In order to improve the security of your site against ClickJacking, it is recommended that you add the following header to your site:

  X-Frame-Options: SAMEORIGIN

It is supported by all browsers and prevents an attacker from iframing the content of your site into others.

This article from Mozilla explains it in detail: On the X-Frame-Options Security Header

Enabling this header

You can enable it by modifying your Apache settings or your .htaccess file, and adding the following line to it:

<IfModule mod_headers.c>
  Header always append X-Frame-Options SAMEORIGIN

Or you can enable it automatically on CloudProxy (along with other security headers) by setting "Additional Security Headers " to on. Note that it is enabled by default for all our customers.
