Overview

Security testing identifies vulnerabilities, weaknesses, and threats in applications to ensure data protection, prevent unauthorized access, and maintain system integrity. It combines automated scanning (SAST, DAST) with manual penetration testing and code review.

When to Use

• Testing for OWASP Top 10 vulnerabilities
• Scanning dependencies for known vulnerabilities
• Testing authentication and authorization
• Validating input sanitization
• Testing API security
• Checking for sensitive data exposure
• Validating security headers
• Testing session management

Quick Start

Minimal working example:

# security_scan.py
from zapv2 import ZAPv2
import time

class SecurityScanner:
    def __init__(self, target_url, api_key=None):
        self.zap = ZAPv2(apikey=api_key, proxies={
            'http': 'http://localhost:8080',
            'https': 'http://localhost:8080'
        })
        self.target = target_url

    def scan(self):
        """Run full security scan."""
        print(f"Scanning {self.target}...")

        # Spider the application
        print("Spidering...")
        scan_id = self.zap.spider.scan(self.target)
        while int(self.zap.spider.status(scan_id)) < 100:
            time.sleep(2)
            print(f"Spider progress: {self.zap.spider.status(scan_id)}%")

        # Active scan
        print("Running active scan...")
// ... (see reference guides for full implementation)

Best Practices

✅ DO

• Run security scans in CI/CD
• Test with real attack vectors
• Scan dependencies regularly
• Use security headers
• Implement rate limiting
• Validate and sanitize all input
• Use parameterized queries
• Test authentication/authorization thoroughly

❌ DON'T

• Store secrets in code
• Trust user input
• Expose detailed error messages
• Skip dependency updates
• Use default credentials
• Ignore security warnings
• Test only happy paths
• Commit sensitive data
