Agencies must ensure three things: every agency network is shielded by at least one gateway from networks belonging to other security domains; every gateway includes mechanisms that filter or restrict data flow, at both network and content level, to only what business purposes need; and every gateway component, whether discrete or virtual, is housed in a suitably secured server room.
This control maps to 2 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 2 it maps to, and the evidence behind each claim, over MCP and REST.
