Line 1: A '''controlled interface''' is a [[multilevel security]] system used to transfer low-classification data between security domains. The data to be transferred may theoretically move in either direction; the purpose of the controlled interface is to ensure that the data meets the criteria for transfer. This normally means that the data is of the lower classification. ~~One~~Examples ~~example is~~include the [[High Assurance Guard]] and the eXMeritus HardwareWall. The Committee on National Security Systems (CNSS) publishes the 'NATIONAL INFORMATION ASSURANCE (IA) GLOSSARY', also known as CNSS Instruction No. 4009. In this glossary, a Controlled Interface is defined as follows: "Mechanism that facilitates the adjudication of different interconnected system security policies (e.g., controlling the flow of information into or out of an interconnected system".
