A company wants to deploy Bluetooth devices in an environment where security is paramount right from the initial connection. Which Bluetooth security mode should they implement?
A company wants to deploy Bluetooth devices in an environment where security is paramount right from the initial connection. Which Bluetooth security mode should they implement?
- Mode 3, initiating security measures before the connection is established. (correct)
- A custom mode with no authentication or encryption to minimize overhead.
- Mode 1, to allow unrestricted connectivity for ease of use.
- Mode 2, to initiate security measures after the connection is established for efficiency.
A Bluetooth device is configured to automatically accept all incoming connection requests to ensure seamless connectivity. Which of the following is a potential security risk associated with this configuration?
A Bluetooth device is configured to automatically accept all incoming connection requests to ensure seamless connectivity. Which of the following is a potential security risk associated with this configuration?
- Incompatibility with devices using newer Bluetooth standards.
- Increased power consumption due to constant scanning for devices.
- Exposure to unauthorized access and potential malware spread. (correct)
- Reduced data transfer rates due to encryption overhead.
An engineer is tasked with optimizing the power consumption of a Bluetooth-enabled sensor network without compromising security. Which measure strikes the best balance between these two concerns?
An engineer is tasked with optimizing the power consumption of a Bluetooth-enabled sensor network without compromising security. Which measure strikes the best balance between these two concerns?
- Always keep Bluetooth enabled in discoverable mode to minimize connection latency.
- Completely disable Bluetooth when the sensors are not actively transmitting data.
- Use Mode 1 with a strong encryption algorithm to secure the communication channel.
- Enable discovery mode only when necessary for pairing and configure devices to require user approval for connections. (correct)

Study Notes
Bluetooth Security Modes
- Bluetooth has three security levels (modes)
- Mode 1: No security, devices can connect without restriction
- Mode 2: Authentication and encryption, security after connection
- Mode 3: Security measures before connection, most secure
Bluetooth Advantages
- Wireless connectivity, greater mobility
- Ease of deployment
- Simultaneous data and voice transmissions
- Low power consumption, low cost
Bluetooth Disadvantages
- Low data transfer rate
- Limited range
- Vulnerability to malware and unwanted access
- Some vendors choose less secure Mode 1
Enhancing Bluetooth Security
- Turn off Bluetooth when not needed
- Avoid Mode 1 operation
- Enable discovery mode only for trusted devices
- Configure devices to require user approval for connection requests
- Limit the range of devices
- Install anti-virus and firewall software
