Cybercrime is one of the most dynamically changing criminal phenomena. Cybercriminals adapt quickly to technical and economic changes, act globally and attack wherever it is financially profitable from their point of view. This is also the case with stationary retail. There are numerous examples from the recent past where attacks have led to a shutdown of normal operations. And you never know which retailer the offenders will strike next. It is time to think carefully about the appropriate protective measures. One of these measures is the introduction of a fallback POS system to remain ready to act in the event of an actual attack. Patrick Kruschinski from Snabble shows what needs to be done.
