03.01.13E Metadata

Statement

Enforce information flow control based on {{ insert: param, A.03.01.13E.ODP.01 }}.

Guidance

Metadata is information that describes the characteristics of data. Metadata can include structural metadata that describes data structures or descriptive metadata that describes data content. The 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). This requirement enhances SP 800-171 requirement 03.01.03.

Statement

    • Adversary activities are restricted in scope, fail to achieve full effect, do not take place in accordance with adversary timeline, or require greater resources than adversary had planned.
