Vector databases like Pinecone, Milvus, and Weaviate are central to modern AI applications. While they offer incredible performance for similarity search, they also introduce new security challenges that traditional SQL databases dont face.
The Risk of Prompt Injection
If your vector database queries are directly influenced by user input without proper sanitization, you risk "data exfiltration via retrieval." An attacker could craft prompts that force the retrieval of sensitive documents stored in your embeddings.
We recommend a multi-layered approach:1. Network isolation,2. Embedding-level access control, and3. Real-time request auditing via Sentinel-Pulse.
