Remarks

Given that most applications are secured based on the network topology in which the Web service resides, WSE 3.0 introduces a scenario-based methodology to secure communication to and from a Web service. That is, instead of piecing security together for an application using multiple low-level security operations, WSE allows you to apply security at a higher level using a prepackaged set of security operations, which are known as security assertions. For common scenarios, WSE provides a set of these security assertions that are called turnkey security assertions. Each of these Turnkey Security Assertions derive directly or indirectly from PolicyAssertion. A developer can also create a custom policy assertion that derives from PolicyAssertion or SecurityPolicyAssertion. For more information about creating a custom policy assertion, see How to: Create a Custom Policy Assertion.

The PolicyAssertion and SecurityPolicyAssertion classes are similar in that they both represent policy assertions, however they have their differences. The SecurityPolicyAssertion class, which derives from the PolicyAssertion class, is for policy assertions that specifically deal with security. For other types of policy assertions that do not apply security to a SOAP message exchange, such as a trace policy assertion, derive a class from the PolicyAssertion class.
