# Hardware / Embedded Interface Security
## ACTION REQUIRED(读完后立刻执行)
1. `NOW`: 确认**物理接触授权**与设备归属
2. `NOW`: ESD/电源安全;默认只读探测
3. `NEXT`: 联合 firmware-pentest 做镜像分析
4. `ACT`: 外壳与调试接口识别 → consoles → 提取
## 适用场景
- UART / JTAG / SWD 调试口发现
- 启动日志、root shell、引导打断
- 配合拆机提取 Flash
- 安全启动/加密 Flash 的可行性评估(非破坏性优先)
## 工作流
```text
□ 拆解授权设备;拍照标注测试点
□ 万用表找 GND/VCC/TX/RX;逻辑电平 1.8/3.3/5V
□ USB-TTL 只读日志;记录波特率
□ JTAG:枚举 IDCODE;评估是否锁定
□ 提取镜像 → 交接 firmware-pentest / ghidra
```
## 工具链
| 工具 | 用途 |
|------|------|
| USB-TTL / logic analyzer | UART |
| J-Link / CMSIS-DAP | 调试 |
| bus pirate / flipper(实验室) | 多协议 |
| binwalk / flashrom | 提取 |
## 参考
- `references/debug-interface-triage.md`
- `../firmware-pentest/` `../ot-ics/`
## 路由上下文
**上游**: MASTER R34
**MUST NOT**: 未授权拆机/损坏他人设备
## 任务完成自检
- [ ] 是否记录接口电平与引脚图?
- [ ] 镜像是否哈希保全?
- [ ] Checklist?
