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 Control4,832Purpose-built components enable tighter, function-specific access-control enforcement that is harder to bypass than controls on general-purpose platforms.
CWE-250Execution with Unnecessary Privileges305Specialized components can be engineered and configured to execute only the minimal necessary functionality and privileges for the essential service.
CWE-653Improper Isolation or Compartmentalization52Dedicated specialized components isolate mission-essential services from general-purpose systems, strengthening compartmentalization.
CWE-657Violation of Secure Design Principles19Specialization directly applies secure design principles (economy of mechanism, attack-surface reduction) by limiting critical functions to purpose-built components.
