Monitoring and Logging, as a technical privacy control within ISACA CDPSE's Privacy Architecture domain, is the systematic capture, storage, and analysis of events involving personal data — recording who accessed it, what was done with it, when it occurred, and under what authorization. It creates a tamper-evident audit trail that proves accountability, supports breach investigation, enables Data Subject Rights fulfillment, and demonstrates regulatory compliance. Privacy-aware logging is not simply a copy of security event logs: it must capture consent changes, policy enforcement decisions, and data processor activities while ensuring the logs themselves do not become a secondary source of personal data exposure.
Where it stops · what it isn't
- —IS: Capturing access events, consent changes, data modifications, policy enforcement decisions, and data processor activities involving personal data
- —IS: Pseudonymizing or encrypting log entries to prevent logs from becoming secondary privacy risk surfaces
- —IS: Architecturally separating event-metadata logs (what happened, when, by which role) from personal data content — logs record facts about actions, not the data acted upon
- —IS NOT: General IT operations logging (server uptime, CPU metrics) unless those events directly involve personal data handling
- —IS NOT: Full-content recording of personal data payloads within log entries — logging captures event metadata, not data content
- —IS NOT: A substitute for access controls, encryption, or other privacy controls — logging detects and evidences; it does not prevent
- —IS NOT: Unlimited data retention — log retention must comply with data minimization principles and be governed by a documented retention schedule
- —IS NOT: A one-time implementation — monitoring and logging is a continuous operational control requiring ongoing governance, review, and tuning
