Local +connectivity

Local connectivity has fewer security issues due to its short range. +However, general rules of communication security apply to local connectivity +as well. This section discusses Bluetooth and infrared.

Bluetooth +

The Bluetooth wireless technology is a short range and low power network +for data and voice communication in any place of the world. The figure below +illustrates the relationships between the different Symbian Bluetooth classes.

For more information, see Bluetooth +Management Collection.

+Bluetooth API +

Use the Bluetooth Security Manager to set the appropriate security requirements +(authentication, authorization, and encryption) that incoming connections +to the device's Bluetooth services must meet. For more information, see Using Bluetooth Security +Manager.

The Bluetooth stack will not by default enforce any particular Bluetooth +security for outgoing socket connections. If the remote device requires +authentication or encryption to connect, it will be handled automatically +by the Bluetooth stack. For more information, see Using +security on outgoing sockets.

Infrared +

Infrared provides a means for short-range communication between devices. +Symbian implements the Infrared Data Association (IrDA) stack for infrared +connections. Infrared connections are handled through general Serial or Socket +Server interfaces.

The IrDA standard does not specify any security features for data transfer, +but since the devices attempting infrared connection are in visual contact, +it is easier to control communication and access to the device. Implement +authentication, authorization, encryption, or any other security features +needed in the application level.
