Framework overlap

Does NIST SP 800-218 cover CNCF Security Technical Advisory Group (TAG)?

You hold NIST SP 800-218 and have been told to do CNCF Security Technical Advisory Group (TAG). Here is how much overlaps, control by control.

42% of CNCF Security Technical Advisory Group (TAG) you already have

NIST SP 800-218 already covers about 42% of CNCF Security Technical Advisory Group (TAG), leaving 14 of 24 controls as genuinely new work.

Already covered 0 Likely covered 10 New work 14

No control in NIST SP 800-218 maps directly to one in CNCF Security Technical Advisory Group (TAG). Everything counted as covered is covered because both map to the same third standard, which is what a crosswalk is, but it is an inference rather than a lookup.

What is genuinely new work

How this is calculated

Already covered means a mapping runs from a control in NIST SP 800-218 to that control. Likely covered means no direct mapping exists but both frameworks map to the same control in a third standard. New work means neither. We keep those separate rather than adding them into one friendlier number, because blending them would present a two-hop inference as a verified fact.

Coverage is not symmetric. Run it the other way and you will get a different number; both are correct.

From 332,959 cross-framework control mappings across 723 frameworks, 531 of them verified against their source documents. It does not tell you that you are compliant: a mapped control means the two standards ask for the same thing, not that you have done it.
