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.
Requires a managed development lifecycle process with integrity controls on changes, improving control of resources throughout their lifetime.
Requires designing resource lifetime controls that anticipate, withstand, and recover from stresses or attacks, mitigating improper resource control.
Directly enforces limited resource lifetime by requiring initiation from a known state and explicit termination, shrinking the window any long-lived resource weakness can be exploited.
