Usage Note: In the US, CPLYCUI may be used as a security label code to inform recipients of information designated by a US Federal Agency as Controlled Unclassified Information (CUI) to comply with the applicable laws, regulations, executive orders, and other guidances, such as included in DURSAs, to persist, mark, and enforce required CUI controls

Background:

In accordance with US 32 CFR Part 2002 and US Executive Order 13556 Controlled Unclassified Information, US Federal Agencies and their contractors are charged with classifying and marking certain information they create as Controlled Unclassified Information (CUI).

The following definitions, which are provided for context, are based on terms defined by the CUI Glossary https://www.archives.gov/cui/registry/cui-glossary.html

• CUI is defined as "information in any form that the Government creates or possesses, or that an entity creates or possesses for or on behalf of the Government, that a law, regulation, or Government-wide policy requires or permits an agency to handle using safeguarding or dissemination controls."
• Designating CUI occurs when an authorized holder, consistent with 32 CFR Part 2002 and the CUI Registry, determines that a specific item of information falls into a CUI category or subcategory.
• The designating agency is the executive branch agency that designates or approves the designation of a specific item of information as CUI.
• The authorized holder who designates the CUI must make recipients aware of the information's CUI status when disseminating that information.
• • Disseminating occurs when authorized holders provide access, transmit, or transfer CUI to other authorized holders through any means, whether internal or external to the agency.

Once designated as CUI, US Federal Agencies and their contractors must assign CUI marks as prescribed by the National Archives and Records Administration (NARA) CUI Registry, and display marks as prescribed by the CUI Marking Handbook.

CUI markings must be displayed on hard copy, on containers, electronic media, and to end users for IT systems.

When HL7 content is designated as CUI, these computable markings can be interoperably conveyed using HL7 security label CUI tags, and may be included in HL7 text and narrative elements as human readable markings.

Impact of CUI markings:

CUI Custodians must enforce CUI security controls per applicable CUI policies. Federal agencies and their contractors must adhere to FISMA and NIST SP 800-53 security controls. Custodians, who are not Federal agencies or agency contractors, and are receivers of CUI, must adhere to NIST SP 800-171 security controls and those dictated by the Authorities indicated by the assigned CUI markings.

For most participants in US healthcare information exchange, including Federal Agencies and their contractors, additional controls are required by HIPAA Security standards for health information US 42 USC 1320d-2(d)(2) https://www.govinfo.gov/content/pkg/USCODE-2016-title42/pdf/USCODE-2016-title42-chap7-subchapXI-partC-sec1320d-2.pdf

Federal Agencies and their contractors may be the CUI classifier of original CUI content; or a CUI derivative classifier, which reclassifies CUI content that has been aggregated with other CUI or Unclassified Uncontrolled Information (U) or dissembled from a larger CUI content; or declassifiers, depending on the designating agency's policies.

Applicable CUI policies include the following and any future applicable updates to policies or laws related to CUI:

• Executive Order 13556 https://www.federalregister.gov/articles/2010/11/09/2010-28360/controlled-unclassified-information
• US 32 CFR Part 2002 https://www.govinfo.gov/content/pkg/CFR-2017-title32-vol6/pdf/CFR-2017-title32-vol6-part2002.pdf

Usage Note: CPLYOPP may be used as a security label code to inform senders and receivers of information tagged with an ActCode_ActPolicyType_ActInformationPolicy.OrgIP code to comply with applicable organizational privacy policy.

Custodian security system must retrieve, evaluate, and comply with the organizational security policies associated with the target information.

Usage Note: CPLYOSP may be used as a security label code to inform senders and receivers of information tagged with an ActCode_ActPolicyType.SecurityPolicy code to comply with applicable organizational security policy.

Custodian security system must declassify information assigned security labels by instantiating a new version of the classified information so as to break the binding of the classifying security label when assigning a new security label that marks the information as unclassified in accordance with applicable jurisdictional privacy policies associated with the target information. The system must retain an immutable record of the previous assignment and binding.

Custodian system must strip information of data that would allow the identification of the source of the information or the information subject.

Custodian system must remove target information from access after use.

Custodian security system must downgrade information assigned security labels by instantiating a new version of the classified information so as to break the binding of the classifying security label when assigning a new security label that marks the information as classified at a less protected level in accordance with applicable jurisdictional privacy policies associated with the target information. The system must retain an immutable record of the previous assignment and binding.

Custodian security system must assign and bind security labels derived from compilations of information by aggregation or disaggregation in order to classify information compiled in the information systems under its control for collection, access, use and disclosure in accordance with applicable jurisdictional privacy policies associated with the target information. The system must retain an immutable record of the previous assignment and binding.

Custodian system must render information unreadable by algorithmically transforming plaintext into ciphertext.

Usage Notes: A mathematical transposition of a file or data stream so that it cannot be deciphered at the receiving end without the proper key. Encryption is a security feature that assures that only the parties who are supposed to be participating in a videoconference or data transfer are able to do so. It can include a password, public and private keys, or a complex combination of all. (Per Infoway.)

Usage Note: In security systems, security policy label assignments do not change, they may supersede prior assignments, and such reassignments are always tracked for auditing and other purposes.

Custodian system must render information unreadable and unusable by algorithmically transforming plaintext into ciphertext. User may be provided a key to decrypt per license or "shared secret".

Custodian must limit access and disclosure to the minimum information required to support an authorized user's purpose of use.

Usage Note: Limiting the information available for access and disclosure to that an authorized user or receiver "needs to know" in order to perform permitted workflow or purpose of use.

Custodian security system must persist the binding of security labels to classify information received or imported by information systems under its control for collection, access, use and disclosure in accordance with applicable jurisdictional privacy policies associated with the target information. The system must retain an immutable record of the assignment and binding.

Custodian must create and/or maintain human readable security label tags as required by policy.

Map: Aligns with ISO 22600-3 Section A.3.4.3 description of privacy mark: "If present, the privacy-mark is not used for access control. The content of the privacy-mark may be defined by the security policy in force (identified by the security-policy-identifier) which may define a list of values to be used. Alternately, the value may be determined by the originator of the security-label."

An originator must mark, persist, display, and convey computable and renderable Controlled Unclassified Information (CUI) marks as required by policy. A recipient must consume, persist, display, and reconvey CUI marks on information received based on agreements with the originator..

Examples:

• As CUI custodians, Federal Agencies and their contractors must mark, persist, display, and convey these marks.
• All CUI receivers must consume, persist, display, and reconvey CUI markings on information further disclosed
