How to Secure Water and Wastewater OT Networks with Zero Trust

Water and wastewater utilities depend on connected SCADA systems, RTUs, telemetry units, pump stations, reservoirs, treatment plants, and chemical injection systems. Here’s how utilities can reduce cyber risk while protecting public health, safety, and operational continuity.

Step 1: Identify Critical Water and Wastewater Assets

Start by identifying SCADA systems, RTUs, remote telemetry units, pump stations, reservoirs, treatment plants, chemical injection systems, engineering workstations, vendor connections, and remote monitoring paths that require stronger protection.

Step 2: Review Exposure Across Remote Sites

Assess which systems are visible, remotely reachable, connected to vendors, or exposed through legacy remote access methods. Remote infrastructure is often widely distributed, making visibility and access control especially important.

Step 3: Cloak Sensitive OT Systems

Use network cloaking to make SCADA systems, RTUs, telemetry units, and other critical assets non-discoverable to unauthorized users, scanners, and AI-powered reconnaissance tools.

Step 4: Replace Password-Based Access

Deploy passwordless multi-factor authentication to reduce phishing, credential theft, shared-password risk, and unauthorized access to control networks.

Step 5: Secure Remote Monitoring and Maintenance

Provide secure remote access for authorized personnel, maintenance crews, engineers, and third-party vendors. Limit access to only the systems and time windows required for monitoring, maintenance, or repairs.

Step 6: Segment Critical Control Networks

Use segmentation and microsegmentation to isolate SCADA systems, RTUs, telemetry systems, chemical injection systems, and other high-risk assets into secure zones and conduits.

Step 7: Protect Legacy and Unpatchable Systems

Place Zero Trust access controls, cloaking, and segmentation around legacy OT devices that cannot be patched, upgraded, or interrupted without risking service disruptions.

Step 8: Reduce Ransomware Spread

Limit lateral movement by ensuring compromised users, endpoints, or vendor connections cannot freely traverse flat OT networks or reach unrelated control systems.

Step 9: Maintain Audit Trails for Compliance

Use access reporting, session visibility, and audit trails to support cybersecurity reviews, internal governance, and AWWA or EPA-related compliance requirements.

Step 10: Validate Resilience and Operational Continuity

Test whether unauthorized users, scanners, or AI-powered reconnaissance tools can still discover sensitive assets, access credentials, or move laterally across the water utility network. Then confirm that essential services can continue operating safely.
