The internet originated in a DARPA project with communications capable of surviving a nuclear attack; the WWW originated as a way of communicating between data-intense science projects. ECommerce and social media originated as a way to exploit the internet for “trivial” purposes. With these additions, Security was substantially compromised. It is probably not possible to achieve adequate security. Secure communications likely require a separate network physically unconnected to the internet that the President uses to send tweets and accesses with an insecure phone.
