We live in an era, where everybody has some kind of digital device. Most of us have at least 2 of this devices, if not more. We interact with them in a daily basis; in our work, in our home, at the school, at entertainment centers, etc. This gadgets are taking over the world, but most importantly our lives. And if this devices are being an essential part of our lives, well… we are very likely to have some security threats on our way. In our lives, we are always expose to some kind of threat, even if we like it or not, and if we have a digital device, we are expose to a different new kind of threat, that it didn’t exist before.
