SC-32System Partitioning

Partition the system into {{ insert: param, sc-32_odp.01 }} residing in separate {{ insert: param, sc-32_odp.02 }} domains or environments based on {{ insert: param, sc-32_odp.03 }}.

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-284Improper Access Control4,832Enforces separation of domains that reduces the ability to bypass or violate access control boundaries.
CWE-732Incorrect Permission Assignment for Critical Resource1,824Supports correct permission assignment by allowing permissions to be scoped to individual partitions rather than a monolithic system.
CWE-285Improper Authorization1,230Partitioning limits authorization scope by confining subjects and objects to distinct environments.
CWE-668Exposure of Resource to Wrong Sphere779Prevents resources from residing in the wrong sphere by design through explicit domain separation.
CWE-250Execution with Unnecessary Privileges305Enables execution with minimal necessary privileges by isolating components into distinct environments.
CWE-669Incorrect Resource Transfer Between Spheres96Reduces incorrect transfers between spheres by establishing clear, separate domains for different sensitivities or functions.
CWE-441Unintended Proxy or Intermediary ('Confused Deputy')81Mitigates confused deputy risks by ensuring distinct privilege domains so one partition cannot unintentionally act on behalf of another.
CWE-653Improper Isolation or Compartmentalization52Directly implements isolation and compartmentalization by placing components into separate domains or environments.
