Statement

• Examine CUI for the presence of {{ insert: param, A.03.01.17E.ODP.01 }} when transferring information between different security domains.

• Prohibit the transfer of the CUI defined in 03.01.17E.a in accordance with the {{ insert: param, A.03.01.17E.ODP.02 }}.

Guidance

Unsanctioned information includes malicious code, information that is inappropriate for release from the source network, information that is not authorized to be stored or processed on the system, or executable code that could disrupt or harm services or systems on the destination network. This requirement enhances SP 800-171 requirement 03.01.03.
