Security Best Practices for Laravel Applications

Security Best Practices for Laravel Applications

Protect your Laravel blog from common security vulnerabilities with these essential practices.

Authentication & Authorization

1. Strong Password Policies

// In User model
protected static function boot()
{
    parent::boot();
    
    static::creating(function ($user) {
        $user->password = Hash::make($user->password);
    });
}

2. Role-Based Access Control

// Check permissions
if (auth()->user()->can('edit', $post)) {
    // Allow editing
}

Input Validation

Always validate user input:

public function store(Request $request)
{
    $validated = $request->validate([
        'title' => 'required|string|max:255',
        'content' => 'required|string',
        'category_id' => 'required|exists:categories,id'
    ]);
}

SQL Injection Prevention

Laravel's Eloquent ORM automatically prevents SQL injection, but be careful with raw queries:

// Safe
$posts = Post::where('category_id', $categoryId)->get();

// Also safe
$posts = DB::select('SELECT * FROM posts WHERE category_id = ?', [$categoryId]);

XSS Protection

Laravel automatically escapes output in Blade templates, but be careful with {!! !!} tags:

{{ $post->title }}


{!! $post->content !!}
