Hi!

I'm wondering if someone can tell if setting Credential to the call of a web services, is secure?

I Mean, I now can instanciat a Web Service Class, but this WS need a anthentification, so I use
VB Code:
  1. Dim credentials = New System.Net.NetworkCredential(Me.txtUser.Text, Me.txtPassword.Text, Me.txtDomain.Text)

  2.  
  3. MyWebServices.Credentials = credentials
But I'm wondering if this method Is secure, in the help file I can read this
When the Credentials property is set to CredentialCache.DefaultCredentials then the client negotiates with the server to do Kerberos and/or NTLM authentication depending on how the server is configured.
But What is Kerberos and NTLM authentication ???
