Siemens' Simatic NET CP 343-1 Advanced and Simatic NET CP 443-1 enhance network security
Siemens Industry Automation announces new versions of its Simatic NET CP 343-1 Advanced and Simatic NET CP 443-1 components with integrated security functions to enable companies to enhance the security of their networks in process automation and production automation. These communications processors contain a firewall, as well as a VPN function (virtual private network), which provides secure access to the Simatic S7-300 and S7-400 controller series. The 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 a 3G cellular network using UMTS.
The Simatic NET CP 343-1 Advanced and Simatic NET CP 443-1 Advanced communications processors with extended functional scope enable connection to the S7-300 or S7-400 controllers via VPN. It is also possible to define more detailed security settings and access rights via the integrated firewall. Through this function, 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.
