NIST SP 800-53 Rev. 5 Common Control Library

Browse 1,193 controls and enhancements across 20 security and privacy families. Use the GovRAMP crosswalk to locate controls referenced by Security Snapshot, Core, and Moderate.

A shared catalog supports common-control planning; designation as a common, hybrid, or system-specific control depends on your organization’s implementation and inheritance decisions.

PT-3 · Personally Identifiable Information Processing Purposes

Control statement and discussion

NIST control statement

a. Identify and document the [Assignment: purpose(s)] for processing personally identifiable information; b. Describe the purpose(s) in the public privacy notices and policies of the organization; c. Restrict the [Assignment: processing] of personally identifiable information to only that which is compatible with the identified purpose(s); and d. Monitor changes in processing personally identifiable information and implement [Assignment: mechanisms] to ensure that any changes are made in accordance with [Assignment: requirements].

Discussion

Identifying and documenting the purpose for processing provides organizations with a basis for understanding why personally identifiable information may be processed. The term "process" includes every step of the information life cycle, including creation, collection, use, processing, storage, maintenance, dissemination, disclosure, and disposal. Identifying and documenting the purpose of processing is a prerequisite to enabling owners and operators of the system and individuals whose information is processed by the system to understand how the information will be processed. This enables individuals to make informed decisions about their engagement with information systems and organizations and to manage their privacy interests. Once the specific processing purpose has been identified, the purpose is described in the organization’s privacy notices, policies, and any related privacy compliance documentation, including privacy impact assessments, system of records notices, [PRIVACT](#18e71fec-c6fd-475a-925a-5d8495cf8455) statements, computer matching notices, and other applicable Federal Register notices. Organizations take steps to help ensure that personally identifiable information is processed only for identified purposes, including training organizational personnel and monitoring and auditing organizational processing of personally identifiable information. Organizations monitor for changes in personally identifiable information processing. Organizational personnel consult with the senior agency official for privacy and legal counsel to ensure that any new purposes that arise from changes in processing are compatible with the purpose for which the information was collected, or if the new purpose is not compatible, implement mechanisms in accordance with defined requirements to allow for the new processing, if appropriate. Mechanisms may include obtaining consent from individuals, revising privacy policies, or other measures to manage privacy risks that arise from changes in personally identifiable information processing purposes.

PT-3(1) · Data Tagging

View parent control
Control statement and discussion

NIST control statement

Attach data tags containing the following purposes to [Assignment: elements of personally identifiable information]: [Assignment: processing purposes].

Discussion

Data tags support the tracking of processing purposes by conveying the purposes along with the relevant elements of personally identifiable information throughout the system. By conveying the processing purposes in a data tag along with the personally identifiable information as the information transits a system, a system owner or operator can identify whether a change in processing would be compatible with the identified and documented purposes. Data tags may also support the use of automated tools.

SI-12 · Information Management and Retention

Control statement and discussion

NIST control statement

Manage and retain information within the system and information output from the system in accordance with applicable laws, executive orders, directives, regulations, policies, standards, guidelines and operational requirements.

Discussion

Information management and retention requirements cover the full life cycle of information, in some cases extending beyond system disposal. Information to be retained may also include policies, procedures, plans, reports, data output from control implementation, and other types of administrative information. The National Archives and Records Administration (NARA) provides federal policy and guidance on records retention and schedules. If organizations have a records management office, consider coordinating with records management personnel. Records produced from the output of implemented controls that may require management and retention include, but are not limited to: All XX-1, [AC-6(9)](#ac-6.9), [AT-4](#at-4), [AU-12](#au-12), [CA-2](#ca-2), [CA-3](#ca-3), [CA-5](#ca-5), [CA-6](#ca-6), [CA-7](#ca-7), [CA-8](#ca-8), [CA-9](#ca-9), [CM-2](#cm-2), [CM-3](#cm-3), [CM-4](#cm-4), [CM-6](#cm-6), [CM-8](#cm-8), [CM-9](#cm-9), [CM-12](#cm-12), [CM-13](#cm-13), [CP-2](#cp-2), [IR-6](#ir-6), [IR-8](#ir-8), [MA-2](#ma-2), [MA-4](#ma-4), [PE-2](#pe-2), [PE-8](#pe-8), [PE-16](#pe-16), [PE-17](#pe-17), [PL-2](#pl-2), [PL-4](#pl-4), [PL-7](#pl-7), [PL-8](#pl-8), [PM-5](#pm-5), [PM-8](#pm-8), [PM-9](#pm-9), [PM-18](#pm-18), [PM-21](#pm-21), [PM-27](#pm-27), [PM-28](#pm-28), [PM-30](#pm-30), [PM-31](#pm-31), [PS-2](#ps-2), [PS-6](#ps-6), [PS-7](#ps-7), [PT-2](#pt-2), [PT-3](#pt-3), [PT-7](#pt-7), [RA-2](#ra-2), [RA-3](#ra-3), [RA-5](#ra-5), [RA-8](#ra-8), [SA-4](#sa-4), [SA-5](#sa-5), [SA-8](#sa-8), [SA-10](#sa-10), [SI-4](#si-4), [SR-2](#sr-2), [SR-4](#sr-4), [SR-8](#sr-8).
