When it comes to mobile device security, the overlooked and unintended path is usually the best one to an objective. A bring-your-own-device policy for any company brings about a few apparent risks, including IoT device misconfiguration, mixing work and personal activity on the same device, home Wi-Fi security vulnerabilities, and lack of security precautions on the physical device.
