Control Statement

The information system, when transferring information between different security domains, uses [Assignment: organization-defined data type identifiers] to validate data essential for information flow decisions.

Supplemental Guidance

Data type identifiers include, for example, filenames, file types, file signatures/tokens, and multiple internal file signatures/tokens. Information systems may allow transfer of data only if compliant with data type format specifications.
