MQTT Security Fundamentals
Delve into MQTT Security and Secure IoT Data
As IoT adoption continues to expand, securing MQTT communications is paramount. This comprehensive resource is tailored for both novice and seasoned IoT professionals, offering in-depth insights into MQTT security principles.
Why security is paramount for IoT applications
Whether you are making a bank transfer, an online purchase, or accessing personal documents over the Internet, security is a top concern in our digital world every day. The idea of the Internet of Things is to connect every object to make these processes more efficient and improve the way we live and do business. 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 topic of security is more important than ever.
