The legal ground that makes a processing activity permissible, such as consent, contract, legal obligation, vital interest, public task or legitimate interest.

- Related: Lawful Basis, Data Minimisation, Compatibility Assessment
The principle that personal data may only be used for the specific, explicit and legitimate purposes stated when it was collected, unless a compatible new purpose applies.

Collecting and retaining only the personal data that is adequate, relevant and necessary for the stated purpose, avoiding surplus fields and indefinite retention.

A freely given, specific, informed and unambiguous indication of agreement, withdrawable at any time and requiring evidence that it was validly obtained.
- Legitimate Interest
- Related: Lawful Basis, Legitimate Interest Assessment
A lawful basis relying on a genuine business or third-party interest that is not overridden by individual rights, documented through a balancing assessment.
- Data Classification
- Related: Data Inventory, Data Minimisation, Access Control
Assigning data to defined sensitivity tiers so that handling, access, retention and protection requirements are proportionate and consistently applied.
- Data Inventory
- Related: Data Classification, Records of Processing Activities, Data Flow Mapping
A maintained catalogue of datasets recording what personal data exists, where it resides, who owns it, how it flows and why it is held.
- Records of Processing Activities (ROPA)
- Related: Data Inventory, Accountability, Data Flow Mapping
The formal register of processing operations, describing purposes, categories of data and individuals, recipients, transfers, retention and security measures.
- Data Flow Mapping
- Related: Data Inventory, Cross-Border Transfer, Records of Processing Activities
Diagramming how data moves between systems, teams and external parties, capturing collection points, transfers, storage locations and onward disclosures.
- Retention Schedule
- Related: Data Minimisation, Erasure, Data Classification
A rule set defining how long each data category is kept and how it is disposed of once the purpose or legal retention period ends.
- Defence in Depth
- Related: Access Control, Encryption at Rest, Zero Trust
Layering independent preventive, detective and corrective controls so that the failure of one safeguard does not expose the data protected by the others.
- Zero Trust
- Related: Least Privilege, Multi-Factor Authentication, Defence in Depth
A security model that verifies every request explicitly and grants least privilege, rather than trusting users or devices because of their network location.
- Pseudonymisation
- Related: Anonymisation, Encryption at Rest, Key Management
Replacing direct identifiers with tokens so that data can no longer be attributed to an individual without separately secured additional information.
- Anonymisation
- Related: Pseudonymisation, Re-Identification Risk
Irreversibly transforming data so that no individual can be identified by any means reasonably likely to be used, taking account of singling out and linkage.
- Encryption at Rest
- Related: Encryption in Transit, Key Management, Defence in Depth
Protecting stored data by converting it into unreadable ciphertext, so that lost media or unauthorised storage access does not expose the underlying content.
- Encryption in Transit
- Related: Encryption at Rest, Cross-Border Transfer
Protecting data while it moves across networks using protocols such as TLS, preventing interception or tampering between sender and recipient.
- Key Management
- Related: Hardware Security Module, Encryption at Rest, Cryptographic Agility
The lifecycle discipline of generating, storing, rotating, escrowing, revoking and destroying cryptographic keys with separation of duties and audit trails.
- Hardware Security Module (HSM)
- Related: Key Management, Cryptographic Agility
A tamper-resistant device that generates and stores keys and performs cryptographic operations so that key material never appears in plain form on general systems.
- Cryptographic Agility
- Related: Key Management, Post-Quantum Cryptography
Designing systems so that algorithms, key lengths and providers can be replaced quickly without redesigning applications, in response to new threats or standards.
- Least Privilege
- Related: Role-Based Access Control, Zero Trust, Privileged Access Management
Granting each identity only the minimum access needed for its current task, for the shortest time, and removing it when no longer required.
- Role-Based Access Control (RBAC)
- Related: Least Privilege, Access Review
Assigning permissions to job roles rather than individuals, so that users inherit rights through their role and access stays consistent and reviewable.
- Multi-Factor Authentication (MFA)
- Related: Zero Trust, Privileged Access Management
Requiring two or more independent authentication factors, such as something known plus something held, to reduce the impact of stolen credentials.
- Privileged Access Management
- Related: Least Privilege, Multi-Factor Authentication, Access Review
Controls over high-power accounts, including vaulting of credentials, just-in-time elevation, session recording and frequent review of administrative rights.

- Forensic Readiness
- Related: Incident Response Plan, Breach Notification
Preparing logging, time synchronisation, evidence handling and chain-of-custody procedures in advance so incidents can be investigated and defended credibly.
- Data Processing Agreement (DPA)

- Cross-Border Transfer
- Related: Standard Contractual Clauses, Transfer Impact Assessment, Data Flow Mapping
Moving personal data to another jurisdiction, permitted only where a transfer mechanism and, where required, additional safeguards and assessments are in place.

An analysis of the destination country's laws and practices, and of supplementary measures, to judge whether transferred data retains equivalent protection.
- Privacy by Design
- Related: Privacy by Default, DPIA, Data Minimisation
Embedding privacy protections into system architecture and default settings from the outset, rather than adding compliance measures after the design is fixed.
- Privacy Enhancing Technologies (PETs)
