Assuming one is operating in AWS and there are no ways to connect via a non-pts terminal, is it safe to blank the /etc/securetty file? Are there any possible unintended consequences? I can't think of any, but I'm just looking for a second opinion.

I found an answer I believe to be acceptable in the RHEL Security Guide:

To prevent the root user from logging in, remove the contents of /etc/securetty

    This is not the case on Ubuntu 20.04 LTS. Be sure to verify (run su - on a virtual terminal or Ctrl+Alt+F2 and log in as root) before assuming that this works.
