Instructions
操作步骤
- Identify the target — Determine the file(s) or directory to scan from the user's request.
- Select the ruleset — Choose the appropriate config:
- General security: (recommended default)
--config=auto - OWASP Top 10:
--config=p/owasp-top-ten - Language-specific: ,
--config=p/python,--config=p/javascript, etc.--config=p/java - CI-focused:
--config=p/ci - Secrets:
--config=p/secrets
- General security:
- Run the scan:
bash
semgrep scan --config=auto --json --output=semgrep-results.json <target-path> - Parse the results — Read the JSON output and present findings in this format:
| # | Severity | Rule ID | File:Line | Finding | Remediation |
|---|----------|---------|-----------|---------|-------------|- Summarize — Provide:
- Total files scanned and findings count by severity (ERROR / WARNING / INFO)
- Critical findings first with code context
- Specific remediation steps referencing Semgrep rule documentation
- 确定目标 — 根据用户的需求,确定要扫描的文件或目录。
- 选择规则集 — 选择合适的配置:
- 通用安全扫描:(推荐默认选项)
--config=auto - OWASP Top 10:
--config=p/owasp-top-ten - 特定语言:、
--config=p/python、--config=p/javascript等--config=p/java - CI场景:
--config=p/ci - 敏感信息检测:
--config=p/secrets
- 通用安全扫描:
- 运行扫描:
bash
semgrep scan --config=auto --json --output=semgrep-results.json <target-path> - 解析结果 — 读取JSON输出,并按以下格式呈现发现的问题:
| 序号 | 严重程度 | 规则ID | 文件:行号 | 问题描述 | 修复建议 |
|---|----------|---------|-----------|---------|-------------|- 总结报告 — 提供以下内容:
- 扫描的文件总数,以及按严重程度(ERROR / WARNING / INFO)统计的问题数量
- 优先展示高危问题及代码上下文
- 参考Semgrep规则文档提供具体的修复步骤
