The NSC coordinated inputs from many agencies, such as DHS, which has the responsibility to protect critical infrastructure. > 4) Are commercial interests involved? 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. > 5) Are similar actions being taken in Canada or other countries? Nothing analogous to an executive order to my knowledge, but NPL in the UK offers something similar. https://www.npl.co.uk/npltime > 6) Is PNT singled out, or are there similar orders for other technologies and > risk profiles? 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. > 7) I don't see "leap second" or terms like "NTP" mentioned here.
