How to Secure Your Laravel App (Without Losing Your Mind!)

How to Secure Your Laravel App (Without Losing Your Mind!)

Laravel is an amazing PHP framework that makes web development easier, but let’s be real—if you don’t take security seriously, you’re leaving the door wide open for trouble. Let’s walk through some of the best ways to keep your Laravel app safe from hackers, bots, and other digital gremlins.

1. Keep Laravel and Dependencies Updated

New vulnerabilities pop up all the time, so staying updated is crucial. Laravel’s team regularly releases security patches, and you don’t want to miss out.

Quick update command:

composer update

Also, check Laravel’s official documentation when upgrading between major versions.

2. Lock Down Authentication

Laravel’s authentication system is solid, but a few tweaks can make it even better:

  • Turn on two-factor authentication (2FA).
  • Use Laravel Sanctum or Passport for API authentication.
  • Enforce strong password rules and store passwords securely using bcrypt.

3. Protect Your .env File

Your .env file is like the keys to your house—keep it safe! Here’s what you can do:

  • Never commit it to Git (add it to .gitignore).
  • Store sensitive credentials in a secure vault like Laravel Vault or AWS Secrets Manager.
  • Use proper file permissions (chmod 600 .env).

4. Stop SQL Injection in Its Tracks

Laravel’s Eloquent ORM already helps prevent SQL injection, but you should still avoid raw queries.

❌ Bad (Vulnerable to SQL Injection):

DB::select("SELECT * FROM users WHERE email = '$email'");

✅ Good (Safe and Secure):

DB::select("SELECT * FROM users WHERE email = ?", [$email]);

Or even better:

User::where('email', $email)->first();

5. Block Cross-Site Scripting (XSS)

XSS attacks can turn your site into a hacker’s playground. Here’s how to prevent them:

  • Always use {{ $variable }} instead of {!! $variable !!} in Blade templates.
  • Sanitize user input with Str::of($string)->stripTags();.
  • Add Content Security Policy (CSP) headers.

6. Enable CSRF Protection (Laravel Has Your Back!)

Laravel automatically includes Cross-Site Request Forgery (CSRF) protection. Just make sure to use it:

<form method="POST" action="/submit">
    @csrf
    <input type="text" name="name">
    <button type="submit">Submit</button>
</form>

For APIs, either disable CSRF tokens or use JWT authentication instead.

7. Set Proper File Permissions

A simple mistake in file permissions can expose your entire app. Here’s the safe way to do it:

  • .env file: 600 (chmod 600 .env)
  • storage and bootstrap/cache folders: 755 or 750
  • Never use 777 (seriously, don’t do it!).

8. Force HTTPS (Because HTTP Is So 2000s)

An unencrypted connection is an open invitation for attackers. Redirect everything to HTTPS:

use Illuminate\Support\Facades\URL;

public function boot()
{
    URL::forceScheme('https');
}

Also, set up automatic HTTPS redirection in your server settings.

9. Hide Debugging Info in Production

When APP_DEBUG=true, Laravel might expose sensitive details—bad idea for production! Always set it to false:

APP_DEBUG=false

And while you’re at it, configure proper logging in config/logging.php.

10. Limit Requests to Stop Brute-Force Attacks

Want to stop hackers from spamming login attempts? Use Laravel’s rate limiting:

Route::middleware(['auth', 'throttle:60,1'])->group(function () {
    Route::get('/dashboard', 'DashboardController@index');
});

This limits users to 60 requests per minute.

Final Thoughts

Laravel gives you a great starting point for security, but it’s up to you to take it to the next level. By following these best practices—keeping things updated, locking down authentication, preventing SQL injection and XSS, enforcing HTTPS, and more—you’ll build a much stronger, safer application.
