What it means
They rely on producers, brokers, topics, consumers, schemas, checkpoints, and retention policies. Security must cover both the transport path and the authority to publish or consume events.
Why it matters
High-volume streams can spread sensitive data or malicious input rapidly across many downstream systems.
Practical focus
- Authenticate producers and consumers separately
- Validate schemas and control sensitive fields
- Monitor lag, replay, unexpected volume, and unauthorized subscriptions
Common mistakes
- Using one credential for an entire event platform
- Retaining streams indefinitely without classification
- Trusting events merely because they originate inside the cloud
