I need some help for NGINX security headers for a 5years old

1) I have this problem i must add to the nginx.conf some security headers like

add_header X-XSS-Protection "1; mode=block";
add_header X-Frame-Options “DENY”;
add_header X-Content-Type-Options nosniff;

I am used to use htaccess to add them but i have nginx running right now

so my question is where i must put the security headers ? In which part ? the place/order matter ? I mean beginning of the nginx.conf , in the middle , on the final etc .

Sorry for the stupid question !

2) I have found this guide , is done correctly ? on the beginning of nginx.conf and without { } ?

(github the person knows what is doing but i wish to double check it, just in case )

    Mine are setup inside the http {} block, but before the server {} blocks.

    These should be in the server {} block for the listen 443 ssl; server only to avoid sending them on http requests.

    They're actually in another file that's included by nginx.conf, but they could go direct into nginx.conf

    Making another file will be nice I think, in case you plan multiple websites on same server in future.

  • Edit - sorry, these should be inside the server {} block for the SSL section only - otherwise you'll be sending them for HTTP requests too.

    Either putting them in the block directly, or including another file is fine. I have a security.conf file which has these in and is included in the server {} block as required - but I also have a smaller single site setup which just uses one large nginx.conf file.

    You can do it apache style and create a site config for each site in /etc/nginx/sites-available and then create a symlink for each "active" site into sites-enabled. Then in your nginx.conf file just add include /etc/nginx/sites-enabled/*;

    In each of the sites own config file, you can then include any specific additional files - such as a file with security headers.

    I usually add these in the server block itself, for every vhost.

        add_header X-Content-Type-Options nosniff;
        add_header X-XSS-Protection "1; mode=block";
        add_header X-Robots-Tag none;
        add_header Content-Security-Policy "frame-ancestors 'self'";
        add_header X-Frame-Options DENY;
        add_header Referrer-Policy same-origin;

  • Something to be aware of, which tripped me up a number of times: add_header declarations are generally inherited from enclosing blocks. E.g., if headers are specified in a server block, they'll propagate to nested location blocks. However, if a nested block has any add_header lines of its own, that wipes out any inherited headers, so you'd have to re-declare them.

    I took to specifying security headers in a little snippet, which gets included in any blocks that need it.
