In this final chapter, we presented the basic reasons why security and interoperability must be contemplated early on in the project and not added as late patchwork because it was shown to be necessary. Not only does such late addition limit interoperability and future use of the solution, it also creates solutions that can jeopardize not only yourself your company and your customers, but in the end, even national security. This chapter also presented some basic modes of attack and some basic defense systems to counter them.

As this chapter concludes the book, the reader should now be able to create solutions with IoT that are interesting, secure, and interoperable. If you review the solutions proposed in this book, you will notice how many of them solve the challenges presented in this chapter. It is my desire to thank you for your time in reading this book and also to wish you best of luck in your future endeavors.
