Which situation presents the highest risk for large-scale health information breaches?

The situation that presents the highest risk for large-scale health information breaches is laptop theft. Laptops often contain sensitive and personal health information that, if stolen, can potentially lead to unauthorized access and exploitation of that information. When a laptop is taken, it can provide direct access to databases and files that store large quantities of health data, which can then be breach targets for malicious actors.

In contrast, while computer monitors in high-traffic areas and unattended workstations could pose risks for incidental exposure or casual viewing of information, they typically do not lead to the extensive and uncontrolled access that comes with the theft of a laptop, which is often unencrypted and directly used for access to sensitive data. Unlocked rooms may also present a security concern, but the risk is more circumstantial and dependent on what specific items are left unattended within those rooms. Overall, laptop theft is particularly critical due to the combination of mobility, accessibility, and the potential for significant data exposure in a single incident.
