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.
A data action map identifies locations where sensitive information may be exposed to unauthorized actors during processing or transfer.
The media protection policy defines requirements and procedures to prevent unauthorized disclosure or access to sensitive information on media.
Policies mandate protection of CUI on external systems, directly reducing unauthorized exposure of sensitive information.
Out-of-band delivery transmits sensitive data on a separate path, directly reducing exposure to unauthorized actors on the primary channel.
Wireless link protection (encryption, directional transmission, etc.) directly prevents unauthorized actors from observing transmitted data.
Automated marking applies security attributes to system outputs, making it harder for attackers to exploit unmarked sensitive information leading to unauthorized exposure.
Proper attribute retention and permitted-value enforcement limits unauthorized actors from accessing sensitive information lacking correct labels.
Prevents unauthorized exposure of sensitive information by prohibiting untrusted external systems from processing or storing it.
