Initial application: merge from development to master branch

Summary

Requesting application to be hardened. This is only for initial hardening of a container.

Note: we are on standby to help with any greylist work and have some justifications on standby. We're just not 100% sure how to do that yet, so we appreciate your patience as we learn.
