Security Testing Automation

Overview

Comprehensive security testing automation patterns for continuous security validation, including penetration testing, fuzzing, compliance checks, and automated test generation using Claude Code.

Security Test Suite Generator

// security/test-generator.ts
import { ClaudeSDK } from '@claude/sdk';
 
export class SecurityTestGenerator {
  constructor(private claude: ClaudeSDK) {}
  
  async generateSecurityTestSuite(
    component: string,
    vulnerabilityTypes: string[]
  ): Promise<SecurityTestSuite> {
    const prompt = `
Generate a comprehensive security test suite for:
Component: ${component}
Vulnerability Types: ${vulnerabilityTypes.join(', ')}
 
Include:
1. Unit tests for security controls
2. Integration tests for authentication/authorization
3. Penetration tests for common attacks
4. Fuzzing tests for input validation
5. Performance tests for DoS prevention
    `;
    
    const response = await this.claude.generateCode(prompt);
    
    return {
      unitTests: this.parseUnitTests(response),
      integrationTests: this.parseIntegrationTests(response),
      penetrationTests: this.parsePenetrationTests(response),
      fuzzingTests: this.parseFuzzingTests(response),
      performanceTests: this.parsePerformanceTests(response)
    };
  }
}

Penetration Testing

    penTest = new PenTest(endpoint);
  });

        "1' AND '1' = '1"
      ];
      
      for (const payload of payloads) {
        const response = await penTest.test({
          params: { id: payload }
        });
        
        expect(response.status).not.toBe(500);

        });
        
        expect(response.body).not.toContain(payload);
        expect(response.body).not.toContain('<script>');

      const rateLimited = responses.filter(r => r.status === 429);
      
      expect(rateLimited.length).toBeGreaterThan(0);

Test Runner

// security/test-runner.ts
export class SecurityTestRunner {
