UnverifiedCommon strategies for handling long contexts include sliding-window truncation, vector-retrieval-based memory systems (RAG), and historical content summary compression.68% similarUnverifiedSince malicious instructions largely originate from RAG-retrieved content and tool responses, deploying defenses only at the input entry point will miss the vast majority of the attack surface.68% similarUnverifiedIn practice, this requires a clear split in the pipeline from enterprise data lake to RAG: the vector index stays ignorant of identity, a thin, fast, synchronous authorization layer is retained to query the governance system directly on each retrieval request, scoped to the candidate documents returned by vector search, and monitored and alerted separately.67% similar
