Ensure Security Measures for Bring Your Own Device (BYOD)

A.

When considering the adoption of bring your own device (BYOD), the information security manager needs to ensure that security risks are well understood and mitigated. Therefore, the most important consideration is that business leaders have an understanding of security risks.

Option A is the correct answer because business leaders are responsible for setting the strategic direction of the organization and making informed decisions that align with the organization's goals and objectives. Business leaders need to understand the risks associated with BYOD and the impact that it may have on the organization's information security posture.

Option B is also important since it outlines the acceptable use of personal devices on the corporate network. However, the signing of an acceptable use agreement does not necessarily ensure that the user fully understands the risks associated with using their personal device for work purposes.

Option C is a good practice that should be implemented when allowing personal devices on the corporate network. However, security controls alone cannot guarantee the security of the network, especially if the user's device is already compromised.

Option D is also a good practice, but it is not the most important consideration. Testing applications prior to implementation can help identify potential vulnerabilities, but it does not address the risks associated with users accessing corporate data from their personal devices.

In conclusion, the information security manager needs to ensure that business leaders have a clear understanding of the security risks associated with BYOD to make informed decisions about its adoption. Additionally, it is important to have an acceptable use policy in place, apply security controls to each device when joining the network, and test applications before implementation.
