Methodology and Disclaimer
This coverage analysis maps from API 1164 clauses/requirements back to NIST SP 800-53 Rev 5 controls, assessing how well the SP 800-53 control set addresses each framework requirement.
Coverage weighting represents an informed estimate based on control-objective alignment, not a definitive compliance determination. Weightings consider whether SP 800-53 controls address the intent of each framework requirement, even where terminology and structure differ.
This analysis should be validated by qualified assessors for use in compliance or audit activities. The authoritative source for any compliance determination is always the framework itself.
