IT security and IT basic protection
The elements of infrastructure, IT systems, networks, and applications must be discussed under the
aspects of security and appropriate measures need to be developed. Customer, domestic, or industry
guidelines and directives must be observed under all circumstances.
For additional details, see
IT security on installations with Desigo (CM110663) and Practical Guide on IP
Networks in Building Automation and Control Systems
(CM110668).
