As part of the PA assessment package the CSP provides a supply chain risk management plan, under the FedRAMP+ controls SA-12 and SA-19, describing how it assesses and manages its supply chain and verifies component authenticity so that counterfeit, unreliable or maliciously altered hardware and software never make their way into the CSO's infrastructure or management plane.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
