Implementing NIST Privacy Framework IDENTIFY Function
Overview
The NIST Privacy Framework Version 1.0 (January 2020) provides a voluntary enterprise risk management tool structured around five core functions: IDENTIFY, GOVERN, CONTROL, COMMUNICATE, and PROTECT. The IDENTIFY function develops the organisational understanding to manage privacy risk arising from data processing. This skill covers the four IDENTIFY subcategories: Inventory and Mapping (ID.IM), Business Environment (ID.BE), Risk Assessment (ID.RA), and Data Processing Ecosystem Risk Management (ID.DE).
IDENTIFY Function Structure
ID.IM — Inventory and Mapping
Data processing inventory and mapping activities are understood by the organisation.
| Subcategory |
Description |
Implementation |
| ID.IM-P1 |
Systems/products/services that process data are inventoried |
Maintain a comprehensive register of all systems processing personal data, including SaaS tools, internal databases, and third-party integrations |
| ID.IM-P2 |
Owners of systems/products/services are identified |
Assign a data processing owner to each system with documented responsibility for privacy compliance |
| ID.IM-P3 |
Categories of individuals whose data are processed are inventoried |
Map all data subject categories (employees, customers, patients, vendors, website visitors) |
| ID.IM-P4 |
Data actions of the systems/products/services are inventoried |
Document data lifecycle actions: collection, retention, logging, generation, transformation, use, disclosure, sharing, transmission, disposal |
| ID.IM-P5 |
Purposes for data actions are inventoried |
Document specific purposes for each data action, aligned with GDPR Art. 5(1)(b) purpose limitation |
| ID.IM-P6 |
Data elements within the data actions are inventoried |
Catalogue all personal data elements processed per system and per purpose |
| ID.IM-P7 |
Environmental factors affecting the data processing ecosystem are understood |
Assess external factors: legal/regulatory requirements, industry standards, market expectations, organisational risk tolerance |
| ID.IM-P8 |
Data processing is mapped |
Create and maintain data flow maps showing how personal data moves through the organisation |
ID.BE — Business Environment
The organisation's mission, objectives, stakeholders, and activities are understood and prioritised.
| Subcategory |
Description |
Implementation |
| ID.BE-P1 |
The organisation's role in the data processing ecosystem is identified and communicated |
Determine controller/processor/joint controller status for each processing activity |
| ID.BE-P2 |
Priorities for organisational mission, objectives, and activities are established and communicated |
Align privacy programme with business objectives; ensure privacy is a design requirement |
| ID.BE-P3 |
Systems/products/services that support organisational priorities are identified and key requirements communicated |
Identify which processing activities are critical to business operations and prioritise privacy investment accordingly |
ID.RA — Risk Assessment
The organisation understands the privacy risks to individuals and how such processing creates privacy risks to the organisation.
| Subcategory |
Description |
Implementation |
| ID.RA-P1 |
Contextual factors related to the systems/products/services and data actions are identified |
Assess context: relationship with data subjects, data subject expectations, sensitivity, volume, collection method |
| ID.RA-P2 |
Data analytic inputs and outputs are identified and evaluated |
For data analytics and AI, identify inputs (training data, inference data) and outputs (predictions, scores, decisions) |
| ID.RA-P3 |
Potential problems for individuals that arise from data processing are identified |
Identify privacy harms: loss of autonomy, discrimination, economic loss, physical harm, reputational damage, loss of trust |
| ID.RA-P4 |
Problematic data actions, the likelihood that they occur, and the resulting problems for individuals are identified and assessed |
Assess likelihood and severity of each problematic data action — aligned with GDPR DPIA risk assessment |
| ID.RA-P5 |
Risk responses are identified and prioritised |
For each identified risk, determine response: mitigate, transfer, avoid, accept |
ID.DE — Data Processing Ecosystem Risk Management
The organisation identifies, assesses, and manages privacy risks associated with data processing by third parties.
| Subcategory |
Description |
Implementation |
| ID.DE-P1 |
Data processing ecosystem risk management policies, processes, and procedures are identified, established, assessed, and managed |
Vendor privacy management programme with due diligence, contractual requirements, and ongoing monitoring |
| ID.DE-P2 |
Data processing ecosystem parties are identified, prioritised, and assessed |
Map all processors, sub-processors, and third-party recipients with risk rating |
| ID.DE-P3 |
Contracts with data processing ecosystem parties are established, maintained, and managed |
Art. 28 DPAs with all processors; joint controller arrangements per Art. 26 |
| ID.DE-P4 |
Interoperability frameworks or mechanisms are established for data processing ecosystem parties |
Standard data formats, APIs, and privacy-preserving data exchange protocols |
| ID.DE-P5 |
Data processing ecosystem parties are managed consistent with the organisation's risk strategy |
Ongoing processor performance monitoring, audit rights exercise, sub-processor change management |

Implementation Methodology
Phase 1: Establish Inventory and Mapping (Months 1-3)
- Deploy a data discovery tool to identify personal data across all systems.
- Conduct departmental interviews to identify informal data processing.
- Create the system-level processing inventory (ID.IM-P1, P2).
- Map data subject categories (ID.IM-P3) and data elements (ID.IM-P6).
- Document data actions per system (ID.IM-P4) and purposes (ID.IM-P5).
- Create data flow maps (ID.IM-P8).
- Cross-reference with existing Art. 30 RoPA.
Phase 2: Business Environment Analysis (Month 2-3)
- Determine controller/processor/joint controller roles (ID.BE-P1).
- Align privacy programme priorities with business strategy (ID.BE-P2).
- Identify critical processing activities (ID.BE-P3).
Phase 3: Risk Assessment (Months 3-5)
- For each processing activity, assess contextual factors (ID.RA-P1).
- Identify problematic data actions using the NIST problematic data action taxonomy:
- Appropriation: use of data in ways beyond data subject expectations
- Distortion: use of inaccurate data or misleading inferences
- Induced disclosure: pressure to reveal more data than intended
- Insecurity: inadequate protection of data
- Re-identification: linking anonymised data back to individuals
- Stigmatisation: association with disfavoured groups
- Surveillance: excessive monitoring
- Unanticipated revelation: discovery of information beyond original data
- Unwarranted restriction: limiting access to services based on data
- Assess likelihood and severity for each problematic data action (ID.RA-P4).
- Determine risk responses (ID.RA-P5).
Phase 4: Ecosystem Risk Management (Months 4-6)
- Inventory all third-party data processors and recipients (ID.DE-P2).
- Conduct vendor privacy due diligence assessments.
- Verify DPA compliance for all processors (ID.DE-P3).
- Establish ongoing monitoring programme (ID.DE-P5).
Enforcement Context
While the NIST Privacy Framework is voluntary and not directly enforceable, organisations demonstrating NIST PF implementation show a mature privacy programme that can support GDPR accountability under Art. 5(2) and Art. 24. US state privacy laws (California CPRA, Virginia VCDPA, Colorado CPA) increasingly reference the NIST PF as a compliance resource.
