Most distributions of NGINX no longer include sites-enabled and sites-available directories. This example installation is based on distribution that does not include these directories, and places the configuration file in the /etc/nginx/conf.d directory. If your installed version of NGINX includes sites-enabled and sites-available directories, consult the NGINX documentation for further guidance.

Save a backup of the default configuration file:

Code Block
sudo mv /etc/nginx/conf.d/default.conf /etc/nginx/conf.d/default.conf.bak

Drop HTTP v1.0 traffic: in the configuration below, we drop HTTP v1.0 traffic - see comment in the configuration. As noted, there is a possible very minor impact if you are building a website that you want to be discoverable on all search engines, but this is unlikely to affect major search engines. We have taken the option to drop HTTP v1.0 traffic because this is very straightforward; the alternative configuration to allow HTTP v1.0 but mitigate specific risks is more complex, and in our opinion, overall a bigger risk to reliably providing the service because it is more prone to being configured incorrectly or having unintended consequences.

Create configuration file for PhixFlow: open editing on a file /etc/nginx/conf.d/phixflow.conf (e.g. with sudo nano /etc/nginx/conf.d/phixflow.conf), and paste in the following, replacing [domain] with your domain, e.g. phixflow.mycompany.com:

Code Block

server {
        listen 80 default_server;
        server_name _;
        return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    listen [::]:443 ssl ipv6only=on;

    server_name [domain];
    
    # Drop all HTTP v1.0 traffic. Only a very small number of legitimate robots now use this, and in most cases PhixFlow installations are not intended to be found via
    # search engines, and even if they are, this is unlikely to have anything other than a very minor effect. We can realistically assume that no user connections will use HTTP v1.0.
    # HTTP v1.0 can be used by malicious actors exploiting weaknesses in the protocol as part of an attack.
    # If we have to re-instate this for some reason, there are migitations - for example, for the case when requests are submitted with HTTP v1.0
    # with no header set, which can lead to exposing the private IP address of this (the reverse proxy) server; make sure, in this case, that we apply these mitigations.
