Automatic event logging and record retention
Captures what an AI system did, when and with what inputs, and keeps those records long enough to reconstruct a decision, investigate an incident and demonstrate ongoing monitoring.

In brief
Automatic event logging and record retention is a technical measure, owned by the engineering lead and run continuously. 9 recorded duties in 2 jurisdictions rely on it, and it satisfies 4 of them outright. It produces 3 kinds of evidence an auditor can ask for.
How is it implemented?
Engineers define a log schema for each system that covers at minimum the time of use, the version of model and configuration, the inputs or their references, the output produced and any human intervention. Logs are written automatically, protected against tampering, access-controlled and retained for a period set by the strictest applicable rule and the organisation's own needs. Deployers confirm that logs generated under their control are retained and can be handed to the provider or an authority. Retention, deletion and access are reviewed periodically and the schema is updated when the system changes.
Which legal duties does it serve?
Satisfies means the control, operated properly, does the work the duty asks for. Supports means it contributes but the duty needs more. The official text decides; open it before relying on either.

What evidence shows it is operating?
| Evidence | Type | What it shows |
|---|---|---|
| AI system event logs | Access or activity log | System-generated records of use, versions, inputs, outputs and interventions, retained for the defined period. |
| Log schema and retention standard | Procedure or standard operating process | |
| Log integrity and retention check | Audit or assurance report |
Owner: Engineering lead. Frequency: continuous.
Which risks does it address?
Subdomains of the MIT AI Risk Repository, with the incidents the AI Incident Database has recorded under each. Counts are live; they say how often a risk has materialised, not how well this control prevents it.
- 7.4 Lack of transparency or interpretability AI system safety, failures, & limitations5 incidents · 42 risk entries
- 6.5 Governance failure Socioeconomic & Environmental3 incidents · 61 risk entries
- 2.2 AI system security vulnerabilities and attacks Privacy & Security24 incidents · 112 risk entries
Which standards clauses does it correspond to?
Clause numbers only. A reference means the standard asks for overlapping work, so evidence may be reusable; it never means the standard discharges a legal duty.
