Configure NGINX on an Engine - Administrator Guide - Cortex XSIAM - Cortex - Security Operations

Open the following NGINX configuration file with your preferred editor:

/etc/nginx/conf.d/demisto.conf

Use the following configuration template:

Replace DEMISTO_ENGINE with the appropriate hostname.

# Replace DEMISTO_ENGINE with the appropriate hostname. If needed, change port 443 to the port on which the engine is listening.

upstream demisto {
    server DEMISTO_ENGINE:443;
}

# Uncomment to redirect http to https (optional)
# server {
#     listen 80;
#     return 301 https://$host$request_uri;
# }

server {
   # Change the port if you want NGINX to listen on a different port
    listen 443;
    
    ssl_certificate           /etc/nginx/cert.crt;
    ssl_certificate_key       /etc/nginx/cert.key;

    ssl on;
    ssl_session_cache  builtin:1000  shared:SSL:10m;
    ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
    ssl_prefer_server_ciphers on;

    location / {

      proxy_set_header        Host $host;
      proxy_set_header        X-Real-IP $remote_addr;
      proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header        X-Forwarded-Proto $scheme;

      proxy_pass          https://demisto;
      proxy_read_timeout  90;
    }

    location ~ ^/(websocket|d1ws|d2ws) {
        proxy_pass https://demisto;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
        proxy_set_header Origin "";
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

Restart the NGINX server, by typing the following command:

sudo service nginx restart

Verify you can access the engine by browsing to the NGINX server host.
