Enable Data Encryption

To ensure data security, it is recommended to enable SSL encryption. Do the following:

1. Under the nginx configuration directory, create a directory that will be used to hold all of the SSL data:

   sudo mkdir /etc/nginx/ssl
   

2. Create the SSL key and certificate files:

   sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/nginx/ssl/my-example-domain.com.key -out /etc/nginx/ssl/my-example-domain.com.crt
   

   You will be asked a few questions about your server in order to embed the information correctly in the certificate. Fill out the prompts appropriately. The most important line is the one that requests the Common Name. You need to enter the domain name or public IP address that you want to be associated with your server. Both of the files you created (my-example-domain.com.key and my-example-domain.com.crt) will be placed in the /etc/nginx/ssl directory.

3. Configure nginx to use SSL. Open the nginx configuration file. Copy the code from the example below into the file.

   sudo vi /etc/nginx/nginx.conf
   
   upstream ffsecurity {
           server 127.0.0.1:8002;
   }
   
   # redirect from http to https version of the site
   server {
           listen 80;
           server_name domain.ru www.domain.ru;
           rewrite ^(.*) https://domain.ru$1 permanent;
           access_log off;
   }
   
   server {
           listen 443 ssl;
   
           ssl_certificate     /etc/nginx/ssl/domain.pem;
           ssl_certificate_key /etc/nginx/ssl/domain.key;
   
           root /var/lib/ffsecurity;
   
           autoindex off;
   
           server_name domain.ru;
   
           location @ffsec {
                   proxy_set_header Host $http_host;
                   proxy_set_header X-Forwarded-For $remote_addr;
                   proxy_set_header X-Forwarded-Proto $scheme;
                   proxy_http_version 1.1;
                   proxy_set_header Upgrade $http_upgrade;
                   proxy_set_header Connection "upgrade";
                   proxy_pass http://ffsecurity;
           }
   
            location /static/ {
           }
           location /uploads/ {
                   add_header 'Access-Control-Allow-Origin' '*';
                   add_header 'Access-Control-Allow-Methods' 'GET';
                   add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,Authorization';
                   add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';
                   add_header 'Access-Control-Max-Age' 2592000;
           }
           location /ui-static/ {
                   alias /usr/share/ffsecurity-ui/ui-static/;
           }
           location /doc/ {
                   alias /opt/ffsecurity/doc/;
           }
           location / {
                   try_files $uri $uri/ @ffsec;
                   client_max_body_size 100m;
                   alias /usr/share/ffsecurity-ui/;
   
           }
   }
   

4. Restart nginx.

   sudo service nginx restart
   

5. Edit the ffsecurity configuration file. In the EXTERNAL_ADDRESS parameter, substitute the http:// prefix with https://.

   sudo vi /etc/ffsecurity/config.py
   
   EXTERNAL_ADDRESS="https://my-example-domain.com"
   

6. If there are running video-worker services in the system, you need to either recreate cameras in the web interface, or change the router_url parameter in relevant video processing jobs, substituting the http:// prefix with https://. This can be done with the following command:

   curl -s localhost:18810/jobs | jq -r '.[]‌‌["id"]' | xargs -I {} curl -X PATCH -d '{"router_url": "https://domain.ru/video-detector/frame"}' http://localhost:18810/job/{}
