Security is something that all applications must take into consideration. SignalR just taps into existing infrastructure, both for the client and the server side, making this possible. All we need to do is authenticate and use the infrastructure to our advantage to get our app secured. You should not only be able to apply security in the form described in this chapter, but also get an idea on how to move forward with even more security, such as applying SSL. The next big step now is to make our application scale. With the scale-out options of SignalR, one should be capable of truly scaling to any need. The next chapter will go into depth on how to scale with different options, even into the cloud.
