Usage Example

import { ScanEngine } from "@/lib/scanner/scan-engine";

const config = {
  scanDepth: "comprehensive",
  includeVulnerabilities: true,
  includeMalware: true,
  includePhishing: true,
  includePerformance: false,
  enableAIAnalysis: true,
  enablePenetrationTesting: true,
  timeout: 300,
};

const result = await ScanEngine.executeScan(
  "https://example.com",
  "url",
  config
);

// Export report
import { ExportService } from "@/lib/reporting/export-service";
ExportService.export(result, "pdf");

Testing

All modules are designed to be testable:

  • Unit tests for individual scanners

Performance Considerations

  • Asynchronous scanning operations
  • Progress tracking for long scans
  • Timeout handling
  • Resource cleanup
  • Efficient pattern matching

Compliance

  • OWASP Top 10 2021
  • CWE (Common Weakness Enumeration)
