![]() This high level of functionality means that Tableau comes with a high price tag relative to some other options on the BI market.Featured Business Intelligence Software.Looking for a new BI software? We’re here to help.Why choose Microsoft Power BI over Tableau.Why Tableau May Not Work For Your Company.If the JWT can be successfully verified, Tableau will render our Viz component. Our application will sign the JWT with our Connected App secret value and Tableau will attempt to verify our JWT with the same Connected App secret. The signature is the key ingredient used to build that trust. This is where we add data identifying the Connected App, our Tableau User Name, and some additional information. The payload contains the key information being transmitted. The header contains metadata about the JWT, such as the algorithm used to encode the JWT and the token type. JWTs are generally made up of three parts: In the most basic terms, JWTs follow an open, industry-standard allowing us to pass encoded data between our web applications and servers. Therefore, if you are able to present the secret, Tableau can authenticate your access. This is possible because the key is obtained from Tableau and only from Tableau. By signing the JWT with this secret, Tableau will be able to verify that you are a permitted user. And the JWT includes a signature or a special key. See, when we build our Connected App we’ll create a JWT. This agreement is essentially how the signature of a JSON Web Token (JWT) verifies that you are who you say you are in Connected Apps. Therefore, it is this secret that is used to create trust between the patron and the speakeasy bouncer. All the speakeasy bouncer needs to do is remember the valid secret and verify that those trying to get in do in fact possess the right secret. This is even more complex than the first.īy simply sharing the secret with everyone who enters the club the speakeasy doesn’t need to keep any lists. In this scenario, you need to duplicate the long list and make sure all of the lists are in sync. The second scenario is one where you have created multiple speakeasy bouncers - or authentication servers. This is going to require storage resources, time, and computing power. In order to securely authenticate, you need to both store this large list somewhere and perform the look-up for everyone trying to get through the door. In the first scenario, the list of who’s allowed to enter is ten million names long. At a speakeasy, you will need to enter a certain code on a payphone, perform the special handshake, present a red rose, or whatever other flavor of secret the speakeasy requests for the night. Once there we need to provide our secret. So, once past the bouncer, we make our way to the entrance of the speakeasy. Now, we need to make one modification to this scenario - those who successfully enter the club get a secret that when presented to the bouncer of the speakeasy authenticates their access to additional resources. Anyone who makes it past the bouncer or login screen will have a chance to enter the speakeasy or access the Tableau Viz respectively. You can think of it as the first line of defense. With Tableau’s Connected Apps this initial authentication step is carried out however you see fit for your application. Presenting your ID at the club is very similar to what takes place when visitors of our application provide their username and password to sign in. Like for any secured application, at a speakeasy, you can’t even enter the club before you prove your identity and that you’re of age to drink. ![]() However, this content is protected.įor the sake of this example, let’s place the entrance to the speakeasy in the back of a club. Like the users visiting our application, patrons of a speakeasy have content they intend to consume.
