KAIROS is delivered as a Docker container.
Port 443 is exposed within the container.
The port "443" is mandatory. When the KAIROS container is created within docker, this port is forwarded to an other port of the physical machine (it can be the same but it can be different.
The physical machine must be accessible through https in the customer network.
The KAIROS user has nothing to install on his laptop. The requirement for him is to use a recent browser (Firefox, Chrome, IE, ... ) supporting HTML5.
The default certificate delivered by GDSC is a self-signed certificate. Normally, this certificate should be changed by the administrator of the physical system supporting the KAIROS container. It should be replaced by a valid certificate in the customer organisation.
