I will teach cybersecurity basic lessons

Large utilities often have robust cybersecurity protections, but smaller water and electric power utilities and other small critical infrastructure providers do not. For example, In February, malicious actors attempted to tamper with the water supply of a small Florida city by hacking into a water treatment plant in Oldsmar, Fla. The attackers attempted to increase the level of lye in the city’s drinking water to dangerous levels but were quickly spotted, and the attack was mitigated before any changes were made to the water. A more savvy attacker could penetrate other utilities, and experts say that the Oldsmar incident should serve as a wake-up call to operators of public and private utilities — especially water utilities — to boost their cybersecurity controls.

That includes initiatives such as separating operational technology even more from IT and internet networks, enhancing password security and authentication at such facilities and updating old software to newer and more secure versions.
