1 Introduction
The Siemens Scalance S 613 is a security module which protects the
communication between automation networks. It provides authentication, data
integrity and confidentiality and protects against data theft and data manipulation.
In automation engineering more and more components are being connected. The
connection with the Office IT world offers possibilities to use known technologies
from the office field for automation networks which arises threats by attacks from
the external network. The protection of the automation networks is necessary in
order to be resistant against malicious attacks from the external network. Figure 1
clarifies this circumstance.
Unlike the office-world, where standardized schemes such as SSL, TLS, and IPsec
are applied, there are no standards providing data security of automation networks
yet. The analyzed security module protects individual components and entire
networks against data theft and manipulation by implementing a firewall and a
virtual private network (VPN).
