Use/Relationship: The purpose of the Security Evaluation Document (SED) is to provide
information about the architectural design of an Information Assurance (IA) product and its
intended detailed implementation throughout the development/design of the product. Sufficient
detail is provided to determine adequacy of the design and ensure that appropriate system
security requirements are met, while performing failsafe analysis of unauthorized events upon a
system as well as analysis of covert channels and anti-tamper design. The SED is used to
support security evaluations, and is a combination of previously used evaluation documentation
that included Covert Channel Analysis Report (CCA), Theory of Design and Operation (TDO),
Theory of Compliance (TOC), and Fail-Safe Design and Analysis (FSDA).
This Data Item Description (DID) is applicable to IA systems and is related to the system
security requirements supplied with the contract that references US Information Security
