+Security Settings</title><shortdesc>Describes the platform security setting in the variant project
+header file</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p> This setting can be useful if you port Symbian platform from
+a version previous to 9.1. </p>
+<p>A number of <xref href="GUID-3DD52BA7-2EB9-52D4-9BF0-A0A4A2B6BD54.dita">global
+platform security configuration settings</xref> apply when you build a ROM
+image. By default, the settings are ON and no capabilities are specified for
+removal. </p>
+<p>If you change the settings and specify capabilities for removal, you must
+first define the macro <codeph>__PLATSEC_UNLOCKED__</codeph> in the <filepath>variant.mmh</filepath> file
+of your target device and rebuild the kernel. In the template port, you can
+find this file in <filepath>...\template\template_variant\variant.mmh</filepath>. </p>
+<p>Define the macro: </p>
+<codeblock id="GUID-6B0A01E8-CC83-5041-A3F9-043ABA9EA528" xml:space="preserve">#define __PLATSEC_UNLOCKED__</codeblock>
+<p>If you do not define this macro, changes to the settings when you build
+a ROM image are ignored. </p>
+<p>Use of this macro can be good for migration, but remove the macro and rebuild
+the kernel on production devices. </p>
