You can set the SYS server's transfer protocol to define the access mode for the SYS (via Web Client, Control Client, or Mobile Client) as HTTP or HTTPS. The HTTPS protocol provides higher data security. For system with distributed deployment License, you can also enable encrypted transmission to encrypt the data transmission between Application Data Server and System Management Server, thus enhancing the system security.

1. Click System > Security > Transfer Protocol.
2. In the Clients and SYS Transfer field, select HTTP or HTTPS as the transfer protocol between the clients (Web Client, Control Client, and Mobile Client) and the SYS servers.
3. If you select HTTPS, you are required to set the certificate. You can use the system provided certificate, or select New Certificate and click to select a new certificate file.
   Note:

   • The new certificate should be in PEM format.

   • The public key and private key should be in the same certificate file.

4. Optional: Check Encrypted Transmission to encrypt the data transmission between Application Data Server and System Management Server.
   Note:

   This field will show when the system's License support server distributed deployment.

5. Click Save.

   • The SYS server will reboot automatically after changing the clients and SYS server transmission settings.

   • All the users logged in will be forced logout during reboot. The reboot takes about one minute and after that, the users can login again.
