Cybersecurity

Because Digitalization Is Only Intelligent if It Is Secure

Development Processes Certified per IEC 62443-4-1
In many sectors, IT security and cybersecurity are playing a more and more important role. This is especially true of critical infrastructure, failure of which would result in sustained supply bottlenecks or significantly disrupt public safety. Examples include systems in energy, water, wastewater and transport infrastructure industries, along with the financial sector and the food supply chain. In addition to the actual equipment and systems, buildings such as logistics centers and cold storage warehouses also need to be considered.

For many years, machine data was only evaluated and used in the manufacturing facility in which it was generated. Thus, the risk of unauthorized data access was relatively low. Use of classic defense-in-depth measures ensured that machine data was well protected.

WAGO’s PFC100 and PFC200 Controllers encrypt information directly in the controller and subsequently transmit the data to the cloud via IPsec or OpenVPN. This ensures that machine data is optimally protected against unauthorized access.

Step-by-step to the solution:

• Previously: Data remained in the manufacturing hall.
• Digitization: Defense-in-depth carries risks.
• The solution: Data encryption happens in the controller.

Cyber attacks on automation systems and critical infrastructure are increasing. How can companies protect effectively against cyber attacks?

Our white paper “IT Security in Production Facilities – An Introduction for Small and Medium-Sized Enterprises” has answers. Read about how you can achieve optimal protection of your systems with an integrated approach with “defense in depth.”

The core content of the white paper includes:

• Standards that play a role in the area of IT security
• Ten point plan for protection against cyber attacks
• Requirements on future automation systems

Increased networking has triggered rising concerns about IT security. Therefore, machine manufacturers and operators are intensifying their efforts to protect their own machine data.

WAGO’s PFC100 and PFC200 Controllers come with an integrated firewall that protects against unauthorized network access.

The benefits for you:

• Support for all relevant secure data exchange protocols: SNMP v3, SFTP, FTPS, HTTPS and SSH
• Other protocols supported: DHCP, DNS, FTP, TELNET and Modbus TCP/UDP
• Integrated firewall comes standard, with pre-configured rules for configuration of whitelisting/blacklisting or MAC filters
• Option of controller setup according to the requirements stated in the BDEW (Federal Association of Energy and Water Industries) white paper and the BSI-IT (Federal Office for Information Security) security catalog
