Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly enforces access control policies so that apps cannot read the sensitive data used for user fingerprinting.
Limits each app to the minimum set of data and privileges required, eliminating exposure of extraneous personal identifiers.
Ensures information placed in shared system resources is not retained or leaked to other apps after use.

CWE-359 does not impair RC.CO-04's ability to issue approved public recovery updates, yet any resulting PII exposure can partially undermine the outcome's overall efficacy and trust.

Masking or anonymizing personal identifiers limits the amount of private personal information that can be disclosed through application outputs or logs.
Monitoring and quarantining outbound messages that contain personal or private data directly reduces the chance that such information will be disclosed to unauthorized recipients.
The explicit prohibition on copying personally identifiable information into development and test environments directly lowers the exposure of private personal data to staff or processes that should not see it.
Labeling, chain-of-custody, and access-control requirements limit the exposure of private personal information during any transfer method.
Mandating privacy procedures and a designated privacy officer helps ensure that private personal information is not disclosed without proper authorization or necessity.
The agreements impose enforceable restrictions on the handling of private personal information, thereby decreasing the risk that such data will be exposed to unauthorized parties.
