The project identifies the initial security assurance requirements, normally from the profile; otherwise it takes the highest injury level from the system category, the highest threat category from the threat reports, the corresponding robustness level (section 7), the matching security assurance level, and the related requirements from section 8. This yields the most stringent level, adjusted later in design for cost-effectiveness.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
