Examples

The following example sets the MessageAuthenticationAuditLevel and ServiceAuthorizationAuditLevel properties to one of the AuditLevel values.

public static void Main()
{
    // Get base address from appsettings in configuration.
    Uri baseAddress = new Uri(ConfigurationManager.
        AppSettings["baseAddress"]);

    // Create a ServiceHost for the CalculatorService type
    // and provide the base address.
    using (ServiceHost serviceHost = new
        ServiceHost(typeof(CalculatorService), baseAddress))
    {
        // Create a new auditing behavior and set the log location.
        ServiceSecurityAuditBehavior newAudit =
            new ServiceSecurityAuditBehavior();
        newAudit.AuditLogLocation =
            AuditLogLocation.Application;
        newAudit.MessageAuthenticationAuditLevel =
            AuditLevel.SuccessOrFailure;
        newAudit.ServiceAuthorizationAuditLevel =
            AuditLevel.SuccessOrFailure;
        newAudit.SuppressAuditFailure = false;
        // Remove the old behavior and add the new.
        serviceHost.Description.
            Behaviors.Remove<ServiceSecurityAuditBehavior>();
        serviceHost.Description.Behaviors.Add(newAudit);
        // Open the ServiceHostBase to create listeners
        // and start listening for messages.
        serviceHost.Open();

        // The service can now be accessed.
        Console.WriteLine("The service is ready.");
        Console.WriteLine("Press <ENTER> to terminate service.");
        Console.WriteLine();
        Console.ReadLine();

        // Close the ServiceHostBase to shutdown the service.
        serviceHost.Close();
    }
}

Public Shared Sub Main() 
    ' Get base address from appsettings in configuration.
    Dim baseAddress As New Uri(ConfigurationManager.AppSettings("baseAddress"))
    
    ' Create a ServiceHost for the CalculatorService type 
    ' and provide the base address.
    Dim serviceHost As New ServiceHost(GetType(CalculatorService), baseAddress)
    Try
        ' Create a new auditing behavior and set the log location.
        Dim newAudit As New ServiceSecurityAuditBehavior()
        newAudit.AuditLogLocation = AuditLogLocation.Application
        newAudit.MessageAuthenticationAuditLevel = _
            AuditLevel.SuccessOrFailure
        newAudit.ServiceAuthorizationAuditLevel = _
            AuditLevel.SuccessOrFailure
        newAudit.SuppressAuditFailure = False
        ' Remove the old behavior and add the new.
        serviceHost.Description.Behaviors.Remove(Of ServiceSecurityAuditBehavior)
        serviceHost.Description.Behaviors.Add(newAudit)
        ' Open the ServiceHostBase to create listeners 
        ' and start listening for messages.
        serviceHost.Open()
        
        ' The service can now be accessed.
        Console.WriteLine("The service is ready.")
        Console.WriteLine("Press <ENTER> to terminate service.")
        Console.WriteLine()
        Console.ReadLine()
        
        ' Close the ServiceHostBase to shutdown the service.
        serviceHost.Close()
    Finally
    End Try

End Sub

Remarks

When creating a Windows Communication Foundation (WCF) application that requires authentication and/or authorization of the callers, you can specify that events related to security be recorded for either success, failure, or both. The level of auditing is determined by this enumeration.

The location of the audit log is specified by setting the AuditLogLocation property of the ServiceSecurityAuditBehavior class to one of the AuditLogLocation values.

For more information about auditing, see Auditing.

You can also specify audit behavior using the <serviceSecurityAudit> binding.
