connectivity</title><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>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.</p>

<section id="GUID-A0FF4E29-CB0F-4752-B3B7-1F5C0D3EA1C8"><title>Bluetooth</title>

<p>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.</p>

<p>For more information, see <xref href="GUID-6CE12919-FF81-5254-BA12-385F589FEA44.dita">Bluetooth

Management Collection</xref>.</p>

<p>Use the Bluetooth Security Manager to set the appropriate security requirements

(authentication, authorization, and encryption) that <i>incoming</i> connections

to the device's Bluetooth services must meet. For more information, see <xref href="GUID-A035B592-F423-5980-8E7E-E726CF24CF3E.dita">Using Bluetooth Security

Manager</xref>.</p>

<p>The Bluetooth stack will not by default enforce any particular Bluetooth

security for <i>outgoing</i> 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 <xref href="GUID-4F0C4B9D-AA42-59C4-900A-7045FEAAF2F4.dita">Using

security on outgoing sockets</xref>.</p>

<section id="GUID-2CE155AD-1FFC-41D2-9778-032EF43B8002"><title>Infrared</title>

<p>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.</p>

<p>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.</p>
