Security Testing Framework

ZeroTrustKerberosLink includes a comprehensive security testing framework to help you validate the security of your deployment. This framework is designed to identify potential vulnerabilities and ensure that security controls are properly implemented.

Framework Overview

The security testing framework provides:

  1. Structured Testing Approach: Organized by vulnerability types
  2. Severity Classification: Prioritization based on risk
  3. Remediation Guidance: Steps to address identified issues
  4. Reporting Capabilities: Detailed reports in multiple formats

Vulnerability Types

The framework tests for the following vulnerability types:

Web Vulnerabilities

  • Cross-Site Scripting (XSS): Tests for reflected, stored, and DOM-based XSS
  • Cross-Site Request Forgery (CSRF): Validates CSRF protection mechanisms
  • SQL Injection: Tests for SQL injection vulnerabilities
  • Command Injection: Validates protection against command injection
  • Path Traversal: Tests for directory traversal vulnerabilities
  • Authentication Bypass: Attempts to bypass authentication controls

Security Headers

  • Content Security Policy: Validates CSP implementation
  • X-XSS-Protection: Checks for proper XSS protection headers
  • X-Content-Type-Options: Verifies content type options header
  • X-Frame-Options: Validates frame options header
  • Strict-Transport-Security: Checks for HSTS implementation
  • Permissions-Policy: Validates permissions policy header

Authentication and Authorization

  • Password Policies: Tests password strength requirements
  • Session Management: Validates session security
  • Access Controls: Tests for proper authorization
  • Multi-Factor Authentication: Validates MFA implementation
  • Account Lockout: Tests account lockout mechanisms

Infrastructure Security

  • TLS Configuration: Validates secure TLS implementation
  • Redis Security: Tests Redis communication security
  • Network Segmentation: Validates network security
  • Docker Security: Tests container security (if applicable)
  • Secrets Management: Validates secure handling of secrets

Running Security Tests

Basic Test Suite

Run the complete test suite:

zerotrustkerberos-cli security-test --all

Testing Specific Vulnerabilities

Test for specific vulnerability types:

# Test for XSS vulnerabilities
zerotrustkerberos-cli security-test --type=xss

# Test security headers
zerotrustkerberos-cli security-test --type=headers

# Test authentication
zerotrustkerberos-cli security-test --type=auth

Configuration Options

Customize the test execution:

# Set test severity level
zerotrustkerberos-cli security-test --severity=high

# Specify output format
zerotrustkerberos-cli security-test --output=json

# Set target URL
zerotrustkerberos-cli security-test --target=https://localhost:8443

Test Reports

The security testing framework generates detailed reports in multiple formats:

JSON Report

{
  "summary": {
    "total_tests": 42,
    "passed": 39,
    "failed": 3,
    "skipped": 0
  },
  "vulnerabilities": [
    {
      "id": "XSS-001",
      "name": "Reflected XSS in Search Parameter",
      "severity": "high",
      "status": "failed",
      "description": "The search parameter is vulnerable to reflected XSS",
      "remediation": "Implement proper output encoding for the search parameter",
      "details": {
        "endpoint": "/search",
        "parameter": "q",
        "payload": "<script>alert(1)</script>"
      }
    }
  ]
}

HTML Report

The HTML report provides a user-friendly interface with:

  • Executive summary
  • Vulnerability details with severity indicators
  • Remediation guidance
  • Test coverage information
  • Interactive filtering and sorting

Text Report

A simple text-based report for command-line usage:

Security Test Report
===================

Summary:
- Total Tests: 42
- Passed: 39
- Failed: 3
- Skipped: 0

Failed Tests:
1. [HIGH] XSS-001: Reflected XSS in Search Parameter
   - Endpoint: /search
   - Parameter: q
   - Remediation: Implement proper output encoding

2. [MEDIUM] AUTH-003: Weak Password Policy
   - Issue: Password policy does not require special characters
   - Remediation: Update password policy to require special characters

3. [LOW] HEADER-002: Missing X-Content-Type-Options Header
   - Remediation: Add "X-Content-Type-Options: nosniff" header

Integrating with CI/CD

The security testing framework can be integrated into your CI/CD pipeline:

# Example GitHub Actions workflow
name: Security Tests

on:
  push:
    branches: [ main ]
  pull_request:
    branches: [ main ]

jobs:
  security_tests:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: Set up environment
      run: |
        docker-compose up -d
        sleep 10  # Wait for services to start
    - name: Run security tests
      run: |
        zerotrustkerberos-cli security-test --all --output=json > security-report.json
    - name: Upload security report
      uses: actions/upload-artifact@v2
      with:
        name: security-report
        path: security-report.json
    - name: Check for high severity issues
      run: |
        if grep -q '"severity":"high","status":"failed"' security-report.json; then
          echo "High severity security issues found!"
          exit 1
        fi

Custom Test Development

You can extend the security testing framework with custom tests:

  1. Create Test Module:
# custom_test.py
from zerotrustkerberos.security_testing import TestCase, Severity

class CustomSecurityTest(TestCase):
    name = "Custom Security Test"
    severity = Severity.MEDIUM

    def run(self):
        # Test implementation
        result = self.http_client.get("/api/endpoint")
        if "vulnerable_pattern" in result.text:
            return self.fail("Vulnerability found in response")
        return self.pass()
  1. Register Test:
from zerotrustkerberos.security_testing import register_test
from custom_test import CustomSecurityTest

register_test(CustomSecurityTest)
  1. Run Custom Test:
zerotrustkerberos-cli security-test --module=custom_test

Best Practices

To get the most out of the security testing framework:

  1. Regular Testing: Run security tests regularly, not just during deployment
  2. Complete Coverage: Test all components and interfaces
  3. Remediate Promptly: Address identified vulnerabilities quickly
  4. Track Progress: Monitor security improvements over time
  5. Combine with Other Tools: Use alongside other security testing tools
  6. Update Test Suite: Keep the test suite updated with new vulnerability types
