The Target data breach has many business owners wondering what they can do to prevent malware on their POS systems, but the reality is that not all data breaches are so advanced as the one experienced by the retail giant. Data breaches can occur in a number of ways, so be sure that you aren’t leaving your customer data out for the world to see.
Too Much Information on receipts
Many small businesses have not updated their invoicing or register receipts to show as little customer data as possible. Customer names, addresses, and other sensitive data are often printed on these forms, and if left in the wrong hands, that information could be used to compromise a customer’s bank account or even steal someone’s identity. Be sure to omit as much identifying information as possible to ensure your customers’ privacy.
Once you invest in a POS system or business computer for payment processing, it’s easy to forget about critical updates to your systems. The older the system you use, the more likely it is that someone could hack into it. Be sure that you update your software regularly and install firewalls to keep data more secure.
Leaving a Paper Trail
In the digital age, there isn’t much need for keeping paper files for each of your customers. If you still prefer to do business this way, be sure that you shred old documents as often as possible to limit the amount of sensitive information that is floating around your office. Locking your cabinets and offices and adding a security system will add an extra layer of protection for these documents.
Make sure that your payment processing system, printed receipts, and physical customer files are protected. Not all data breaches occur in the same way that the Target breach did, and you’ll want to be sure that your business is always protected.
