The water treatment plant compromise in Oldsmar, Florida on February 5 led city officials to reassess and upgrade security measures at the facility, some of which are starting to be disclosed. Last week, the city council unanimously approved an upgrade for the plant’s supervisory controls and data acquisition software that allows a local firm to replace the facility’s current computers and software. It will also install a “simplified yet robust program” used by other local utilities, including a nearby electric utility, as well as install additional security.
