In a [[multilevel security]] system, a '''controlled interface''' is a system component that is used to implement security constraints on the transfer of data between security domains. The data to be transferred may theoretically move in either direction; the task of the controlled interface is to ensure that the data meets the security criteria for transfer. In general, data can move from a lower-security doamin to a higher-security ___domain. For transfer in the opposite direction, it has to be ascertained that the data is of sufficiently low security sensitivity; for example, data [[Classified information|classified]] as "Secret" should not be allowed to leak into a ___domain that is merely "Restricted".
