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

  • 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();


Here’s a list of common HTTP headers, and the Mozilla recommended settings for securing web applications.
