Authentication

Since IP addresses can be falsified (IP spoofing), checking the IP address (of the client access) is not sufficient for reliable authentication. In addition to this, Client PCs may have changing IP addresses. For this reason, the authentication is performed using tried and tested VPN mechanisms.

Data encryption

Secure encryption is necessary to protect data traffic from espionage and manipulation. This means that the data traffic remains incomprehensible to any eavesdropper in the network. To achieve this, the SOFTNET Security Client establishes connections on IPSec based VPN tunnels to other SCALANCE S, SCALANCE M, the S7 Security CPs or the PC-CP 1628.

Performance data

System requirements (please note the descriptions under "Ordering data"):
Windows 7 Professional or Ultimate 32/64-bit
Windows XP Professional (32-bit) + SP3

Configuration

Using the associated configuration tool it is possible to create and manage security rules even without special security knowledge. In the simplest case, only the SCALANCE S modules or SOFTNET Security Clients that will communicate with each other are created and configured. As soon as SOFTNET Security Client knows the programmable controllers to be accessed, communication can be established.
