Which of the following personally-owned computer peripherals is permitted for use with Government-furnished equipment?

The use of a headset with a microphone through a USB port is permitted for use with Government-furnished equipment because these types of peripherals are generally accepted as they enhance communication and productivity while maintaining the necessary security protocols. USB headsets typically adhere to compatibility standards that ensure they do not introduce significant risks to the government systems.

In the context of cybersecurity, devices like headsets usually serve a singular purpose and do not have the capacity to store or transfer sensitive data, which mitigates potential security threats. Additionally, they are regulated under policies that often govern the use of peripheral devices with government computers, helping ensure that they do not compromise security.

Other peripherals, such as Bluetooth mice or external hard drives, can pose higher security risks due to potential vulnerabilities associated with wireless connections and data storage capabilities, which may allow for unauthorized access or data theft. Similarly, smartphone chargers, while seemingly benign, can also create security concerns, such as the risk of data transfer during charging or malware installation. Therefore, the headset stands out as a safe choice among the options provided.
