AWS IoT Device Defender is a fully managed IoT Security service that will help you to keep your fleet secure. IoT Connected devices are constantly communicating with each other and the cloud using different kinds of wireless communication protocols. While communication creates responsive IoT applications, it can also expose IoT security vulnerabilities and open channels for malicious accidental data leaks. To protect users and devices, IoT devices must be secured and protected. The foundation of IoT security exists within the control, management and set up of connections between devices. Proper protection helps keep data private, restricts access to devices and cloud resources, offers secure ways to connect to the cloud, and audits device usage. An IoT security strategy reduces vulnerabilities by using policies like device identity management, encryption, and access control.
