AC-04(06) Metadata

Control

Enforce information flow control based on [Assignement: metadata].

Discussion

Metadata is information that describes the characteristics of data. Metadata can include structural metadata describing data structures or descriptive metadata describing data content. Enforcement of allowed information flows based on metadata enables simpler and more effective flow control. Organizations consider the trustworthiness of metadata regarding data accuracy (i.e., knowledge that the metadata values are correct with respect to the data), data integrity (i.e., protecting against unauthorized changes to metadata tags), and the binding of metadata to the data payload (i.e., employing sufficiently strong binding techniques with appropriate assurance).

Assessment Objective

information flow control enforcement is based on [Assignement: metadata].

Assessment Method

Examine

Access control policy information flow control policies procedures addressing information flow enforcement system design documentation system configuration settings and associated documentation types of metadata used to enforce information flow control decisions system audit records system security plan other relevant documents or records

Interview
