What would be the PRIMARY concern when designing and coordinating a security assessment for an Automatic Teller Machine (ATM) system?

ATMs contain sensitive hardware components including card readers, PIN pads, and cash dispensers that are vulnerable to physical attacks such as skimming device installation, card trapping, and direct hardware manipulation (jackpotting). A security assessment must prioritize physical access controls-locks, enclosures, tamper-evident seals, and surveillance-because physical compromise can bypass all logical security controls and directly result in financial fraud or theft.

While maintenance scheduling is an operational consideration, it is not a primary security concern during a security assessment, as it does not directly address vulnerabilities that adversaries would exploit to compromise the ATM.

Network connectivity availability is an operational/availability concern; although network security is relevant, the primary security assessment focus for ATMs centers on physical tamper risks rather than network uptime.

Processing delays relate to performance and availability, not to the core security vulnerabilities that a security assessment of an ATM system is designed to identify and mitigate.
