## Definition
多层安全策略叠加,任何单层失效不影响整体安全。在 AI Agent 场景中,专指防止 AI 硬编码密钥、意外泄露隐私的多层防护机制。
## AI Agent 特有风险
AI 会毫无警觉地将 API key 内联写入代码,这是最大安全风险。
## 多层防护模型
1. **预推送钩子**TruffleHog 在 git push 前扫描所有文件
2. **本地 Git 暂存**:先推送到私有 Gitea不直连公开仓库
3. **CI 扫描管道**Woodpecker 等 CI 在合并前执行安全扫描
4. **分支保护**PR required for mainAgent 无法绕过
5. **最小权限**Agent 持有只读权限,写操作需 human review
