UnverifiedThe approach to defending against prompt injection is not stricter prompt filtering, but assuming injection will eventually succeed and placing controls in tool permissions, retrieval authorization, and output destinations.71% similarUnverifiedA pre-authorization mechanism strips authorization decisions away from the agent itself and assigns them to a deterministic rules engine independent of the model, drawing on the ideas of continuous verification and never trusting by default from zero-trust security architecture.71% similarUnverifiedAny agent with financial permissions should treat human approval or hard-rule validation as the last line of defense, rather than fully trusting model decisions.71% similarUnverifiedTight grounding mode is used in scenarios involving regulation and compliance, where model responses must be strictly anchored to retrieved authoritative sources with no room for free generation.70% similarUnverifiedThe reliable defense against prompt injection is architectural least-privilege isolation: physically separating the steps that process untrusted content from the steps that have tool permissions, and adding a final human confirmation.70% similar
