Description
Software and firmware components prevented from installation unless signed with recognized and approved certificates include software and firmware version updates, patches, service packs, device drivers, and basic input/output system updates. Organizations can identify applicable software and firmware components by type, by specific items, or a combination of both. Digital signatures and organizational verification of such signatures is a method of code authentication.

ℹ️ Check
Verify the DNS server implementation is configured to prevent the installation of organization-defined software and firmware components without verification that the component has been digitally signed using a certificate that is recognized and approved by the organization. If the DNS server implementation is not configured to prevent the installation of organization-defined software and firmware components without verification that the component has been digitally signed using a certificate that is recognized and approved by the organization, this is a finding.
