1) Tourism is an important part of Germany's economy and culture, with over 240 million nights spent in German hotels in 2011, a 5.4% increase from 2010. 2) Hotels hold significant customer information such as payment details, personal information, travel plans, which makes them a prime target for hackers seeking financial data. 3) To protect customer information, hotels must comply with PCI security standards which require practices like firewalls, encryption, access control, and regular security testing. Proper network segmentation and access restrictions are also important to reduce risk of credit card fraud and data breaches.
