Framework overlap

Does ACSC Essential Eight cover CNCF Security Technical Advisory Group (TAG)?

You hold ACSC Essential Eight and have been told to do CNCF Security Technical Advisory Group (TAG). Here is how much overlaps, control by control.

29% of CNCF Security Technical Advisory Group (TAG) you already have

ACSC Essential Eight already covers about 29% of CNCF Security Technical Advisory Group (TAG), leaving 17 of 24 controls as genuinely new work.

Already covered 0 Likely covered 7 New work 17

No control in ACSC Essential Eight 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 ACSC Essential Eight 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.
