Discloses the device's ability to keep transmitted PII intact: whether it supports a mechanism, digital signatures for example, that protects data from alteration while in transit (TXIG-1); and whether the device is made of several sub-components linked by external cabling, with a system diagram referenced where possible (see DOC-10) (TXIG-2).
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
