This page documents the existing security mechanisms in Jaeger, organized by the pairwise connections between Jaeger components. We ask for community help with implementing additional security measures (see issue-1718 ).

SDK to Collector

OpenTelemetry SDKs can be configured to communicate directly with jaeger-collector via gRPC or HTTP, with optional TLS enabled.

✅ HTTP - TLS with mTLS (client cert authentication) supported.
✅ gRPC - TLS with mTLS (client cert authentication) supported.
- Covers both span export and sampling configuration querying.

Collector/Ingester/Query-Service to Storage

✅ Cassandra - TLS with mTLS (client cert authentication) supported.
✅ Elasticsearch - TLS with mTLS (client cert authentication) supported; bearer token propagation.
✅ Kafka - TLS with various authentication mechanisms supported (mTLS, Kerberos, plaintext).

Browser to UI

✅ HTTP - TLS and bearer token authentication (pass-through to storage).

Consumers to Query Service

✅ HTTP - TLS with mTLS (client cert authentication) supported.
✅ gRPC - TLS with mTLS (client cert authentication) supported.
