Electronic Data Transfer via Network Connection 85
Network Security
The network concept given above is designed for usage in a “closed system”- network
on the customer premises. This design concept leads to the following features of the
communication setup
– The FTP-data transfer is not encrypted in order to allow the
network administrator the customer ’s premises to control the network traffic.
– Since the FTP-password and –ID are not encrypted either and could therefore
be recorded, these ID-data are system parameters and have no logical link to the
user-ID data. Therefore, the user-ID data are still protected.
– To ensure the data integrity of the internal data produced by the Sartocheck
®
4
plus Bag tester, the Sartocheck
®
4 plus Filter tester is the communication master.
No remote access is possible on the Sartocheck
®
4 plus system.
– Additionally, a firewall is installed on the Sartocheck
®
4 plus Filter tester to
prevent any remote access via network. The firewall allows the Sartocheck
®
4 plus
to respond to a network “ping”.
13.2 FTP Server Requirements An FTP server program must be installed on at least one PC to facilitate electronic
data transfer. The FTP server program can either be part of your PC’s operating
system or separately installed software. For the configuration of your FTP server,
please refer to the FTP server’s manual.
13.2.1 How to Configure Your The following topics should be considered during the configuration of the FTP server:
FTP Server – Should you create only one or more Sartocheck
®
4 plus Filter tester accounts on
your FTP server? This it depends on how you would like to archive your test data.
If you would like to save all the data in one folder, you should have only one
Sartocheck
®
4 plus account on the FTP server which can be used by all Sartocheck
®
4 plus ’s in the network.
– Should it be allowed to overwrite files on the FTP server? In order to avoid the
accidental deletion of your data, you should activate the overwrite protection on
your FTP server at minimum for the test result folder.
– Different access rights for the different folders? It might be helpful to allow
overwriting or deletion for the SC4 plus program folder or SC4 plus config folder
on the FTP server if you would like to share this files with several other SC4 plus
in the network. Modifications to the files could be carried out on one Sartocheck
®
4 plus and copied afterwards into the FTP folder on the network. Existing older
versions will then be overwritten and the newest version wil be available on the
net work to the other SC4 plus’s.
