Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Limiting P2P file sharing technology reduces inclusion of functionality or resources from untrusted external control spheres.
Enforcing installation policies prevents users from including functionality obtained from untrusted control spheres.
The inventory process requires identifying and recording the origin of all components, making inclusion of functionality from untrusted control spheres easier to detect during reviews.
Requiring approval and monitoring of maintenance tools prevents inclusion and execution of functionality obtained from untrusted sources.
Unowned portable devices represent untrusted control spheres; the prohibition prevents inclusion of functionality or data from such sources.
Strategy mandates assessment of third-party components and suppliers, directly reducing inclusion of functionality from untrusted control spheres.
Procedures can mandate supply-chain vetting and restrictions on functionality obtained from untrusted third-party or external control spheres.
Requires use of trusted sources and provenance tracking, tangibly limiting inclusion of functionality from untrusted control spheres.
