AC-4(7): One-way Flow Mechanisms
Enforce one-way information flows through hardware-based flow control mechanisms.
Supplemental
One-way flow mechanisms may also be referred to as a unidirectional network, unidirectional security gateway, or data diode. One-way flow mechanisms can be used to prevent data from being exported from a higher impact or classified domain or system while permitting data from a lower impact or unclassified domain or system to be imported.
