Crosswalk a published crosswalk (NIST, ENISA, CIS, PCI SSC) makes the link · Editorial ControlMapping's judgement where no crosswalk exists; the reason is shown · Loosely related only shares a CSF 2.0 outcome: worth checking, not a mapping · No mapping in our data nothing mapped in our data; often new work, but check the coverage notes.
