What is in this change?

Improve AWS CF template to use iptables to prevent an introspective query when deployed on an AWS EC2 instance using the special 169.254.169.254 IP and /latest/meta-data/* path to get metadata about the instance or otherwise.

This prevents the user from executing a "fetch website" on this domain by DROPing the request at the firewall level.

Developer Validations

  • I ran yarn lint from the root of the repo & committed changes
  • Relevant documentation has been updated
  • I have tested my code functionality
  • Docker build succeeds locally
