Enhancing the safety of industrial networks through integrated security functions

25.02.2011
New components with integrated security functions from the Siemens Division Industry Automation allow companies to enhance the safety of their networks in process automation and production automation.
The new versions of the Simatic NET CP 341-1 Advanced and Simatic NET CP 443-1 Advanced communications processors contain a firewall as well as a VPN function (Virtual Private Network) and therefore establish secure access to controllers of the Simatic S7-300 and S7-400 series. Industrial PCs can also be equipped with a firewall and VPN client by means of the Simatic NET CP 1628 module. The security module Scalance S623 is also new; with an additional DMZ port for service access, as is the UMTS router Scalance M875 for secure access to plant units via the UMTS mobile network.

Under the name of Security Integrated, the Siemens Division Industry Automation is presenting network components that even offer security features, such as access control, in the basic version. This includes the Simatic NET CP 341-1 Advanced and Simatic NET CP 443-1 Advanced communications processors as well as the Simatic NET CP 1628 module and the UMTS router Scalance M875.

Under the name of Security Integrated, the Siemens Division Industry Automation is presenting network components that even offer security features, such as access control, in the basic version. The Simatic NET CP 341-1 Advanced and Simatic NET CP 443-1 Advanced communications processors with extended functional scope also enable connection to the S7-300 or S7-400 controllers via VPN. It is also possible to define more detailed safety settings and access rights via the integrated firewall. In this manner, the communications processors secure access across the entire plant network. The integrated switch also supports secure connection of the lower-level controllers and HMI and I/O devices.

The Security Integrated range also includes the new Simatic NET CP 1628 module for industrial PCs. It supports secure connection of industrial PCs to the network via a VPN and firewall. In this manner, computers equipped with the module can be connected to protected cells. It is also possible to access an industrial PC with an integral CP 1628 using the Softnet Security Client application over the Internet or a company-internal network via remote access.

Two more new products in the security portfolio of the Industry Automation Division are the security module Scalance S623 and the UMTS router Scalance M875. With Scalance S623, the thoroughly revised range of Scalance S modules is supplemented by a variant with a DMZ port (Demilitarized Zone). This port opens up a separate and, if required, restricted access point to the network for service access. A DSL modem can be connected to the DMZ port for service work via remote access. In the case of Scalance M875, this is a UMTS router with integrated security functions. The router is ideal for secure communication to and from distributed automation cells via VPN, such as the supply stations of a water utility company or mobile plants that have to be centrally monitored or controlled from a control center.

Due to the increased use of Ethernet connections penetrating the field level, security issues are gaining in importance in industry. For comprehensive protection of a plant, a variety of different measures must be implemented. These range from the company organization and its guidelines regarding protective measures for PC and control systems through to protection of automation cells by segmenting the network. Siemens follows the cell protection concept and offers – with the modules of the Scalance M and the Scalance S series together with the security communication modules – numerous components for building up protected cells. With the cell protection concept, a plant network is subdivided into protected automation cells within which all devices are able to communicate with each other securely. The individual cells are connected to the overall network protected by a VPN and firewall. Cell protection reduces the susceptibility to failure of the entire production plant and increases its availability.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
