CVE-2023-42534

Controls on authorized publication limit files and directories with nonpublic data from becoming accessible to external parties.

Controlling and documenting P2P file sharing prevents files and directories from being made accessible to external parties for unauthorized distribution.

Identifying and documenting file and directory locations allows restriction of access to external parties.

Protecting backup files ensures they are not accessible to external parties or unauthorized spheres.

Sanitizing equipment before off-site maintenance reduces the risk of files or directories containing sensitive data becoming accessible to external parties.

Policy restricts media access to authorized parties only, preventing exposure of resources to external or unauthorized actors.

Media access restrictions prevent files or directories from being accessible to external parties.

Employing and evaluating controls at documented alternate sites makes files and directories less likely to be accessible to external parties through physical or environmental weaknesses.

Data-at-rest protections such as encryption or ACLs reduce the impact of unintended file exposure.

Hardened configuration baselines commonly include file-system permission settings that limit external access.

By tracing and retrieving all copies of information stored on endpoint and portable devices, the control reduces the likelihood that files remain accessible outside the organization’s security perimeter.

Labeling information according to its sensitivity and specifying corresponding protection measures makes it less probable that files or directories containing sensitive content will be left accessible to external parties.

Including asset location and ownership in the inventory, combined with secure disposal procedures, decreases the chance that files or directories remain accessible to external parties after they should have been removed or restricted.

Solid perimeters and locked external access points stop files, devices, or directories containing sensitive data from being reachable by external parties who could otherwise walk in or break in.

Authorizing and logging the removal of storage media, disabling unused ports, and monitoring transfers limit the exposure of files or directories to external parties outside the organization’s controlled environment.

Segregating delivery/loading zones and controlling external doors prevents external parties from reaching directories or resources that should remain inaccessible.
