UnverifiedThe 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.79% similarUnverifiedAt a time when prompt injection still has no perfect defense, permission isolation is one of the few security controls that can be delivered deterministically.77% similarUnverified智能体可能通过看似合法的操作组合绕过单点检测，或防护规则对新型攻击模式缺乏覆盖76% similarUnverified纵深防御原则要求系统安全性不应依赖于用户的完美操作，每一层工具都应假设上一层可能已被突破并提供独立的安全校验75% similar
