Transit of important data, including to third parties, is protected. Partially achieved: all data links carrying important data are identified and protected, and data over untrusted carriers is protected (for example by cryptography) though confidence in robustness is limited. Achieved: protection over untrusted carriers with justified confidence in its robustness, and alternative transmission paths where failure, blocking or jamming could affect the essential function.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
