Hello,

there is something that surprises me with the application of security headers in the htaccess.

1) If i scan my website with this site https://securityheaders.com/ to check security headers. I am told that I am missing the following headers:

Content-Security-Policy, X-Frame-Options and X-Content-Type-Options.

In my htaccess file i have this lines :

  • Header always append X-Frame-Options SAMEORIGIN
  • Header set X-Content-Type-Options "nosniff"
  • Header always set Content-Security-Policy "script-src 'none'" (for SVG files)

2) For the tests if i install and activate this plugin HttpHeader

i scan headers with https://securityheaders.com/. In this case the headers are applied and I go green in the tests ...

Can I have an explanation?

Best regards.

When you are using .htaccess code, which is parsed by your web server, to add headers to all requests regardless of whether they go through Joomla or not the headers are not applied.

When you use a PHP plugin which adds the headers with PHP code (and only for the requests that go through Joomla) the headers are applied.

Therefore your web server, which is set up and maintained at the sole responsibility of the host you use to host your site, seems to ignore the Header lines. As a result the problem is something that your host is responsible for.

So, no, we can neither take responsibility nor answer for what a third party company is doing per our Terms of Service and common sense. Please ask this question to your host. I am closing this ticket as out of scope of our support services.
