New York finalized cybersecurity regulations for water and wastewater organizations, requiring covered utilities to implement baseline protections and prepare for disruptive cyber incidents. The rules include incident reporting, incident response and recovery planning, mandatory cybersecurity training for certified operators, and designation of a cyber lead for larger utilities. Coverage applies to community water systems serving more than 3,300 people, with additional obligations for larger organizations, as state officials cited escalating threats to the sector and the need to act despite stalled federal mandates.
The requirements also call for written vulnerability management procedures, stronger access controls such as multi-factor authentication, bans on default credentials, and segmentation of operational technology from IT and external networks; larger facilities must also conduct network monitoring and logging. To support compliance, the state launched a $2.5 million grant program and technical assistance effort, with funding available for cybersecurity evaluations and defensive upgrades. The measures were framed as a response to persistent targeting of water infrastructure, including campaigns linked to China and Iran, and as an effort to improve resilience and continuity of operations during cyberattacks.

State officials said the new requirements will take effect in 2027, with covered organizations required to comply by the end of 2026. Larger utilities will face added obligations such as appointing a cyber lead and conducting more extensive network monitoring and logging.
Alongside the new regulations, New York established the Strengthening Essential Cybersecurity for Utilities and Resiliency Enhancements grant program to help eligible utilities fund cybersecurity assessments and defensive upgrades. The program offers up to $50,000 for evaluations and up to $100,000 for improvements, with additional technical assistance available.
New York approved finalized cybersecurity regulations for community water systems and wastewater facilities, requiring measures such as incident reporting, vulnerability management, network segmentation, stronger authentication, and other security controls.
