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.
Establishes and maintains trust boundaries with external organizations before allowing their systems to interact with organization resources.
Prevents information from crossing trust boundaries without explicit approved authorizations.
Defining interfaces, controls, and trust responsibilities in agreements helps prevent violations of trust boundaries during data exchanges.
Authorizing and reviewing connections helps maintain proper trust boundaries between internal components.
Controlling media movement outside controlled areas maintains separation between internal and external trust boundaries.
Review of inter-system matching programs identifies and corrects trust-boundary violations before data crosses organizational or policy domains.
Defines explicit trust boundaries for PII use via documented purposes and prevents processing outside those boundaries.
Explicitly binding attributes to information crossing trust boundaries prevents loss of security context that leads to trust-boundary violations.
