also limit the functionality and performance of the enterprise and in some cases make the enterprise unsupportable.

Extreme care should be exercised when modifying any communication protocols, communication channels and ports, or operating system processes and services within a process control environment. proposed changes to the process control environment should be tested and modeled on a shadow system or plant model system before being implemented within the operating PCN or SCADA System.
