I would recommend that you begin with this article: http://msdn.microsoft.com/en-us/magazine/cc948343.aspx Here you will find information on using Authorization within WCF services. Here's a sample of using Roles for limited who can access pieces of your service: class Service : IService { // only 'users' role member can call this method [PrincipalPermission(SecurityAction.Demand Role = 'users')] public string[] GetRoles(string username) { // only administrators can retrieve the role information for other users if (ServiceSecurityContext.Current.PrimaryIdentity.Name != username) { if (Thread.CurrentPrincipal.IsInRole('administrators')) { ... } else { // access denied throw new SecurityException(); } } } }
