Agencies must ensure gateways: form the only communication paths in and out of internal networks; deny every inbound and outbound connection by default; permit only connections that have been explicitly authorised; are administered over a secure path that is kept apart from every connected network (meaning a dedicated administration network, or physical presence at the gateway itself); offer logging and audit capability good enough to detect intrusion attempts, information security incidents or anomalous patterns of usage; and generate real-time alerts.
This control maps to 3 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 3 it maps to, and the evidence behind each claim, over MCP and REST.
