Which of the following is a primary security concern for a company setting up a BYOD program?

Jailbreaking (or rooting for Android devices) is a primary security concern for BYOD programs because it removes security restrictions imposed by the device manufacturer and operating system. This allows users to install unauthorized applications, modify system files, and bypass security controls, making the device more vulnerable to malware and data breaches. It also complicates security policy enforcement and compliance. End of life refers to a device no longer receiving updates, which is a concern but less direct than jailbreaking. Buffer overflow is a software vulnerability, not a direct BYOD program concern. VM escape is a virtualization security issue, not specific to BYOD.
