Public Property SecurityMode As System.ServiceModel.BasicHttpSecurityMode

public System.ServiceModel.BasicHttpSecurityMode SecurityMode {get; set;}

Property Value

None : The SOAP message is not secured during transfer. This is the default behavior.

Transport : Security is provided using HTTPS. The service must be configured with SSL certificates. The SOAP message is protected as a whole using HTTPS. The service is authenticated by the client using the service’s SSL certificate. The client authentication is controlled through the ClientCredentialType.

TransportCredentialOnly : This mode does not provide message integrity and confidentiality. It provides only HTTP-based client authentication. Use this mode with caution. It should be used in environments where the transfer security is being provided by other means (such as IPSec) and only client authentication is provided by the Windows Communication Foundation (WCF) infrastructure.

TransportWithMessageCredential : Integrity, confidentiality and server authentication are provided by HTTPS. The service must be configured with a certificate. Client authentication is provided by means of SOAP message security. This mode is applicable when the user is authenticating with a UserName or Certificate credential and there is an existing HTTPS deployment for securing message transfer.
