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
