The NSC coordinated inputs from many agencies, such as DHS, which has the 
responsibility to protect critical infrastructure.

This is an open ended question because one can play “six degrees of 
separation.”  https://en.wikipedia.org/wiki/Six_degrees_of_separation  The 
short answer is no—it originated within Government.

Nothing analogous to an executive order to my knowledge, but NPL in the UK 
offers something similar.  https://www.npl.co.uk/npltime

There are those in Government who view GPS insecurity as an example of, or 
analogous to, an IT security problem. Civilian GPS receivers receive 
unencrypted signals over-the-air and implicitly trust the data.  The idea here 
is apply the NIST Cybersecurity Framework 
https://en.wikipedia.org/wiki/NIST_Cybersecurity_Framework to this problem 
through the creation of “profiles.” So yes—one can say that this is one 
technology among many, though I don’t know if other EOs mandate use of the 
Cybersecurity Framework in other areas.

Right.

It’s a reference to this:
