Today, the White House issued an updated US National Cybersecurity Strategy document, building on a series of earlier initiatives and policies. This is available at

There's also a summary fact sheet at

There's a lot in this document, and of course many detailed questions about implementation,  and about prioritization of engagement with different sectors of critical infrastructure remain to be answered. Well worth reading.
