Security system of POS-network

The volume of non-cash payments increases every year. Accordingly, the number of POS devices and operations for their use and maintenance is growing. The electronic payment system is a complex structure with many different subsystems and elements distributed over a large territory and requiring significant resources to support their functional state. Fraud in the field of electronic payments is becoming an increasingly serious problem due to the growth of non-cash payments and the emergence of new threats and methods of unauthorized access to information in POS networks. Information protection in the process of making payment transactions requires tighter control and identification of threats in the online mode. The speed of detecting and responding to cyber threats depends on whether the system can prevent critical information from leaking. In an adverse case losses from a fraudulent attack grow exponentially over time.The work studies the existing technologies for implementing the system of security control over functioning of POS networks in real time and analyzes them in detail. Besides, the concept of the system of monitoring and analysis of threats in POS networks is given, and its architecture is offered.
