Ex-NSA chief: Water system controllers don't belong on the internet

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

After suspected Iranian attacks on at least 12 US states' water systems, retired General and former NSA chief Paul Nakasone told DEF CON that programmable logic controllers (PLCs) should not be connected to the internet. He emphasized the need for higher security standards and partnerships, pointing to the DEF CON Franklin project and Project Chimera. The FBI has not officially attributed the attacks, but researchers suspect Iran.
