Mitre Enginuity Mapping

[robmoffat]

This is what I mentioned in the Duplication Reduction meeting yesterday:

https://mitre-engenuity.org/cybersecurity/center-for-threat-informed-defense/our-work/nist-800-53-control-mappings/

"a comprehensive and open, curated set of mappings between 800-53 controls and ATT&CK techniques."

Something else to check out, a bit like @mlysaght2017 mentions in #203
