C# 构建SAST（静态应用安全测试）和DAST（动态应用安全测试）
以下一段C#代码展示如何构建一个基础的SAST静态应用安全测试和DAST动态应用安全测试辅助分析工作流框架。示例整合了文件扫描、HTTP请求模拟和结果分析功能。基础框架代码using System; using System.IO; using System.Net.Http; using System.Threading.Tasks; using Newtonsoft.Json; // SAST扫描模块 public class SastScanner { public void ScanDirectory(string directoryPath) { var files Directory.GetFiles(directoryPath, *.cs, SearchOption.AllDirectories); foreach (var file in files) { string content File.ReadAllText(file); if (content.Contains(SqlCommand() !content.Contains(SqlParameter)) { Console.WriteLine($SAST警报: {file} 发现潜在的SQL注入风险); } } } } // DAST扫描模块 public class DastScanner { private readonly HttpClient _httpClient new HttpClient(); public async Task TestEndpoint(string url) { try { var response await _httpClient.GetAsync(url OR 11--); if (response.IsSuccessStatusCode) { Console.WriteLine($DAST警报: {url} 可能存在SQL注入漏洞); } } catch (Exception ex) { Console.WriteLine($DAST错误: {ex.Message}); } } } // 结果分析模块 public class AnalysisResult { public string ToolType { get; set; } public string Vulnerability { get; set; } public string Location { get; set; } } // 主工作流 public class SecurityWorkflow { public async Task Run(string codePath, string[] targetUrls) { var sast new SastScanner(); sast.ScanDirectory(codePath); var dast new DastScanner(); foreach (var url in targetUrls) { await dast.TestEndpoint(url); } } } // 使用示例 class Program { static async Task Main(string[] args) { var workflow new SecurityWorkflow(); await workflow.Run( C:\Projects\TargetApp, new[] { https://example.com/login, https://example.com/search } ); } }扩展功能建议增强SAST功能集成Roslyn分析器进行语法树解析添加正则表达式匹配常见漏洞模式如硬编码密码、XXE等支持自定义规则配置文件增强DAST功能实现OWASP ZAP的API集成添加Cookie身份验证支持构建自动化爬虫识别应用端点结果处理public class ReportGenerator { public void GenerateJsonReport(ListAnalysisResult results) { File.WriteAllText(report.json, JsonConvert.SerializeObject(results, Formatting.Indented)); } }注意事项实际生产环境需考虑异步任务并行化如Parallel.ForEach建议使用成熟的扫描工具如SonarQube、Burp Suite替代部分自定义逻辑动态测试可能触发目标系统防护机制需谨慎配置测试频率
