Nobody tracked the cellular modems on water controllers
The devices showed up on carrier invoices but never in an IT asset inventory. Matching the two costs nothing and can start Monday.
In July, intruders compromised water and wastewater controllers across multiple states through an exposure no asset inventory caught: the devices were connected to public cellular networks, not the city LAN. The modems appeared on carrier invoices but nowhere on network scans. The former CIO of Waco, Texas, writing from direct experience, argues the core problem isn't technical. No single person owns accountability for the whole municipal network. Matching carrier invoices to actual devices costs nothing in tools or headcount and can start this fiscal year with money already in a budget request.
