![]() ![]() SignalR mitigates the risk of executing malicious commands by validating the identity of the sender. For more information about persistent connections, see Authentication and Authorization for SignalR Persistent Connections. ![]() To enforce authorization rules when using a PersistentConnection you must override the AuthorizeRequest method. You apply the Authorize attribute to hubs, but not persistent connections. For more information about hubs, see Authentication and Authorization for SignalR Hubs. Without the Authorize attribute, all public methods on the hub are available to a client that is connected to the hub. You apply the Authorize attribute to either a hub or particular methods in a hub. SignalR provides the Authorize attribute to specify which users have access to a hub or method. In your hub, you can also pass authentication information, such as user name or whether a user belongs to a role, to the client. For example, you might authenticate your users with ASP.NET forms authentication, and then in your hub, enforce which users or roles are authorized to call a method. You authenticate users as you would normally in your application, and work with the results of the authentication in your SignalR code. Instead, you integrate the SignalR features into the existing authentication structure for an application. SignalR does not provide any features for authenticating users.
