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 | 4,832 | 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 | 305 | 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 | 52 | 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. |
