Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
The control specifically requires architectures that minimize privacy risk when processing PII, directly addressing exposure of personal information.
Risk assessments evaluate exposure of critical functions lacking authentication and prioritize corrective controls.
Treats remote activation of surveillance-capable devices as a critical function that must be disabled or authenticated.
Requires established identification and authentication to unlock, mitigating missing authentication for continued system access.
Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
Automated marking identifies private personal information in outputs, tangibly reducing the ability to exploit weaknesses that result in its unauthorized exposure.
Privacy-specific attributes and their controlled association directly reduce exposure of private personal information through missing or incorrect labeling.
Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.
