Secure Communication in Industrial Networks
An approach that covers all levels simultaneously is essential to comprehensively protect industrial facilities both internally and externally; from operational to field level, from access control to copy protection. For this purpose, Siemens uses a strategy that provides defense throughout all levels: "Defense in Depth" is a comprehensive security concept based on plant security, network security, and system integrity. Siemens is guided by the IEC 62443 standard, the leading standard for security in industrial automation.
SCALANCE S Industrial Security Applications
The SCALANCE S Firewall and VPN Appliances protect industrial networks and automation systems by segmenting the network and establishing secure communication channels. As a part of the "Defense in Depth" Cybersecurity concept, SCALANCE S protects devices and networks in discrete manufacturing and in the process industry and helps create a flexible cell protection concept.
SCALANCE M Industrial Routers
A versatile portfolio; wired or wireless: SCALANCE M includes mobile wireless routers and routers for wired communication. The routers have been proven in a variety of applications that require industrial remote access.
Security Communications Processors
With their integrated firewall; to monitor the data flow and VPN, security communications processors protect against data manipulation and espionage. A special benefit of the security communications processors for SIMATIC controllers is the automatic generation of firewall rules when configured using the TIA Portal.
SCALANCE TAP104 for all networks Data Export
The SCALANCE TAP104 unmanaged Industrial Ethernet Test Access Port is ideally suited to exporting message frames in 10/100 Mbps Industrial Ethernet (particularly PROFINET) networks. Exported message frames can be analyzed with the aid of commercially available diagnostics software for the purpose of diagnosing data communication. The SCALANCE TAP104 can be integrated directly between the connection of two active network stations.
Know How the Network is Protected
Siemens wants the network to be secure. Their solution for network security is part of the "Defense in Depth" industrial security concept, which means protecting automation networks against unauthorized access. The main task is to control all interfaces; for example between the office and plant networks; as well as remote maintenance access. To achieve this, Siemens relies on firewalls and, if necessary, they establish a DMZ (demilitarized zone = security-shielded zone). For secure access to production networks, the "Defense in Depth" concept can be enriched by Zero Trust principles. This approach enables Siemens to set up end-to-end, secure OT networks for the user based on professional planning, design, and the implementation of available, high-performance network infrastructures.
Siemens Expert on Network Security
Network security includes the protection of automation networks against unauthorized access by means of network access protection, network segmentation, and encrypted communication.
Power-Flo Technologies is proud to partner with Siemens as they ensure secure communication in industrial networks is paramount for safeguarding operations against evolving cybersecurity threats. Siemens’ “Defense in Depth” strategy, rooted in the IEC 62443 standard, provides a multi-layered approach to plant security, network integrity, and system protection. By integrating advanced solutions like SCALANCE S firewalls, SCALANCE M routers, and security communications processors, Siemens delivers robust, scalable, and flexible defenses tailored to industrial environments. These innovations, coupled with the implementation of Zero Trust principles, enable organizations to establish secure, end-to-end operational technology (OT) networks. With a comprehensive and proactive security framework, Siemens empowers industries to navigate the complexities of modern automation with confidence.
