Security
In the Bluetooth Neighborhood Properties – Security dialog box, you can make a number of decisions concerning the security of your local device. To open this dialog box:
- On the Bluetooth menu, click Bluetooth Neighborhood Properties.
- Click the tab Security.
- Security Mode can be set to either No Security or Link level security.
If a device has selected link level security, no remote device can connect to it without bonding (see “Bonding”. ) Furthermore, only when you have selected link level security can you use encryption (see below).
- Encryption Mode can be enabled or disabled. Based on the use of a link key, this feature can only be enabled when link level security has been selected (see above).
If encryption is enabled: When your device is communicating, only the linked devices will be able to understand the data sent between them.
- Connectability Mode refers to whether or not remote devices having discovered your device will be allowed to establish a link to it. In other words, selecting non-connectable mode is a way of ensuring that no remote device can connect to your device.
- Discoverability Mode refers to whether or not other devices will be allowed to discover your device. In other words, selecting non-discoverable mode is a way of preventing remote devices from discovering your device.
The default settings are as shown in the examples (the illustrations) above.
