Cybersecurity is the topic that all companies are dealing with today. With its "Defense in Depth" as comprehensive protection concept, Siemens provides answers in form of an in-depth defense based on the recommendations of IEC 62443 in industrial automation.
Network security for the protection of automation networks against unauthorized access forms part of the Industrial Security concept. It includes control of all interfaces, e.g. between office and plant networks or remote maintenance access to the Internet, and can be implemented by means of firewalls and the setup of a DMZ (demilitarized zone = zone shielded by enhanced security measures), if necessary. On the basis of professional planning, design, and implementation of available, powerful network infrastructures, it is possible to implement OT networks both consistently and safely.
