How Does the Milvus Vector Database Ensure Data Security?

This post details the implementation of user authentication and TLS connection in Milvus 2.1. User authentication is handled by the Milvus proxy, which intercepts gRPC requests and verifies credentials stored in etcd using bcrypt. The workflow for authentication and credential updates is described, along with configuration steps in `milvus.yaml` and SDK examples for connecting with credentials. TLS is enabled by configuring server and CA certificates in `milvus.yaml` and providing client certificates for SDK connections.
