UnverifiedPrompt injection attacks are dangerous threats in Agent scenarios; there is currently no perfect defense solution, and permission minimization is the most effective mitigation strategy.71% similarUnverifiedThe core value of an external policy layer lies in its non-bypassability — even if the agent code is tampered with or subjected to a prompt injection attack, it can still serve as the last line of defense.70% similarUnverifiedA hard upper limit on permissions can serve as the last line of defense against prompt injection attacks, rendering an agent unable to complete malicious operations even if it is manipulated, because it lacks the corresponding permissions.70% similarUnverifiedThe defense-in-depth principle involves deploying multiple independent protective measures at different levels of a system, so that even if an attacker breaches one layer of defense, they still face subsequent layers of obstruction.69% similar
