## 钩子

OpenClaw 通过钩子提供自动保护。

### 可用钩子

1. **user-prompt-submit-hook** - 在提交前验证用户输入 2. **tool-call-hook** - 在执行前验证工具参数

### 安装

```bash cd {baseDir}/hooks ./install-hooks.sh ```

这将钩子安装到 `~/.claude-code/hooks/`。

### 钩子行为

**用户提示提交:** ``` User Input → Security Scan → [ALLOW/WARN/BLOCK] → Submit or Reject ```

**工具调用:** ``` Tool Call → Parameter Validation → [ALLOW/WARN/BLOCK] → Execute or Reject ```

详细的钩子文档请参阅 `{baseDir}/hooks/README.md`。

---

## 性能

- **验证时间:** 20-50 毫秒(目标:<50 毫秒) - **并行模块:** 所有 6 个模块并发运行 - **异步写入:** 数据库操作不阻塞 - **内存使用:** 通常 <50MB - **吞吐量:** 1000+ 次/分钟验证

### 性能调优

**快速路径:** ```yaml sensitivity: permissive # Fewer patterns checked modules: secret_detector: enabled: false # Disable expensive regex scanning ```

**严格路径:** ```yaml sensitivity: paranoid # All patterns active modules: prompt_injection: sensitivity: strict command_validator: sensitivity: paranoid ```

---

## 数据库架构

### 表

1. **security_events** - 所有验证事件 2. **rate_limits** - 每用户速率限制 3. **user_reputation** - 信任评分和信誉 4. **attack_patterns** - 模式匹配频率 5. **notifications_log** - 通知发送状态

### 查询

```bash # View database schema sqlite3 .openclaw-sec.db ".schema"

# Count events by severity sqlite3 .openclaw-sec.db \ "SELECT severity, COUNT(*) FROM security_events GROUP BY severity;"

# Top attacked users sqlite3 .openclaw-sec.db \ "SELECT user_id, COUNT(*) as attacks FROM security_events WHERE action_taken = 'block' GROUP BY user_id ORDER BY attacks DESC LIMIT 10;" ```

---

## 集成示例

### Node.js/TypeScript

```typescript import { SecurityEngine } from 'openclaw-sec'; import { ConfigManager } from 'openclaw-sec'; import { DatabaseManager } from 'openclaw-sec';

// Initialize const config = await ConfigManager.load('.openclaw-sec.yaml'); const db = new DatabaseManager('.openclaw-sec.db'); const engine = new SecurityEngine(config, db);

// Validate input const result = await engine.validate(userInput, { userId: '[email protected]', sessionId: 'session-123', context: { source: 'web-ui' } });

// Check result if (result.action === 'block' || result.action === 'block_notify') { throw new Error('Security violation detected'); }

// Cleanup await engine.stop(); db.close(); ```

### Python(通过 CLI)

```python import subprocess import json

def validate_input(text, user_id): result = subprocess.run( ['openclaw-sec', 'check-all', text, '--user-id', user_id], capture_output=True, text=True )

if result.returncode != 0: raise SecurityError('Input blocked by security validation')

return True ```

### GitHub Actions

```yaml - name: Security Scan run: | openclaw-sec scan-content --file ./user-input.txt if [ $? -ne 0 ]; then echo "Security validation failed" exit 1 fi ```

---

## 故障排除

### 问题:误报

**解决方案:** 调整敏感度或禁用特定模块。

```yaml modules: prompt_injection: sensitivity: medium # Less aggressive ```

### 问题:性能太慢

**解决方案:** 禁用高开销模块或降低敏感度。

```yaml modules: secret_detector: enabled: false # Regex-heavy module sensitivity: permissive ```

### 问题:数据库过大

**解决方案:** 减少保留期并进行压缩。

```bash openclaw-sec db-vacuum ```

```yaml database: retention_days: 30 # Keep only 30 days ```

### 问题:数据库中缺少事件

**检查:** 1. 数据库路径正确 2. 异步队列正在刷新(`await engine.stop()`) 3. 数据库具有写入权限

---

## 最佳实践

### 1. 从中等敏感度开始

```yaml sensitivity: medium ```

然后根据您的环境进行调整。

### 2. 初始时启用所有模块

```yaml modules: prompt_injection: { enabled: true } command_validator: { enabled: true } url_validator: { enabled: true } path_validator: { enabled: true } secret_detector: { enabled: true } content_scanner: { enabled: true } ```

禁用导致问题的模块。

### 3. 定期查看事件

```bash openclaw-sec events --severity HIGH --limit 100 ```

### 4. 监控用户信誉

```bash openclaw-sec reputation <user-id> ```

### 5. 部署前测试

```bash openclaw-sec test ```
