+<p>Mobile devices support multiple communication methods, which in turn
+sets high requirements for security. A mobile device with various connection
+methods is exposed to a large number of attackers.</p>
+<p>If you are developing a networked application, consider the following
+scenarios and determine how to recover from them:</p>
+<ul>
+<li><p>The end user may lose network connection at any time or may
+not be able to establish a connection at all.</p></li>
+<li><p>A connection may pass over a public network, which may expose
+the data if it is not encrypted during transmission.</p></li>
+<li><p>Peer-to-peer connections are vulnerable to man-in-the-middle
+attacks. To prevent this, use strong authentication and proper ciphering methods.</p>
+</li>
+</ul>
+<p>For details on networking facilities, see the <xref href="http://www.forum.nokia.com/info/sw.nokia.com/id/c4536832-3dd0-45af-94be-1c4289cc3003/Symbian_OS_Overview_To_Networking_v1_0_en.pdf.html" scope="external">Symbian OS: Overview To Networking</xref> on Forum Nokia. For more information
