What would be the PRIMARY concern when designing and coordinating a security assessment for an Automatic Teller Machine (ATM) system?
Correct Answer: A
The primary concern when designing and coordinating a security assessment for an Automatic Teller Machine (ATM) system is the availability of the network connection. An ATM system relies on a network connection to communicate with the bank's servers and process the transactions of the customers. If the network connection is disrupted, degraded, or compromised, the ATM system may not be able to function properly, or may expose the customers' data or money to unauthorized access or theft. Therefore, a security assessment for an ATM system should focus on ensuring that the network connection is reliable, resilient, and secure, and that there are backup or alternative solutions in case of network failure.
