What is the difference between CMMC 2.0 Level 1 and ISO 27001:2022?
CMMC 2.0 Level 1 is a other framework applying in the United States, with 17 controls across 6 domains. ISO 27001:2022 is a information security framework applying in International, with 93 controls across 6 domains. They govern different subjects, so the overlap is limited to the governance requirements they share. The mapping below shows where that is.
Measured coverage between these frameworks
We map controls between these two frameworks in a knowledge graph and have a person review every mapping before it is published. Below is what that review found. The figures are read live from the graph, not written by hand.
