Bringing code to real life: the security challenges of IoT

You're tired, ready to take the bus home, but maybe you could take an app car instead… If only you could get some internet for your phone. You open the WiFi options. At first, there's nothing obviously free, but then, there it is! a nice printer, open and pliant. It could be a trick, of course, but you don't care that much: these things are long known as ready to share their owner's internet connection. And much more, for those with the means to get.

So we're all trying to protect our stuff, the things we own and the things we make, from this kind of scrutiny. We choose better passwords, and we learn about new leaks and threats. We need to, as people and as professionals. We even update the firmware as our devices ask for it, don't we? (I surely don't.)

The system of the Internet of Things uses four layers: the sensing layer uses sensors to get information from the environment. The network layer receives this information and sends it to the middleware layer, which stores data and works as a bridge to the last layer, the application layer: the human-machine interface that makes the product valuable.

It's beautifully conceptualized, of course, but each layer also has several vulnerabilities and concerns with security and privacy, including but not limited to active and passive attacks on your data, your device, your network, and any other devices connected to your network. It's a lot.

IoT security needs specialized testing

That's why good development teams are only as good as their code is safe. That also means that each layer needs dedicated testing. Good QA teams will use their knowledge and resources to cover every imaginable weakness (the unimaginable ones we shall leave for the future to say!). They will have access to the product to make on-site testing and access to the latest innovations in no-code testing to make it through these big challenges.

In many companies, people work under pressure to concentrate on the flashier qualities of a product, let's say, for it to be more powerful, cheaper, smaller, or prettier. But the best professionals do not let this insistence risk the product's fundamental security features!
