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.
Use of granular security and privacy attributes enables finer access control than coarse permission models alone.
Documenting interface characteristics enables more granular control over internal access.
Requires the architecture to describe granularity and placement of controls, preventing insufficiently fine-grained access decisions.
Provides the necessary granularity by placing system management functions outside the reach of user-level access controls.
Isolation supplies an explicit, enforceable granularity boundary between security and non-security functions that coarser access-control schemes lack.
