In a RAG system, the knowledge store is the foundation. It contains the documents, files, and records that the AI model retrieves when answering questions. Securing this repository is one of the most important steps in protecting the entire RAG pipeline. The knowledge store often takes the form of a vector database that holds embeddings of sensitive information. Even though these embeddings are mathematical representations, rather than raw text, attackers can sometimes reconstruct or infer the original content. This makes the vector store as sensitive as the original data itself. To protect it, organizations must apply the same controls used for critical databases. This includes enforcing strict access permissions, requiring authentication for all users and services, and encrypting data both at rest and in transit. Logging and monitoring should also be enabled to detect unusual access patterns that might indicate intrusion or data scraping attempts. When the knowledge store contains…
