Using HTTP response headers

Version:

To improve the security of your application against client-based attacks, you can use the HTTP response headers that are supported by your browser.

Make sure that you test every custom header that you create for your application. In some situations, custom headers can cause problems with how the application operates.

Pega Platform supports the ability to add custom headers. However, it is important to note that Pega Platform only sends these headers on dynamic content requests and not on static content requests.

You might consider adding the following security headers to your application:

  • X-XSS-Protection – Prevents cross-site scripting. Prevents attackers from injecting client-side scripts into the website that is viewed from the user side.
  • Strict-Transport-Security – Allows a website to tell browsers that they should communicate only by using HTTPS, not HTTP.
  • Content-Security-Policy – Controls the resources that the user agent can load for the website.

For browsers other than Internet Explorer, do not attempt to set a custom X-Frame-Options response header. Instead, the correct security setting approach is to use a Content Security Policy. If you use both X-Frame-Options and content security policy, be sure to test in order to verify that the options function as intended.

For more information, see Content security policies.

  • Creating a custom application header

    You can create a custom application header to improve the security of your application to protect it from client-based attacks. However, use caution when using custom application headers because they might interfere with how the application operates. Be sure to test the application after implementing custom application headers.

  • Testing a custom application header

    To determine whether a custom application header has been correctly applied, you need to test it.
