Water system controllers don't belong on the internet, says ex-NSA chief

At least 12 US states' water systems have been hacked, likely by Iran, targeting programmable logic controllers (PLCs) that manage critical infrastructure operations. Retired General Paul Nakasone, former NSA chief, argues that these controllers should not be connected to the internet and calls for higher cybersecurity standards and collaborative defense partnerships across the 50,000 water municipalities in the US. While security researchers suspect Iranian involvement, federal officials have not yet officially attributed the attacks despite Iran's documented history of targeting water facility infrastructure.
