Cybersecurity for the Water and Wastewater Sector: Build Architecture (Operational Technology Remote Access)

The Water and Wastewater Systems (WWS) sector plays an important role in our national critical infrastructure. It is important that these utilities are equipped with resources to help them address and reduce their cybersecurity risks. Through the Cybersecurity for the Water and Wastewater Sector project, the NIST National Cybersecurity Center of Excellence (NCCoE) has built and demonstrated secure remote access architectures for operational technology in the water and wastewater sector using commercially available technologies. Developed in collaboration with technology vendors, water utilities, and other experts, this project produced three representative examples for implementing secure remote access for water utilities of different capacities. Each example outlines the architecture and configuration details of the solution.
