7.19 Certificate management

HTTPS protocol is used for secure communication between the monitor and the service PC
using the Webmin web client. The purpose for using HTTPS protocol is to authenticate the
connected monitor and to protect the privacy and integrity of the exchanged data between the
monitor and the Webmin web client.
Certificate Management is used to configure the Webmin web client with an X.509 certificate
from a trusted certificate authority. The monitor's service interface provides tools to install a
custom certificate and a public key to the monitor, but first you need to use third party tools or
services to generate them.
By factory default, the monitor has a self-signed certificate of the Webmin web client issued by
GE. To improve access security, you can install a certificate issued and signed by a trusted
certificate authority to the monitor. The certificate authority must be recognized and trusted by
the web browsers used to access the service interface.
