Until recently, security in embedded software was not widely discussed. Now, if you attend any IoT conference, you will find it on the agenda of numerous presentations. Vendors of new frameworks, processes, or communication protocols all mention security even if it’s only an aside, as in, “Oh, and it’s secure.” Given that your system is only as safe as your weakest connection, it’s imperative to understand and plan for security threats you may encounter when you connect your system to the Internet of Things.
