Likely Mitigating Controls AI

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.

addresses: CWE-497 CWE-668

Ongoing reviews detect and remove sensitive system information before it reaches publicly accessible systems.

addresses: CWE-497 CWE-668

Employs detection to prevent unauthorized mining of sensitive system information from being exfiltrated to external control spheres.

addresses: CWE-497 CWE-668

Documenting where system information is processed and stored prevents exposure to unauthorized control spheres.

addresses: CWE-668

Controls whether organization resources are exposed to external system spheres by permitting or prohibiting their use.

addresses: CWE-668

The control ensures information is not released into a security sphere where the recipient lacks matching access authorizations.

addresses: CWE-668

Restricts information flows to ensure resources are not exposed to incorrect or unauthorized spheres.

addresses: CWE-668

Controlling internal connections prevents exposure of resources to unintended internal spheres.

addresses: CWE-668

The control prevents exposure of the media resource to the wrong security sphere.

mitigates

Placing systems of differing trust levels into separate domains prevents resources from being placed in a sphere where they are reachable by unintended actors.

none

Requiring owners to manage the full asset life cycle and remove assets from the inventory upon secure disposal helps prevent resources from being inadvertently exposed outside their intended security sphere.

none

Keeping internal maps, directories, and signage from public view prevents disclosure of system or facility details that could aid reconnaissance or targeted attacks.
