Security Header Middleware

The SecurityHeaderMiddleware layer allows you to apply security related headers to your application. Once setup the middleware can apply the following headers to responses:

• X-Content-Type-Options
• X-Download-Options
• X-Frame-Options
• X-Permitted-Cross-Domain-Policies
• Referrer-Policy

This middleware is configured using a fluent interface before it is applied to your application's middleware stack:

use Cake\Http\Middleware\SecurityHeadersMiddleware;

$securityHeaders = new SecurityHeadersMiddleware();
$securityHeaders
    ->setCrossDomainPolicy()
    ->setReferrerPolicy()
    ->setXFrameOptions()
    ->setXssProtection()
    ->noOpen()
    ->noSniff();

$middlewareQueue->add($securityHeaders);
