From the terminal to the endpoints where data is kept, point of sale systems present a huge attack surface.
FREMONT, CA: Whether a business is implementing a new Point of Sale (POS) system or starting with something new, ask some questions about the company's needs and its capacity to handle potential issues. POS issues are prevalent, especially if one does not analyze the options and changing business demands properly.

POS Systems

Data is communicated through a POS system and its components every time a customer swipes a card or enters a pin. A terminal, as well as keypads, chip readers, inventory tracking systems, printers, barcode scanning, and reporting functionalities, may be included in this advanced system. Unfortunately, older POS systems have insufficient security due to a lack of encryption, making them subject to assaults and other POS issues. Because they do not fulfill PCI compliance, POS terminals are also common attack surfaces. This makes them a tempting target for cybercriminals.
Credit Card Terminal
The primary function of credit card terminals is to process credit card payments. Cards are swiped, and the terminal may connect to a check or gift card system in some circumstances, but they do not perform as many duties as a POS system. While a credit card terminal does not provide the same level of reporting and processing as a POS system, it is critical to ensure that all components engaged in the transaction are compatible with PCI requirements.
Internet Exposure
One open access point is all it takes for hackers to access a complete network of POS machines and systems, allowing malware to be installed.
POS Endpoints
That data is stored somewhere after a transaction, but is it secure? Malicious queries might be inserted into a database to expose or manipulate information. Malware that gains access through one of the points listed above and then scrapes a system for unencrypted data causes some of the most typical POS issues. If one does a transaction, whether it is at a gas station, a retail store, or a grocery store, they are vulnerable to malware attacks.
