What is considered the best practice for handling personal cellphones accessing company data?

• A. Ban all personal devices from the network
• B. Conduct real-time monitoring of the phone's activity and usage
• C. Ignore device activity to reduce overhead
• D. Share device credentials with IT

Answer: (B)

This question tests how organizations manage security when personal devices access company data. Conducting real-time monitoring of the phone’s activity and usage is the best practice because it provides ongoing visibility and enforcement across endpoints without shutting down mobility. With monitoring (often implemented via mobile device management), the company can enforce security policies—such as encryption, screen locks, up-to-date OS and apps, and approved apps—while still allowing employees to use their personal devices. It also enables quick detection of risky behavior, jailbroken or rooted devices, data leakage, or unusual access patterns, and supports rapid incident response like revoking access or remote wiping if a device is compromised. Although this approach requires careful privacy and scope policies, it strikes a practical balance between security and user productivity. Bans on all personal devices are too rigid; ignoring device activity leaves gaps in protection; and sharing credentials is a severe security risk, undermining authentication principles.
