WSE Policy Advisor is a security plug-in for Web Services Enhancements 2.0 for Microsoft .NET (WSE). It can be invoked either from the WSE Configuration Editor or as a stand-alone tool. It examines the policy files that configure WSE, summarizes their security properties, highlights typical security risks, and provides some remedial advice. Ensure you have installed SP2 of WSE 2.0 before attempting to install WSE Policy Advisor.
