President Trump postponed signing an executive order related to cybersecurity today, with no reason specified, according to NBC News, story here.
The president talked to some tech security companies today, and made a brief statement. It is interesting that President Trump mentioned the power grid as a possible target, as so well documented in Ted Koppel’s book “Lights Out”. I have actually tweeted "RealDonaldTrump" directly on this issue.
The president could tighten rules about network topology that even allows it to be possible to access the power grids or other infrastructure, or that makes components (like transformers) vulnerable to sabotage.
