EPA Moves From Warning to Enforcement on Water-Sector Cybersecurity
The Environmental Protection Agency is moving from warnings to active co-piloting with the water sector on cybersecurity.
The agency is using its role as risk-management lead for water utilities to help identify common vulnerabilities across drinking water and wastewater systems and to push out standardized incident-response and planning tools. This follows a year of increasingly visible attacks on small and mid-sized utilities, many of which still run flat OT/IT networks, leave remote access exposed, or operate with default passwords. EPA has already opened more than $9 million in grants for mid-to-large systems to harden their environments and is working alongside CISA to make cyber requirements part of routine water-utility planning. The intent is clear: get every utility to a demonstrable minimum standard before a foreign or criminal actor can disrupt treatment or distribution.
