CVE-2023-21435

Monitoring directly detects unauthorized disclosure of sensitive information, enabling response to exposures.

Coordinating audit logging across organizational boundaries reduces the risk of sensitive audit data being exposed to unauthorized actors during transmission.

A data action map identifies locations where sensitive information may be exposed to unauthorized actors during processing or transfer.

The control's identification, isolation, alerting, and eradication steps directly limit the impact and exploitation window of unauthorized sensitive information exposure.

Requiring organization-defined processing conditions on specific PII categories directly reduces the chance that personal data will be exposed to unauthorized actors.

The assessment process surfaces design decisions that could expose sensitive (including PII) data to unauthorized actors, prompting controls that reduce such exposure.

Directly prevents exposure of critical organizational information by applying OPSEC processes across the SDLC.

Filtering output to only permitted content stops unintended disclosure of sensitive information to unauthorized actors.

Log generation configuration can and should exclude sensitive data, but the control statement focuses on availability rather than content filtering.

Secure SDLC practices directly prohibit writing sensitive data to logs; eliminating the weakness satisfies only one narrow slice of the control.

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.
