Backend Security Authorization

Backend Security Authorization

When to use this skill

• Role-based access control
• Permission systems
• Resource authorization
• Policy enforcement

Workflow

• Define roles and permissions
• Check permissions before actions
• Use middleware for routes
• Implement policies
• Deny by default

Instructions

RBAC Structure

<?php

enum Role: string
{
    case ADMIN = 'admin';
    case USER = 'user';
    case GUEST = 'guest';
}

class User extends Entity
{
    public function hasRole(Role $role): bool
    {
        return $this->role === $role->value;
    }

    public function can(string $permission): bool
    {
        return in_array($permission, $this->permissions ?? []);
    }
}

Authorization Filter

<?php

class PermissionFilter implements FilterInterface
{
    public function before(RequestInterface $request, $arguments = null)
    {
        $permission = $arguments[0] ?? null;
        $user = auth()->user();

        if (!$user || !$user->can($permission)) {
            return Services::response()
                ->setJSON(['error' => 'Forbidden'])
                ->setStatusCode(403);
        }
    }
}

Resources

• Check permissions, not roles
• Use filters for route protection
• Deny by default
