Keypoints
- Older water systems were built for durability, not internet connectivity.
- Internet-exposed OT and PLCs are major entry points for attackers.
- WaterISAC says insecure integrator access creates a serious risk.
- Small utilities often struggle with passwords, MFA, and basic cyber hygiene.
- WaterISAC is partnering with Cyware to speed cross-sector threat sharing.
