A Secure Broker is a broker that requires authentication for VMware Smart Assurance applications to use it. By default, the Broker is not secure. Universal access is provided to all VMware Smart Assurance applications. By changing the password associated with the Broker, you configure a Secure Broker. VMware Smart Assurance applications need to use the username and password to register with the Broker and also to connect to the Broker to determine the location of server applications.
