CVE-2023-27465

Limits PII handling to authorized authority, making unauthorized exposure of sensitive information less likely.

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.

By enforcing authorization matching prior to sharing, the control reduces the risk of exposing sensitive information to unauthorized actors.

Review and removal of nonpublic information from publicly accessible systems directly prevents exposure of sensitive data to unauthorized actors.

Data mining protection mechanisms detect and block unauthorized bulk extraction of sensitive data, directly mitigating exposure to unauthorized actors.

Literacy training teaches users to recognize and avoid actions that result in unauthorized exposure of sensitive information.

Understanding stakeholder needs directly surfaces incompatible sensitivity expectations that produce the exposure.

Regulatory and privacy obligations often define the conflicting sensitivity views that the weakness fails to reconcile.

Establishing risk-management policy based on organizational context is the primary mechanism for aligning divergent sensitivity rules.

Periodic policy review can detect and correct stakeholder-policy mismatches before they cause exposure.

Defining and enforcing access policy is one concrete place where incompatible sensitivity decisions manifest as unauthorized disclosure.

A.5.1 only requires the existence of an information security policy and topic-specific policies (including on access control); it does not itself enforce compatible policies or stop the exposure that CWE-213 names, per the owner's explicit rule that such governance clauses do not prevent weaknesses

A.5.10 only requires awareness, a topic-specific acceptable-use policy stating expected behaviours/monitoring, and procedures referencing classification and other controls; per the owner's explicit rule on labelling and similar dependency-style clauses, this does not itself prevent exposure (CWE-200) unless access/DLP/etc. act on it.

Requiring the return of all physical and electronic assets plus secure deletion of organizational data from personal devices reduces the chance that sensitive information remains accessible to departing personnel.

A.5.12 only defines and communicates a classification scheme (a dependency for other controls); per the owner's explicit rule it performs no prevention itself on CWE-213, whose root cause is policy incompatibility rather than absent labels.

Labelling helps communicate classification decisions and reduce policy conflicts.

Transfer rules can enforce consistent protection when data crosses stakeholder boundaries.
