IoT Security Relies on the Cloud to “Prevent Scalable Attacks”

Richard Barry joins David to talk about the role of the RTOS in IoT, the increasing complexities that need to be considered when connecting devices to the internet and how security must be a mindset from the beginning of product development. The discussion also covers the coordination of device-side and cloud-side security to look at patterns from a fleet of devices and prevent scalable attacks.

Epsiode Featuring

Richard Barry

Senior Principal Engineer & Founder of the FreeRTOS Project, Amazon

David Maidment

Director, Secure Device Ecosystem, Arm

The cloud-side plays a pivotal role. A single device can only look at itself whereas the cloud-side can look across a whole fleet of devices and notice patterns.
