What happens to the IP addresses during surveys?
IQSN is a high-performance (extremely powerful), fail-safe platform
for conducting online interviews. To ensure this, all inquiries are distributed to many
individual computers via powerful load balancers (load balancers, reverse proxy), which
then ultimately answer the request. For reasons of infrastructure, these exchanges are
made via layer 7 (application layer: forms the interface between the actual application
and the communication system). This means: for technical reasons, the requesting IP address
is always a load balancer. In the log files * of our iqsn web server, we only ever save the
IP address of the intermediary load balancer. These devices, in turn, do not save any IP
addresses and only keep a log file ** for error states, because it is not the task of these
devices to keep logs, but rather to send requests to free computers as quickly as possible.
That is the reason why we at IfaD do not store any IP addresses and therefore no personal data.
* A log file is a file in which IT systems enter and record events. The file should help to
understand certain processes and can be used, for example, for problem analysis or the
reconstruction of transactions. ** A log file contains the automatically kept protocol of
all or certain actions of processes on a computer system.
