English(EN) How to Stop Prompt Injection in AI Agents: Enforced Guardrails, Not Prompts

AI 代理通过外部网关保护操作，绕过模型判断

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-29 21:16

一种新的 AI 代理安全方法提出将执行移至模型本身之外，解决了当前护栏中模型既是目标又是执行者的失败问题。该方法使用受信任的网关来审查代理建议的操作，将通俗易懂的规则编译成 Cedar 策略。该系统确保每个操作都由网关进行检查，网关充当瓶颈，通过使执行独立于代理的判断来防止提示注入。 AI

影响这种方法可以通过使 AI 代理的操作更可预测、更不易受到操纵来显著提高其安全性。

本文如何被排名

Signal score: 26 / 100; Composite score across the factors below. Higher = stronger signal that this story matters right now.
Newsworthiness bucket: Tool; 该项目描述了一种新颖的 AI 安全和安保技术方法，引用了学术论文和特定的策略语言（Cedar）。[lever_c_demoted from research: ic=1 ai=1.0]
Source corroboration: Single-source cluster; Only one publisher covered this so far. Single-source stories can still rank when the publisher is high-authority, but they lack cross-source corroboration.
Topics: safety, product; Editorial topic classification. Feeds into how the story surfaces on /topic/<slug> hub pages and into the per-entity coverage mix.
AI-industry relevance: High; Clearly on-topic for AI-industry coverage.
Story freshness: Breaking (< 6h); Fresh story with cross-source coverage still developing. Ranking may shift as more sources report.
