Solution approach
Security Architecture
Translate threat assumptions into explicit trust boundaries, operational controls and recovery evidence.
Threat model
Translate threat assumptions into explicit trust boundaries, operational controls and recovery evidence.
Conceptual architecture. Select a component to inspect its responsibility.
Engineering the approach.
- Identify assets, entry points and likely failure paths.
- Define least privilege, isolation and control ownership.
- Test incident procedures and restoration in a scoped environment.
Define the boundaries.
A control diagram is not a security assurance. Verify enforcement, bypass paths and recovery against the actual runtime.
Delivery considerations
Agree acceptance criteria, integration ownership, failure handling and operational support before expanding the design. Validate the proposed architecture against the actual environment.
