Modular Cyber Security Website & CMS Manual

The frontend is built with modular HTML, CSS (Tailwind CSS), and vanilla JavaScript. It is designed to be responsive, accessible, and performant.

Key Features:

• Semantic HTML5 with ARIA attributes for accessibility.
• Responsive layout using Tailwind CSS utility classes.
• Interactive elements enhanced with vanilla JavaScript.
• Consistent color palette and typography for a professional look.
• Placeholder images use https://fakeimg.pl/ with specific dimensions.

Usage Tips:

• Use semantic tags like <main>, <section>, <article>, and <nav>.
• Ensure all interactive elements are keyboard accessible and have focus styles.
• Use Tailwind’s responsive modifiers (e.g., sm:, md:, lg:) to adapt layouts.
• Apply smooth CSS transitions for hover and focus states to improve UX.

The CMS admin interface allows authorized users to manage website content, users, and settings through a modular dashboard.

Features:

• Modular feature system to add or remove CMS capabilities easily.
• Secure login and session management with logout functionality.
• Image upload with validation and preview.
• Data tables with search, sort, and pagination powered by Grid.js.
• Data visualization with ApexCharts for metrics and trends.

Usage Notes:

• Use keyboard navigation and ARIA roles for accessibility.
• Ensure all forms have client-side validation and clear error messages.
• Use local storage to save user preferences like theme or table settings.
• Implement loading states and feedback for asynchronous operations.

To add a new frontend page, follow these steps:

1. Create the HTML file: Add a new file under src/frontend/pages/ with semantic structure and Tailwind classes.
2. Include necessary components: Reuse components from src/frontend/components/ for consistency.
3. Add styles: Use Tailwind utility classes or extend styles in src/frontend/styles/ if needed.
4. Link scripts: Add any required JavaScript for interactivity, ensuring accessibility and responsiveness.
5. Update navigation: Add links to the new page in the site’s navigation menus.
6. Test: Verify the page on multiple devices and browsers for layout, accessibility, and performance.

Example snippet for a new page header:

<header class="bg-primary-600 text-white p-6 rounded-b-lg shadow">
  <h1 class="text-4xl font-bold">New Page Title</h1>
  <nav aria-label="Breadcrumb">
    <ol class="flex space-x-2 text-sm">
      <li><a href="/" class="hover:underline">Home</a></li>
      <li><span>/</span></li>
      <li aria-current="page" class="font-semibold">New Page</li>
    </ol>
  </nav>
</header>
        

The CMS is designed to be modular. To add a new feature:

1. Create a new feature module: Add a folder under src/cms/features/ with the feature’s frontend and backend code.
2. Develop frontend UI: Build the admin interface components using Tailwind CSS and vanilla JS.
3. Implement backend logic: Add API routes, controllers, and models in the server/ directory.
4. Integrate with CMS dashboard: Register the feature in the CMS admin navigation and load it dynamically.
5. Secure the feature: Apply authentication and authorization middleware to protect feature routes.
6. Test thoroughly: Validate functionality, security, and performance.

Example: Registering a new feature in CMS navigation

// src/cms/admin/navigation.js
const cmsFeatures = [
  { id: 'dashboard', label: 'Dashboard', icon: 'fa-tachometer-alt', path: '/admin/dashboard' },
  { id: 'users', label: 'User Management', icon: 'fa-users', path: '/admin/users' },
  { id: 'newFeature', label: 'New Feature', icon: 'fa-cogs', path: '/admin/new-feature' } // Added feature
];

// Render navigation dynamically
function renderNavigation(container) {
  container.innerHTML = '';
  cmsFeatures.forEach(feature => {
    const link = document.createElement('a');
    link.href = feature.path;
    link.className = 'flex items-center space-x-2 p-2 rounded hover:bg-primary-500 hover:text-white transition';
    link.setAttribute('role', 'menuitem');
    link.innerHTML = `${feature.label}`;
    container.appendChild(link);
  });
}
        

Protecting sensitive pages is critical for security. Use authentication and authorization to restrict access.

Best Practices:

• Use secure session management with HTTP-only cookies or tokens.
• Apply middleware on backend routes to verify user identity and roles.
• Redirect unauthorized users to login or error pages.
• On frontend, conditionally render content based on user permissions.
• Use HTTPS and secure headers to protect data in transit.

Example: Express middleware for authentication

// server/middleware/auth.js
function ensureAuthenticated(req, res, next) {
  if (req.isAuthenticated && req.isAuthenticated()) {
    return next();
  }
  res.status(401).json({ error: 'Unauthorized' });
}

module.exports = ensureAuthenticated;
        

The CMS supports image uploads with validation and preview to ensure security and usability.

Key Points:

• Validate file type and size on client and server sides.
• Use secure storage locations and sanitize filenames.
• Provide image preview before upload.
• Use asynchronous upload with progress indicators.
• Restrict upload access to authorized users only.

Example: Client-side image preview

// HTML:
// <input type="file" id="imageUpload" accept="image/*" aria-label="Upload image">
// <img id="imagePreview" alt="Image preview" class="mt-4 max-w-xs rounded-lg shadow">

document.getElementById('imageUpload').addEventListener('change', function(event) {
  const file = event.target.files[0];
  if (file && file.type.startsWith('image/')) {
    const reader = new FileReader();
    reader.onload = e => {
      const preview = document.getElementById('imagePreview');
      preview.src = e.target.result;
      preview.alt = file.name;
    };
    reader.readAsDataURL(file);
  }
});
        

Implementing a secure logout mechanism is essential to protect user sessions.

Implementation Notes:

• Invalidate the user session or token on the server.
• Clear authentication cookies or local storage tokens on the client.
• Redirect users to the login or homepage after logout.
• Provide a visible and accessible logout button in the UI.

Example: Logout button with event handler

// HTML:
// <button id="logoutBtn" class="px-4 py-2 bg-primary-600 hover:bg-primary-700 text-white rounded-md transition">
//   <i class="fas fa-sign-out-alt mr-2"></i>Logout
// </button>

document.getElementById('logoutBtn').addEventListener('click', () => {
  fetch('/api/logout', { method: 'POST', credentials: 'include' })
    .then(response => {
      if (response.ok) {
        localStorage.clear();
        window.location.href = '/login';
      } else {
        alert('Logout failed. Please try again.');
      }
    })
    .catch(() => alert('Network error during logout.'));
});
        

Follow these tips to maintain high code quality and security:

• Use version control: Commit changes frequently with clear messages.
• Write modular code: Keep components and features isolated and reusable.
• Document your code: Use comments and maintain updated README files.
• Test thoroughly: Write unit and integration tests for critical features.
• Follow security best practices: Sanitize inputs, use HTTPS, and keep dependencies updated.
• Use local storage wisely: Store only non-sensitive preferences and clear on logout.
• Optimize performance: Minimize assets, lazy load images, and use caching.
• Accessibility matters: Test with screen readers and keyboard navigation.
• Use Tailwind CSS utilities: Avoid inline styles and keep styling consistent.
• Leverage Grid.js and ApexCharts: For interactive tables and data visualization.
