SC-7(27) Unclassified Non-national Security System Connections
Control enhancement of SC-7 Boundary Protection
Control
Prohibit the direct connection of [Assignment: unclassified, non-national security system] to an external network without the use of [Assignment: boundary protection device].
Discussion
A direct connection is a dedicated physical or virtual connection between two or more systems. Organizations typically do not have complete control over external networks, including the Internet. Boundary protection devices (e.g., firewalls, gateways, and routers) mediate communications and information flows between unclassified non-national security systems and external networks.

We assess where you stand against this control, document the gap, and build the remediation plan your auditor and your board will both accept.
