Security Architecture Review

Security architecture risk: 🔵 Low · up to ef113

The update changes only the pinned ClickHouse image. Credentials, storage configuration, startup dependencies, and the documented recovery workflow remain unchanged. No introduced security concern was established, but compatibility with existing database state and rollback to the previous image remains unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The directly evidenced scope is the example's ClickHouse service, its stored data, and the collector dependent on it. The supplied evidence does not establish production deployment or broader exposure.

Trust Boundaries and Controls

• observed — The collector and database retain the same otel username and shared password configuration. The healthcheck authenticates with those credentials and executes SELECT 1; it does not validate storage-format or application-schema compatibility.
