Why security is paramount for IoT applications

Whether you are making a bank transfer, buying stuff online, or accessing personal documents over the Internet, in our digital and global world, security is a prominent concern every day. The idea of the Internet of Things is to connect every object to make these processes more efficient, provide more comfort, and improve our business and personal lives. But connecting objects such as cars, homes, and machines also exposes lots of sensitive data. Some of this data is not meant for the public and should be protected by the pillars of information security: confidentiality, integrity, and availability. Data leaks risk serious damage to the reputation of the affected companies. With more and more data being collected every day and more devices present in our daily lives, the crucial topic of security is more important than ever.
