Train custom Random Forest model on your dataset from sentiment.ai.static_ml import StaticMLAnalyzer from sklearn.ensemble import RandomForestClassifier import joblib # Prepare your training data # X = feature vectors (24 features per sample) # y = labels (0=benign, 1=malicious) # Train model model = RandomForestClassifier(n_estimators=100, max_depth=20) model.fit(X_train, y_train) # Save model joblib.dump(model, 'models/custom_rf_model.pkl') # Update config # ai.static_ml.model_path: models/custom_rf_model.pkl ``` ### 自定义 LLM 集成 ``` # config/sentinel.yaml ai: behavioral_llm: server_url: "https://api.openai.com/v1" # Or Anthropic, Cohere, etc. model_name: "gpt-4" api_key_env: "OPENAI_API_KEY" #

Solution: Install AI dependencies pip install scikit-learn httpx numpy pandas joblib python -c "import sklearn; print('AI Ready!')" ``` **问题："LLM server not available"** ``` # Solution 1: Start Ollama ollama serve # Solution 2: Check Ollama is running curl http://localhost:11434/api/tags # Solution 3: Pull model ollama pull llama3 # Solution 4: Use different server sentinel config --set ai.behavioral_llm.server_url http://localhost:1234 ``` **问题："Docker not available"** ``` # Solution 1: Install Docker curl -fsSL https://get.docker.com | sh # Solution 2: Start Docker daemon sudo systemctl start docker # Solution 3: Add user to docker group sudo usermod -aG docker $USER newgrp docker # Solution 4: Use native sandbox (less safe) sentinel config --set sandbox.engine native ``` **问题："Analysis timeout"** ``` # Solution 1: Increase timeout sentinel analyze sample.exe --timeout 600 # Solution 2: Change default sentinel config --set analysis.timeout 600 # Solution 3: Disable dynamic (instant) sentinel analyze sample.exe --no-dynamic ``` **问题："Out of memory"** ``` # Solution 1: Reduce parallel workers sentinel analyze /samples --parallel 2 # Instead of 8 # Solution 2: Increase Docker memory sentinel config --set sandbox.memory_limit 4G # Solution 3: Disable screenshots/memory dumps sentinel config --set analysis.enable_screenshots false sentinel config --set analysis.enable_memory_dump false ``` **问题："Permission denied"** ``` # Solution 1: Run with sudo (if required) sudo sentinel analyze sample.exe # Solution 2: Fix file permissions chmod +x sample.exe # Solution 3: Update config sentinel config --set security.require_sudo false ``` 更多问题请参阅 [TROUBLESHOOTING.md](TROUBLESHOOTING.md) ## 🤝 贡献 我们欢迎社区的贡献！ ### 如何贡献 1. **Fork** 本仓库 2. **创建** 功能分支：`git checkout -b feature/amazing-feature` 3. **提交** 更改：`git -m 'Add amazing feature'` 4. **推送** 到分支：`git push origin feature/amazing-feature` 5. **打开** Pull Request ### 贡献指南 - **代码风格**：遵循 PEP 8，使用 Black 格式化工具 - **类型提示**：为所有函数添加类型提示 - **文档字符串**：使用 Google 风格的文档字符串 - **测试**：为新功能编写单元测试 - **文档**：更新 README 和文档 - **提交**：使用约定式提交消息 ### 贡献领域 - 🐛 错误报告和修复 - ✨ 新的检测引擎 - 📊 自定义分析器 - 🌍 国际化 (i18n) - 📝 文档改进 - 🎨 UI/UX 增强 - 🧪 测试覆盖率扩展 - ⚡ 性能优化 - 🤖 AI 模型改进 ## 📄 许可证 **MIT License** - 免费且开源 完整条款请参阅 [LICENSE](LICENSE) 文件。 ## 🙏 致谢 - **scikit-learn** - ML 框架 - **httpx** - 异步 HTTP 客户端 - **Rich** - 终端格式化 - **Click** - CLI 框架 - **Docker** - 容器化 - **pefile** - PE 解析 - **Ollama** - LLM 运行时 - **MITRE ATT&CK** - 威胁框架 ## 📧 联系与支持 - **GitHub Issues**: [报告 Bug](https://github.com/4fqr/sentinel-framework/issues) - **GitHub Discussions**: [提问](https://github.com/4fqr/sentinel-framework/discussions) - **Email**: dev@sentinel-framework.org - **Twitter**: @SentinelFramework ## 🌟 Star 历史 如果 Sentinel 对您的安全工作有帮助，请给仓库 ⭐ 加星！ ## 🎯 路线图 ### ✅ 已完成（当前版本） - AI 集成（静态 ML + 行为 LLM） - 全面测试（100% 通过率） - 精美终端 UI - 7 个检测引擎 - 专业报告 ### 🔄 进行中（2026 年第一季度） - 云沙箱支持（AWS/Azure/GCP） - YARA 规则集成 - 内存取证模块 - Web 仪表板 ### 🔜 计划中（2026 年第二至第三季度） - Android APK 分析 - macOS/Linux 恶意软件支持 - 实时威胁情报源 - 分布式分析集群 - REST API - 插件系统 - 企业功能（SSO、RBAC）
