Which of the following is the GREATEST risk to a company by allowing employees to physically bring their personal smartphones to work?

Personal smartphones have high-resolution cameras, allowing employees to easily capture and exfiltrate proprietary information, such as documents or equipment, from restricted areas without being detected by network-based Data Loss Prevention (DLP) solutions. This bypass of digital security measures for physical data exfiltration represents a significant and immediate risk to intellectual property and trade secrets.

Installing soft token software is a security measure designed to enhance authentication, not an inherent risk, and does not directly facilitate data loss or compromise company systems by itself.

While true that automated patch management is challenging for personal devices, this is primarily an operational and compliance risk, not the greatest or most direct risk for immediate data exfiltration or intellectual property theft compared to active photography.

Increasing the attack surface is a general security concern due to more devices, but it is less specific and potentially less immediate than the direct, intentional exfiltration of sensitive visual data via smartphone cameras, which poses a substantial and immediate data loss risk.
