CISO's Guide to Vector Database Security
Vector databases, which store embeddings of enterprise data to enable semantic search and AI applications, face significant security risks if improperly protected. Organizations must establish data governance, classification, and access controls before sensitive information is indexed, secure databases with encryption and authentication, and restrict application access using least-privilege principles.
CISOs should inventory existing deployments, classify data by sensitivity, apply defense-in-depth strategies including centralized logging and monitoring, and treat retrieved content as untrusted to mitigate threats like unauthorized retrieval, data poisoning, and prompt injection attacks.
