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

As water utilities become increasingly connected, secure remote access has become essential for maintaining operational technology while minimizing cyber risk. This NIST guide presents practical cybersecurity architectures that help water and wastewater organizations protect SCADA systems, remote facilities and industrial control environments. It explains how technologies such as multi-factor authentication, encryption, cloud-based access management, logging, network segmentation and least-privilege access reduce risk while supporting operational continuity. The guide also maps recommended practices to NIST CSF 2.0 and demonstrates real-world implementations using commercially available security technologies.
