# Catatan Seekor: Security Testing

> **"Security testing is not about finding vulnerabilities, it's about preventing them"**

## 📚 Overview

Security Testing adalah proses sistematis untuk mengidentifikasi kerentanan keamanan dalam aplikasi, sistem, atau infrastruktur. Ini mencakup berbagai metode testing untuk memastikan bahwa aplikasi aman dari ancaman cyber.

## 🎯 Learning Objectives

* Memahami berbagai jenis security testing
* Menerapkan automated dan manual security testing
* Menggunakan tools dan frameworks security testing
* Melakukan penetration testing dan vulnerability assessment

### **Automated Vulnerability Scan (Python)**

```python
import requests
import json
from urllib.parse import urljoin

class SecurityScanner:
    def __init__(self, target_url):
        self.target_url = target_url
        self.vulnerabilities = []
    
    def scan_headers(self):
        """Scan for security headers"""
        try:
            response = requests.get(self.target_url)
            headers = response.headers
            
            security_headers = {
                'X-Frame-Options': 'Missing clickjacking protection',
                'X-Content-Type-Options': 'Missing MIME type protection',
                'X-XSS-Protection': 'Missing XSS protection',
                'Strict-Transport-Security': 'Missing HSTS',
                'Content-Security-Policy': 'Missing CSP'
            }
            
            for header, description in security_headers.items():
                if header not in headers:
                    self.vulnerabilities.append({
                        'type': 'Missing Security Header',
                        'header': header,
                        'description': description,

    def scan_ssl(self):
        """Check SSL/TLS configuration"""
        try:
            response = requests.get(self.target_url, verify=True)
            if response.status_code == 200:

            self.vulnerabilities.append({
                'type': 'SSL/TLS Issue',
                'description': 'SSL certificate or configuration problem',
                'severity': 'High'
            })
    
    def generate_report(self):
        """Generate security report"""
        report = {
            'target_url': self.target_url,
            'scan_date': str(datetime.now()),
            'vulnerabilities_found': len(self.vulnerabilities),
            'vulnerabilities': self.vulnerabilities
        }
        
        with open('security_report.json', 'w') as f:
            json.dump(report, f, indent=2)
        
        return report

            if (error.response && error.response.status === 500) {
                this.results.push({
                    payload: payload,
                    vulnerable: true,
                    error: 'Server error (potential SQL injection)'
                });
            }
        }
    }
    
    async runTests() {
        console.log('Starting SQL injection tests...');
        
        for (const payload of this.payloads) {
            await this.testPayload(payload);
            // Add delay to avoid overwhelming the server
            await new Promise(resolve => setTimeout(resolve, 1000));
        }
        
        return this.results;
    }
    
    generateReport() {
        const vulnerableCount = this.results.filter(r => r.vulnerable).length;
        
        console.log(`\n=== SQL Injection Test Report ===`);
        console.log(`Target: ${this.targetUrl}`);
        console.log(`Payloads tested: ${this.payloads.length}`);
        console.log(`Vulnerable payloads: ${vulnerableCount}`);
        
        if (vulnerableCount > 0) {
            console.log('\nVulnerable payloads:');
            this.results
                .filter(r => r.vulnerable)
                .forEach(r => console.log(`- ${r.payload}`));
        }
        
        return this.results;
