IsardVDI Security concerns

By default IsardVDI in production mode will open some container ports to the public world as they are required (can be modified in isardvdi.cfg)

  • 80/TCP: Redirect HTTP to HTTPS and HTTP CONNECT method to proxy spice clients
  • 443/TCP: Web secure port and HTML5 viewers port
  • 9999/TCP: RDP proxy gateway port to connect RDP clients
  • 443/UDP: Wireguard VPN for client users
  • 4443/UDP: Wireguard VPN for infrastructure hypervisors. Not need to be open in an all-in-one setup.

To apply a base security and complex infrastructure setups to your installation you have some example scripts for Debian 10 at sysadm folder:

  • This is not a security script, it is only the first thing you should do: install docker & docker-compose. Refer to documentation for other installation sample scripts or better go to the latests documentation for your distro at ([]
  • This is a sample script to install and setup fail2ban and manage ports in firewalld instead of letting the default docker open the ports.
