+Implementing the Policy Server Framework</title><shortdesc>This example demonstrates the use of the policy server framework.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p> The example shows you how a server checks messages from a client against
+a security policy. It also shows you how to deal with the result of a security
+check. </p>

+server contains a simple counter. It can change the value of the counter.
+It can also write the value of the counter to a file. The server offers the
+following services to a client: </p> <ul>
+<li id="GUID-79AEF61F-24B7-55FC-88F2-73A3CA124597"><p>Increase the value of
+the counter by any number greater than 1. </p> </li>
+<li id="GUID-67736263-0785-558E-8FAA-B73CD05F3511"><p>Decrease the value of
+the counter by any number greater than 1. </p> </li>
+<li id="GUID-A7FE0EFE-EDA3-5394-AA6C-D34FFEBB2CD4"><p>Increase the value of
+the counter by 1. </p> </li>
+<li id="GUID-191ADD33-2EDC-5493-9F3B-F25AE2AF0708"><p>Decrease the value of
+the counter by 1. </p> </li>
+<li id="GUID-3B10E37A-7172-56EC-A6A2-50C3BC84A029"><p>Reset the counter to
+its default value. </p> </li>
+<li id="GUID-305441F7-6797-52C5-92F2-353C45A7260B"><p>Reset the counter to
+the value in the file <filepath>counter.dat</filepath>. </p> </li>
+<li id="GUID-9744CA5A-3D99-57F3-B596-D8145CC66494"><p>Save the counter value
+in the file <filepath>counter.dat</filepath>. </p> </li>
+<li id="GUID-42C92895-BD40-58C3-ABB2-0D3DD40CA78E"><p>Send the current value
+of the counter to a client. </p> </li>
+<li id="GUID-D6FF0681-5DC7-5605-83F2-4C225EF7520B"><p>Create, initialise and
+close a subsession. </p> </li>
+<li id="GUID-78587766-2027-5A3D-BE90-6FBF512DD252"><p>Send the current number
+of open subsessions to a client. </p> </li>
+</ul> <p>The client sends a message to the server to request one of these
+services. The server checks each request against its security policy. If the
+request fails the security check, the request is rejected. </p> <p>The security
+policy has the following rules: </p> <ul>
+<li id="GUID-AF85DEBB-0A7D-5794-912E-9382D31834CE"><p>If a client asks the
+server to increase the counter value by more than 10, the client ‘s SID value
+must be less than or equal to 0x70fffff5. </p> </li>
+<li id="GUID-007E3288-B47F-5E2C-AA3A-E21FE1251B41"><p>If a client asks the
+server to decrease the counter value by more than 10, the client ‘s SID value
+must be less than or equal to 0x70fffff5. </p> </li>
+<li id="GUID-2C3B7481-478F-5248-98D2-423D288D12C6"><p>If a client asks the
+server for the number of open subsessions, the client’s SID value must be
+0x70fffff0. </p> </li>
+<li id="GUID-BBBDAF33-5DC0-5D01-AEAF-89D36C834045"><p>If a client asks the
+server to save the counter value to the file <filepath>counter.dat</filepath>,
+the client must have both <codeph>ReadDeviceData</codeph> and <codeph>WriteDeviceData</codeph> capabilities. </p> </li>

+the client must have both <codeph>ReadDeviceData</codeph> and <codeph>WriteDeviceData</codeph> capabilities. </p> </li>
+</ul> <p>The example application shows how you to code security policies.
+It also shows you the constants and classes that you must define to use the
+policy server framework. </p> </section>
