Overview: Secure Remote Access with VPN

  • Entry
  • Associated product(s)
An introduction to IP based remote Networks and to the related product range of Siemens. For the possible configurations of an IP based remote network there is an overview along with the requirements and the link to the configuration description.

The geographical distribution of automation cells increases the demand for telecontrol (remote control) and teleservice (remote maintenance/diagnostics) in a remote network. The comprehensive Remote Networks portfolio from Siemens offers connection to both conventional (dedicated line, telephone) and IP-based infrastructures (e.g. the Internet).

This document focuses on IP-based networks. You can find an overview of the classic dial-up networks in the archive below.
As remote access to the plant is implemented via a public network (e.g., the Internet), protection against data manipulation and spying is particularly important. For this purpose the following modules of the Siemens Security Integrated Portfolio in virtual private networks (VPN) are used:

  • SCALANCE M-800
  • SINEMA Remote Connect
  • CP x43-1 Adv.
  • CP 1x43-1
  • CP 1243-7
  • CP 1243-8 IRC
  • CP 1543SP-1
  • CP 1542SP-1 IRC
  • CP 1628
  • TS Adapter IE Advanced
  • RTU 3000C

Through a combination of different security measures such as firewalls and VPN, the security modules protect individual devices or even entire automation cells against:
  • Data espionage
  • Data manipulation
  • Unwanted access

Structure of the document
The possible configurations of an IP-based remote network are divided into groups. The criterion for this subdivision is the used vpn protocol:

  • VPN with IPsec
  • VPN with OpenVPN
  • VPN with SSTP

In this document you will obtain an introduction to Remote Networks and the related product range of  Siemens. For the possible configurations there is an overview along with the requirements and the link to the configuration description.
