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.
Ongoing reviews detect and remove sensitive system information before it reaches publicly accessible systems.
Employs detection to prevent unauthorized mining of sensitive system information from being exfiltrated to external control spheres.
Documenting where system information is processed and stored prevents exposure to unauthorized control spheres.
The control stops sensitive system information from crossing into unauthorized control spheres through EM emanations.
Authorization and minimization requirements keep PII out of test/research control spheres that often lack production-grade protections.
Documented categorization of system information reduces the chance that sensitive internals are left exposed to unauthorized spheres.
System information is concealed or replaced with decoys, reducing leakage to unauthorized observers.
Ensures sensitive system information is not disclosed outside the intended control sphere through error output.
