Pomerium coverage
Pomerium can limit access to covered routes and provide identity-aware decision evidence. Operators still choose which identity, device, resource, event, and network data to collect, disclose, correlate, retain, export, and delete across identity providers, Pomerium, applications, and analytics systems.
Limits
- Confidentiality protects data from unauthorized disclosure. Privacy also concerns authorized processing that can create unwanted observation, inference, loss of control, or unfair consequence.
- Removing direct names does not make a dataset anonymous when identifiers, quasi-identifiers, behavior, metadata, or external data can reconnect records to people.
- Privacy controls must be evaluated for the real data, observer, auxiliary information, repeated releases, lifecycle, and human consequence.

Assess De-Identification and Inference
Test a dataset or query release against linkage, membership, attribute, reconstruction, rare-record, and repeated-release attacks.
Build a Privacy Threat Model
Model data actions, observers, linkability, inference, unawareness, loss of control, and human consequences across a complete system lifecycle.
Design Privacy-Preserving Security Telemetry
Collect enough access evidence for detection and investigation while limiting identity detail, linkability, sensitive content, recipients, and retention.
Minimize Identity and Access Data
Reduce claims, identifiers, device signals, policy inputs, assertions, logs, and retention to the minimum required for each access decision.

Concepts in this topic
Anonymization and Re-Identification
Evaluate whether a release resists identification and sensitive inference under realistic auxiliary data, recipients, repeated releases, and governance.
Differential Privacy
Bound how much a computation's output distribution can change when one person's contribution is added or removed.
Inference Attack
Derive protected facts from permitted queries, aggregates, models, correlations, errors, and repeated observations.
Linkability and Identifiability
Distinguish connecting events to each other from connecting them to a person, and bound both by observer, dataset, purpose, and time.
Personal Data and Metadata
Treat identifiers, device facts, access events, relationships, timing, locations, and derived attributes as personal when context can link them to people.
Privacy Engineering Objectives
Apply systems engineering to make personal-data processing predictable, manageable, and no more associated with people than the purpose requires.
Privacy Risk
Assess data actions that can create problems for people, then combine likelihood and impact without reducing privacy to breach risk.
Privacy-Enhancing Technologies
Select minimization, isolation, cryptography, confidential computation, controlled queries, and formal privacy from a precise data-use threat model.
Pseudonymization
Replace direct identity with a controlled reference while treating the mapping, stable links, attributes, and auxiliary data as remaining privacy risks.
Traffic Analysis
Infer participants, relationships, activity, protocol, content class, and events from communication timing, direction, size, frequency, and routes.
