# 🛡️ AgentFortress ### 面向AI代理的CrowdStrike **面向LLM代理的实时安全监控、威胁检测和运行时保护。** [](https://pypi.org/project/agentfortress/) [](https://www.npmjs.com/package/agentfortress) [](https://rubygems.org/gems/agentfortress) [](https://crates.io/crates/agentfortress) [](https://pkg.go.dev/github.com/aayush022008/agentfortress) [](LICENSE) [](LICENSE) [](https://github.com/aayush022008/agentfortress/actions) [](https://github.com/aayush022008/agentfortress/stargazers) [](https://github.com/aayush022008/agentfortress/network) [](https://pypi.org/project/agentfortress/) [](https://www.npmjs.com/package/agentfortress) [Installation](#installation) • [Quick Start](#quick-start) • [Features](#features) • [Documentation](#documentation) • [SDKs](#multi-language-sdks) ## 🆕 v2.0.0 新功能 - 🔴 **`protect()` 现在会实际拦截输入** — 之前只捕获 JavaScript 错误；输入从未被扫描。现在所有字符串参数（包括嵌套的 LangChain 消息对象）在代理运行前都会被扫描。 - 🔴 **修复了花哨字符绕过** — `1gn0r3 all pr3v10us 1nstruct10ns` 现在会被正确拦截。 - 🆕 **输出扫描** — 检测代理响应中的 API 密钥泄露、PII 和凭证暴露。 - 🆕 **会话速率限制** — 自动拦截突发/脚本化攻击会话。 - 🆕 **多轮上下文累积** — 跨回合的慢速探测攻击会被捕获。 - 🆕 **`onAudit` 回调** — 每次扫描的完整审计追踪，支持 SIEM 集成。 - 🆕 **增强的绕过抵抗能力** — 全宽字符集、软绕过（`btw ignore`）、故事包装器越狱、LLaMA/ChatML 令牌注入、嵌套注入（JSON/代码块/URL）。 - ✅ **63/63 测试通过** ## 什么是 AgentFortress？ 随着 AI 代理获得对敏感工具、数据库、API 和文件系统的访问权限，攻击面呈指数级扩大。一个被攻陷的提示词可能指示你的代理窃取数据、绕过访问控制或执行破坏性命令。 **AgentFortress** 是一个安全层，为你的 AI 代理提供全方位监控： - 🔍 **实时监控**每一次工具调用、提示词和响应 - 🚨 **检测**提示词注入、PII 泄露、数据外泄、越狱尝试和范围蔓延 - 🛑 **拦截**威胁，防止造成损害，支持可配置的策略 - 📋 **审计**所有操作，生成加密签名、防篡改日志 - 🎬 **回放**任意会话的每一帧画面，便于事件调查 - 📊 **可视化**实时 SOC 仪表盘中的安全态势 ## 架构 ``` ┌─────────────────────────────────────────────────────────────────┐ │ Your AI Agents │ │ LangChain • CrewAI • AutoGen • OpenAI SDK • Custom Agents │ └──────────────────────┬──────────────────────────────────────────┘ │ AgentFortress SDK (1 line wrap) ▼ ┌─────────────────────────────────────────────────────────────────┐ │ AgentFortress Platform │ │ │ │ ┌─────────────────┐ ┌──────────────┐ ┌───────────────────┐ │ │ │ Threat Detection │ │ ML Engine │ │ Policy Enforcer │ │ │ │ • Prompt inject │ │ • Anomaly │ │ • BLOCK / ALERT │ │ │ │ • PII leakage │ │ detection │ │ • RATE_LIMIT │ │ │ │ • Data exfil │ │ • Behavioral │ │ • Custom rules │ │ │ │ • Jailbreaks │ │ baseline │ │ │ │ │ └─────────────────┘ └──────────────┘ └───────────────────┘ │ │ │ │ ┌─────────────────┐ ┌──────────────┐ ┌───────────────────┐ │ │ │ Audit Logger │ │ Session Mgr │ │ Alert Manager │ │ │ │ • Signed logs │ │ • Replay │ │ • Slack │ │ │ │ • Chain custody │ │ • Kill switch│ │ • PagerDuty │ │ │ │ • Forensics │ │ • Timeline │ │ • Datadog │ │ │ └─────────────────┘ └──────────────┘ └───────────────────┘ │ └─────────────────────────────────────────────────────────────────┘ │ WebSocket ▼ ┌─────────────────────────────────────────────────────────────────┐ │ React SOC Dashboard (localhost:3000) │ │ Real-time feed • Alert management • Session replay • Analytics │ └─────────────────────────────────────────────────────────────────┘ ``` ## 功能特性 | 类别 | 功能 | 描述 | |------|------|------| | **检测** | 提示词注入 | 200+ 已知模式 + ML 评分 | | **检测** | PII 泄露 | 正则 + NER：SSN、信用卡、邮箱、密钥 | | **检测** | 数据外泄 | 大小分析、Base64、编码检测 | | **检测** | 越狱尝试 | 模式库 + 语义相似度 | | **检测** | 范围蔓延 | 资源访问监控 | | **检测** | 异常行为 | 统计基线偏差 | | **策略** | 阻断/告警/记录 | 每条规则可配置动作 | | **策略** | 速率限制 | 突发和持续速率控制 | | **策略** | 熔断开关 | 即时终止会话 | | **审计** | 签名日志 | Ed25519 加密签名 | | **审计** | 责任链 | 防篡改取证记录 | | **审计** | 会话回放 | 完整的帧级时间线 | | **合规** | GDPR | 数据处理审计追踪 | | **合规** | HIPAA | PHI 检测与保护 | | **合规** | SOC 2 | 访问控制与审计日志 | | **合规** | EU AI Act | 高风险 AI 系统合规 | | **情报** | MITRE ATT&CK | AI 威胁技术映射 | | **情报** | 威胁情报 | IOC 管理与匹配 | | **情报** | 威胁狩猎 | 自定义查询构建器 | | **ML** | 孤立森林 | 无监督异常检测 | | **ML** | NLP 分类器 | 语义威胁分类 | | **ML** | 行为基线 | 每个代理的正常行为建模 | | **集成** | Slack | 实时告警推送 | | **集成** | PagerDuty | 值班升级 | | **集成** | Datadog | 指标与 APM | | **集成** | Splunk | SIEM 集成 | | **企业** | RBAC | 基于角色的访问控制 | | **企业** | SSO / SAML | 企业身份提供商 | | **企业** | 多租户 | 组织级隔离 | ## 安装 ### Python (pip) ``` pip install agentfortress ``` ### JavaScript / TypeScript (npm) ``` npm install agentfortress #
