What this page is built from, and what it is not.
The mapping below is derived from 8 DISA STIG benchmarks (Google Chrome Current Windows, Kubernetes, Microsoft Windows 10, Microsoft Windows 11, Microsoft Windows Server 2019, Microsoft Windows Server 2022, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9) covering 2,030 rules, joined to 5,137 Control Correlation Identifiers.
It is not the complete STIG library. A control showing no rules here means no rule in these benchmarks maps to it, not that no STIG covers it. CCI to control mappings are published by DISA and reflect both Revision 4 and Revision 5 of NIST SP 800-53; where the two revisions disagree, both are shown. This page reports what the source data says and nothing further. It is not a compliance determination.
