Laravel 11 brings a multitude of enhancements aimed at making web development more efficient and secure. Here’s a detailed look at the key security features, along with examples to illustrate their use:
1. Advanced Rate Limiting
Laravel 11 introduces advanced rate limiting to help protect your application from abuse. You can set limits on the number of requests a user can make within a certain timeframe.
Example:
php
use Illuminate\Support\Facades\Route;
Route::middleware('throttle:60,1')->group(function () {
Route::get('/api/resource', [ResourceController::class, 'index']);
});
In this example, the throttle middleware limits the /api/resource endpoint to 60 requests per minute.
2. Improved CSRF Protection
CSRF protection has been enhanced in Laravel 11. A unique CSRF token is generated for each user session, preventing unauthorized form submissions.
Example:
html
<form method="POST" action="/submit">
@csrf
<input type="text" name="name">
<button type="submit">Submit</button>
</form>
The @csrf directive generates a hidden input field with a CSRF token, which Laravel validates on form submission.
3. Password Hashing
Laravel 11 continues to use bcrypt for password hashing, ensuring user credentials are secure.
Example:
php
use Illuminate\Support\Facades\Hash;
$user->password = Hash::make('password123');
This example demonstrates how to hash a password before storing it in the database.
4. Content Security Policy (CSP)
Laravel 11 includes built-in support for Content Security Policy (CSP), helping to protect against XSS attacks by restricting the sources from which a webpage can load resources.
Example:
php
use Illuminate\Http\Request;
public function __construct()
{
$this->middleware(function (Request $request, $next) {
$request->headers->set('Content-Security-Policy', "default-src 'self'; img-src 'self'; script-src 'self'");
return $next($request);
});
}
This middleware sets the CSP headers for all responses.
5. SQL Injection Protection
Laravel 11 protects against SQL injection attacks by using prepared statements and parameter binding.
Example:
php
use Illuminate\Support\Facades\DB;
$users = DB::select('SELECT * FROM users WHERE active = ?', [1]);
This query uses parameter binding to prevent SQL injection.
6. Encryption
Laravel 11 provides simple and effective encryption measures to secure sensitive data.
Example:
php
use Illuminate\Support\Facades\Crypt;
$encrypted = Crypt::encryptString('Sensitive data');
$decrypted = Crypt::decryptString($encrypted);
This example shows how to encrypt and decrypt sensitive data using Laravel’s Crypt facade.
7. Health Check Endpoint
A new health check endpoint allows developers to monitor application health and detect potential security issues.
Example:
php
Route::get('/health-check', function () {
return response()->json(['status' => 'ok']);
});
This endpoint returns a JSON response indicating the application status.
8. Secure Configuration and Service Providers
All configuration settings in Laravel 11 are streamlined into .env files, keeping sensitive information secure.
Example:
env
DB_PASSWORD=your_database_password
Sensitive information is stored in the .env file, which should never be committed to version control.
9. Simplified Project Structure
Laravel 11 offers a simplified project structure with fewer preset directories, making it easier to manage and secure your application.
Example:
project/
|-- app/
| |-- Http/
| |-- Models/
|-- config/
|-- routes/
|-- .env
This is an example of the simplified directory structure in Laravel 11.
10. Regular Security Patches
Laravel 11 receives regular security patches, ensuring your application remains secure.
By upgrading to Laravel 11, developers can leverage these advanced security features to build robust and secure web applications confidently.
