CVE-2023-39508

Audit record review and analysis can detect unauthorized exposure or access to sensitive information.

Trained staff understand data-handling requirements and are less likely to expose sensitive information through misconfiguration or poor design.

Minimal information storage directly reduces the quantity of sensitive data resident on the component that could be exposed.

Policy promotes least privilege by defining necessary privileges and management commitment to them.

Supervision detects and allows removal of unnecessary privileges that enable execution with excess rights.

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.

Reviewing accounts for compliance, disabling/removing unneeded accounts, and aligning with termination processes prevents execution with unnecessary privileges.

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 so that protection needs can be understood; per the owner's explicit rule, labeling/classification does not itself prevent exposure and requires other controls (e.g. access enforcement) to act on it.

By requiring classification labels and metadata on all information assets, the control makes it harder for sensitive data to be inadvertently exposed because downstream systems and users can recognize and enforce handling rules based on those labels.

Requiring encryption, access controls, and recipient authentication for transfers directly reduces the chance that sensitive data reaches an unauthorized observer.

A.5.15's policy, requirements, and rules for determining/minimizing access rights (incl. privileged access restrictions, need-to-know, least-privilege-like mapping, and role-based consistency) directly stop most unnecessary-privilege execution by design; bounded remainder is runtime elevation or misconfigured enforcement that still requires other controls (e.g. 8.2, 8.3) to act.
