Bluetooth Security Modes

A Bluetooth device may operate in one of three security modes:

• Security mode 1 No security

• Security mode 2 Service-level enforced security

• Security mode 3 Link-level enforced security

The main difference between modes 2 and 3 is the timing of security procedure initiation. With level 3, the security measures are in place before a L2CAP channel is opened. With mode 2, security measures are initiated with the opening of the channel.

If you see the AUTH and ENCRYPT flags in the output of hciconfig, you are in security mode 3, which is the most secure type of operation.
