Why it matters
Indirect prompt injection is the primary threat to production RAG and agentic systems, and this guide gives defenders concrete structural mitigations such as privilege separation, output schema enforcement, and document-level RBAC.
The article outlines seven defensive strategies to mitigate indirect prompt injection in corporate RAG pipelines, where attackers plant malicious instructions inside external documents that models ingest. Recommended controls include treating fetched documents as weaponized containers, enforcing data isolation, wrapping external content in randomized XML envelopes, deploying semantic classification to quarantine instruction-like chunks, and auditing egress output for leaked secrets, canary strings, and unauthorized tool calls.
