NSA Guidance on Security IT-OT Interconnectivity

The NSA released another cybersecurity advisory on the need to secure the connections between Operational Technology (OT) networks and Information Technology (IT) networks.  Nothing really new for those working in the industry, but it is a reminder that we have to eliminate as many touchpoints to OT networks as we can.  Opening them to the IT networks only increases the attack surface that has to be defended.
