Security Testing Documentation

Overview

This document consolidates security testing procedures, results, and ongoing security validation for the Vertical Farm project. It covers authentication, authorization, input validation, and security vulnerability assessments.

Security Testing Strategy

Testing Scope

Authentication & Authorization: JWT validation, role-based access control
Input Validation: SQL injection, XSS, CSRF protection
API Security: Rate limiting, CORS configuration, endpoint protection
Data Protection: PII handling, encryption at rest and in transit
Infrastructure Security: Container security, environment configuration

Testing Approach

Automated Testing: Integrated into CI/CD pipeline
Manual Testing: Periodic security audits and penetration testing
Dependency Scanning: Regular vulnerability scanning of dependencies
Code Analysis: Static application security testing (SAST)

Testing Procedures

Authentication Testing

JWT Token Validation

# Test JWT token validation
async def test_jwt_token_validation():
    # Test valid token
    valid_token = create_test_jwt({"user_id": "test-user", "exp": future_timestamp})
    response = await client.get("/api/v1/protected", headers={"Authorization": f"Bearer {valid_token}"})
    assert response.status_code == 200

    # Test invalid token
    invalid_token = "invalid.jwt.token"
    response = await client.get("/api/v1/protected", headers={"Authorization": f"Bearer {invalid_token}"})
    assert response.status_code == 401

    # Test expired token
    expired_token = create_test_jwt({"user_id": "test-user", "exp": past_timestamp})
    response = await client.get("/api/v1/protected", headers={"Authorization": f"Bearer {expired_token}"})
    assert response.status_code == 401

Role-Based Access Control

# Test role-based access control
async def test_role_based_access():
    # Admin user should access admin endpoints
    admin_token = create_test_jwt({"user_id": "admin", "role": "admin"})
    response = await client.get("/api/v1/admin/users", headers={"Authorization": f"Bearer {admin_token}"})
    assert response.status_code == 200

    # Regular user should not access admin endpoints
    user_token = create_test_jwt({"user_id": "user", "role": "user"})
    response = await client.get("/api/v1/admin/users", headers={"Authorization": f"Bearer {user_token}"})
    assert response.status_code == 403

Input Validation Testing

SQL Injection Prevention

# Test SQL injection protection
async def test_sql_injection_protection():
    malicious_inputs = [
        "'; DROP TABLE users; --",
        "1' OR '1'='1",
        "admin'/*",
        "1; DELETE FROM users WHERE 1=1; --"
    ]

    for malicious_input in malicious_inputs:
        response = await client.get(f"/api/v1/users?search={malicious_input}")
        # Should return error or empty results, not cause database errors
        assert response.status_code in [400, 422, 200]
        if response.status_code == 200:
            assert "error" not in response.json().get("message", "").lower()

XSS Prevention

# Test XSS protection
async def test_xss_protection():
    xss_payloads = [
        "<script>alert('XSS')</script>",
        "<img src=x onerror=alert('XSS')>",
        "javascript:alert('XSS')",
        "<svg onload=alert('XSS')>"
    ]

    for payload in xss_payloads:
        response = await client.post("/api/v1/farms", json={"name": payload})
        # Should sanitize input or reject malicious content
        if response.status_code == 201:
            created_farm = response.json()
            # Verify payload was sanitized
            assert "<script>" not in created_farm["name"]
            assert "javascript:" not in created_farm["name"]

API Security Testing

Rate Limiting

# Test rate limiting
async def test_rate_limiting():
    # Make multiple rapid requests
    responses = []
    for i in range(100):  # Exceed rate limit
        response = await client.get("/api/v1/farms")
        responses.append(response.status_code)

    # Should eventually receive 429 Too Many Requests
    assert 429 in responses

CORS Configuration

# Test CORS configuration
async def test_cors_configuration():
    # Test preflight request
    response = await client.options("/api/v1/farms", headers={
        "Origin": "https://malicious-site.com",
        "Access-Control-Request-Method": "GET"
    })

    # Should only allow approved origins
    allowed_origins = response.headers.get("Access-Control-Allow-Origin", "")
    assert "malicious-site.com" not in allowed_origins

Data Protection Testing

PII Handling

# Test PII data handling
async def test_pii_data_protection():
    # Create user with sensitive data
    user_data = {
        "email": "test@example.com",
        "password": "sensitive_password",
        "ssn": "123-45-6789"
    }

    response = await client.post("/api/v1/users", json=user_data)
    assert response.status_code == 201

    # Verify sensitive data is not exposed in response
    user_response = response.json()
    assert "password" not in user_response
    assert "ssn" not in user_response

    # Verify data is encrypted in database
    # (Implementation depends on database structure)
