SIEM integration improves visibility without requiring unlimited duplication of raw data. Decide schema, context, access and retention together.
Evaluation approach
Define mappings, timestamps and identity correlation. Control high volume and measure losses. Avoid transferring unnecessary sensitive data.
Application example
Correlate a RASP event with the API rejection for the same transaction instead of tracking device alarms alone.
Limits and considerations
Counting one event through several channels can exaggerate attack volume.
Monitor the event pipeline itself
A connected SIEM does not guarantee complete delivery. Measure delay, duplicates and loss. Schema mismatches can silently drop fields, so compare sample events end to end.
Link mobile, session and API records through shared identifiers. Check for unnecessary sensitive data. Define alert ownership and first-response steps before declaring the integration complete.
Checks and decisions
- Use shared event identifiers
- Handle clock differences
- Deduplicate records
Design the integration around the investigation questions it needs to answer.
