How Cyber Safe is Your Drinking Water Supply?
Amid multiple recent reports of hackers breaking into and tampering with drinking water treatment systems comes a new industry survey with some sobering findings: A majority of the 52,000 separate drinking water systems in the United States still haven’t inventoried some or any of their information technology systems — a basic first step in protecting networks from cyberattacks.
The Water Information Sharing and Analysis Center (WaterISAC) — an industry group that tries to facilitate information sharing and the adoption of best practices among utilities in the water sector — surveyed roughly 600 employees of water and wastewater treatment facilities nationwide, and found 37.9 percent of utilities have identified all IT-networked assets, with an additional 21.7 percent working toward that goal.
The ISAC found when it comes to IT systems tied to “operational technology” (OT) — systems responsible for monitoring and controlling the industrial operation of these utilities and their safety features — just 30.5 percent had identified all OT-networked assets, with an additional 22.5 percent working to do so.
