To protect data on user devices in a BYOD environment, which requirement is not advisable?

In a Bring Your Own Device (BYOD) environment, ensuring the security and protection of data on user devices is critical. Two-person integrity is a security principle that requires two individuals to approve or oversee a process or action to prevent fraud or error. While it is an effective control in highly sensitive environments, applying this principle in a BYOD context may not be practical or necessary.

In a BYOD setting, people typically use their personal devices for work, and expecting two-person integrity would create operational challenges and frustration among users. It would not only complicate everyday tasks but could also hinder productivity, as users would have to wait for approval from another person to access or process the data, which undermines the flexibility and convenience that BYOD aims to provide.

On the other hand, using Data Loss Prevention (DLP) agents, implementing local encryption, and enforcing multifactor authentication are much more aligned with protecting data on user devices. DLP agents help monitor and prevent unauthorized data transfers, local encryption ensures that data remains secure on the device itself, and multifactor authentication adds an additional layer of security to user accounts. These measures are practical and enhance security without interfering with the usability that BYOD policies intend to promote.
