Control response
Mitigating Controls (NIST 800-53 r5) AI
Security engineering principles require disabling autocomplete on fields that accept private or sensitive data, directly preventing browser storage of such information.
Enforces secure configuration settings for web application input fields so that autocomplete is not enabled on sensitive forms.
Input handling routines can be designed to strip or ignore sensitive values that would otherwise be persisted by the browser.

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.
