Which statement about device control policies is true in Sophos?

Device control policies in Sophos are designed to enhance security by managing the use of peripheral devices connected to endpoints. The statement that they enable the blocking of unknown devices is accurate, as these policies allow administrators to set rules regarding which devices can connect to the system. This helps prevent unauthorized devices from accessing sensitive information, thereby reducing the risk of data breaches or malware infections.

By evaluating and categorizing devices attempting to connect, Sophos can enforce these rules effectively, ensuring that only trusted and recognized devices are permitted. This functionality is crucial for maintaining the integrity and security of the network. The other options do not accurately represent the capabilities of device control policies; they encompass broader functionalities than just managing user permissions, apply to various device types beyond mobile, and allow for a range of custom configurations based on organizational needs.
