Weaknesses this control addresses (8)AI-assisted
CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.
| CWE | Name | CVEs | Why this control addresses it |
|---|---|---|---|
CWE-284 | Improper Access Control | 8,100+ | Enforces separation of domains that reduces the ability to bypass or violate access control boundaries. |
CWE-732 | Incorrect Permission Assignment for Critical Resource | 2,000+ | Supports correct permission assignment by allowing permissions to be scoped to individual partitions rather than a monolithic system. |
CWE-285 | Improper Authorization | 1,700+ | Partitioning limits authorization scope by confining subjects and objects to distinct environments. |
CWE-668 | Exposure of Resource to Wrong Sphere | 800+ | Prevents resources from residing in the wrong sphere by design through explicit domain separation. |
CWE-250 | Execution with Unnecessary Privileges | 300+ | Enables execution with minimal necessary privileges by isolating components into distinct environments. |
CWE-441 | Unintended Proxy or Intermediary ('Confused Deputy') | 100+ | Mitigates confused deputy risks by ensuring distinct privilege domains so one partition cannot unintentionally act on behalf of another. |
CWE-669 | Incorrect Resource Transfer Between Spheres | 100+ | Reduces incorrect transfers between spheres by establishing clear, separate domains for different sensitivities or functions. |
CWE-653 | Improper Isolation or Compartmentalization | 85 | Directly implements isolation and compartmentalization by placing components into separate domains or environments. |
