Weaknesses this control addresses (4)AI

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	5,385	Purpose-built components enable tighter, function-specific access-control enforcement that is harder to bypass than controls on general-purpose platforms.
`CWE-250`	Execution with Unnecessary Privileges	333	Specialized components can be engineered and configured to execute only the minimal necessary functionality and privileges for the essential service.
`CWE-653`	Improper Isolation or Compartmentalization	66	Dedicated specialized components isolate mission-essential services from general-purpose systems, strengthening compartmentalization.
`CWE-657`	Violation of Secure Design Principles	19	Specialization directly applies secure design principles (economy of mechanism, attack-surface reduction) by limiting critical functions to purpose-built components.
