Content Security Policy - Nginx

[Sathish Kumar]

Hi,

I would like to enable Content Security Policy header on Nginx for our
website to protect from data injection attacks and XSS. Can I add like the
below config?. If anybody hit our URL they will know the allowed domains in
the header.

Is there any other bettery way to do this?

add_header Content-Security-Policy "default-src 'self'; script-src 'self'
'unsafe-inline' 'unsafe-eval' https://ssl.google-analytics.com
https://assets.zendesk.com https://connect.facebook.net; img-src 'self'
https://ssl.google-analytics.com https://s-static.ak.facebook.com
https://assets.zendesk.com; style-src 'self' 'unsafe-inline'
https://fonts.googleapis.com https://assets.zendesk.com; font-src 'self'
https://themes.googleusercontent.com; frame-src https://assets.zendesk.com
https://www.facebook.com https://s-static.ak.facebook.com
https://tautt.zendesk.com; object-src 'none'";
