ATM Security: Protecting Cash, Data, and Trust
The Automated Teller Machine (ATM) is a vital, yet vulnerable, component of the global financial system. Its security is a constant battle against sophisticated criminal attacks that target both the cash within the machine and the sensitive financial data of customers. ATM security is a multi-layered defense system that addresses threats from the physical, logical (software), and customer awareness standpoints.
I. Common ATM Threats and Modus Operandi
ATM attacks fall into three main categories: physical theft, logical/malware attacks, and fraud that targets the customer's card data.
A. Physical Attacks
These attacks aim to steal the cash by breaching the ATM's safe or removing the entire machine.
