At their Geneva summit meeting, U.S. President Joe Biden handed Putin a list of 16 critical infrastructure sectors that must be "off limits" from cyber attacks.
"I talked about the proposition that certain critical infrastructure should be off-limits to attack, period, by cyber or any other means," the president stated. "I gave them a list, and I don't have it in front of me, if I am not mistaken, of 16 entities — 16 defined as critical infrastructure, from the energy sector to our water systems." — Yahoo News

Is it known what sectors (or specific entities) are in this list?
I found Homeland Security Presidential Directive 7: Critical Infrastructure Identification, Prioritization, and Protection, but it looks rather dated (December 2003), contains a fewer number of entities, and mostly covers a "regular" terrorism like bombing etc while touching cyberspace rather tangentially.
Looking for a better source.
