Which approach can be used to enforce security policies on employees’ personal devices accessing corporate networks?

The BYOD (Bring Your Own Device) policy is designed specifically to manage and secure personal devices that employees use to access corporate networks. This policy helps organizations set clear rules and guidelines for the usage of personal devices within the workplace, establishing who is responsible for security and how data should be handled.

With a BYOD policy in place, companies can enforce security measures such as requiring the installation of mobile device management (MDM) software, enforcing password protection, and ensuring that devices are kept up to date with security patches. This allows the organization to mitigate risks associated with employees using their own devices, which could otherwise lead to data breaches or unauthorized access to sensitive information.

The other options, while related to security and usage of resources, do not specifically target the unique considerations of personal devices in the workplace in the same way that a BYOD policy does. Data retention policies focus on how long data should be stored, acceptable use policies govern general usage of company resources, and incident response policies deal with how to respond to security incidents. None of these directly address the potential security challenges posed by employees' personal devices accessing the corporate network.
