Which Bluetooth security mode allows devices to connect without restrictions?

• A. Security Mode 4
• B. Encryption Level 1
• C. Security Mode 1
• D. EAL 4

Answer: (C)

The correct answer is Security Mode 1, which is designed for open connectivity, allowing Bluetooth devices to connect without restrictions. In this mode, authentication and encryption are not required, facilitating easy connections between devices. This mode is primarily useful in environments where convenience is prioritized over security, enabling devices to discover and connect to each other with minimal barriers. In contrast, other options like Security Mode 4 provide a higher level of security by enforcing strong authentication and encryption protocols, making it more challenging for devices to connect without explicit security measures. Encryption Level 1 relates to a basic level of confidentiality but doesn't define a specific mode of operation in Bluetooth security. The term EAL 4 refers to Evaluation Assurance Level 4, which is a standard used in Common Criteria security evaluations and does not directly pertain to Bluetooth security modes. Thus, Security Mode 1 stands out as the mode that provides unrestricted connectivity among Bluetooth devices.
