Reliable delivery matters as much as event generation. Design the channel around identity, integrity, replay handling and data minimization.
Evaluation approach
Define transport protection, identity context and duplicate handling. Bound queues, avoid sensitive payloads and measure event loss.
Application example
After an outage, process queued events using their original timestamps so they are not miscounted as a current attack surge.
Limits and considerations
Delayed or missing events are not automatically evidence of an attack.
Describe delivery guarantees accurately
Mobile events may arrive late, arrive twice or never arrive. Design queue limits, retries and deduplication. Missing server records do not prove that no device event occurred.
Separate mandatory decision evidence from telemetry for later investigation. A financial transaction must not rely solely on a log expected to arrive afterward. Schema versions and shared transaction identifiers preserve traceability across systems.
Checks and decisions
- Add event identifiers
- Bound queue size
- Monitor delivery rates
Keep telemetry distinct from immediate authorization for high-risk operations.
