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 policy and procedures establish internal controls and change management for system configuration settings, reducing the feasibility of external unauthorized modifications.
Baseline configuration under change control directly prevents unauthorized external modification of system or configuration settings.
Requires approval, documentation, and security impact review of all configuration changes, directly preventing unauthorized external control of system settings.
Impact analysis of configuration changes reduces the risk of deploying settings that permit unauthorized external control.
Restricting changes to system and configuration settings prevents external entities from controlling those settings without approval.
Establishing, implementing, approving deviations from, and monitoring configuration settings directly prevents external or unauthorized control of system settings.
The plan defines processes for identifying and managing configuration items, preventing external unauthorized control of system settings.
Vulnerability scanners directly detect externally controllable or misconfigured settings using standardized checklists.
