Security: Is the HTML Web Engine secure?
Security has the highest priority
Measures such as encrypted communication based on security certificates or user authentication contribute to protecting the system.
This is fully based on the zenon Runtime User Management (including Active Directory). You can set user levels in the zenon RT for example, to prevent somebody who is not authorized from getting into the HMI areas.
It is important to note that the Web Engine is not a secure solution per se. It is – for instance – not recommended to ever publish web content directly to the internet. Surrounding (standard IT) security concepts have to be considered.
The Web Engine recommends and sets the IIS to use HTTPS by default – in order to do this a self-signed certificate is created.
