Cyber criminals are systematically attacking systems that store credit card data, including Point-of-Sale and Property Management Systems. The criminal organizations are highly structured and integrated with the world’s organized crime rings. 
Detailed forensic analysis by law enforcement agencies and specialized private-sector security practices, as well as by security departments at major hotel groups around the world, leave little doubt that the attacks on hotels are highly targeted and effective.
Many hoteliers believe they are not vulnerable because they use Point-of-Sale and Property Management Systems that have been validated as conforming to the latest PCI security standards. Unfortunately this is far from the case. Even such validated systems can be vulnerable if the hotel operates them in an unsecured manner. Leading forensics firms agree that the most important security measures are those that keep cyber criminals from getting inside the hotel network in the first place. Once inside, there are many ways for them to steal the data, even if the PMS or POS system itself is secure.
- Eliminate EVERY default password on EVERY machine on your network – server, workstation, router, firewall, and any other device that has a password. The most important machines to check are the ones you think are NOT vulnerable, such as a PC on an engineer’s desk for monitoring building systems, or the PC in the parking garage attendant’s office, or the one in a closet running your keycard system.
- Eliminate holes in remote access to systems inside your network. Remote access by vendors is an essential part of support for many hotel systems. The data thieves know this, and they know how to use it to get inside your network. They know all the default passwords, and they have even been known to steal master customer lists, complete with current passwords, from vendors.
- If you were to store stacks of money in plain sight in an exit stairwell, you would expect to be robbed. Operating without an Internet firewall is just as risky. Yet many hotels, especially smaller ones, don’t have a firewall. If you are connected to the Internet without one, then people you don’t know, from around the world and many with malicious intent, are reaching into your network.
