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.
Defines isolation boundaries by specifying which external systems may access or process organization data.
Maintains isolation and compartmentalization by restricting flows between security domains or levels.
Controlling internal connections prevents exposure of resources to unintended internal spheres.
Locating systems away from hazards improves isolation and compartmentalization from external physical or environmental threats.
Directly requires isolation/compartmentalization of user services from system management functions.
Directly implements isolation and compartmentalization by placing components into separate domains or environments.
Explicitly distributes components to achieve compartmentalization, making it harder to exploit weak isolation boundaries between processing or storage elements.
The control is a direct realization of proper isolation and compartmentalization, eliminating the weakness of shared execution domains.
