The 10 Challenges of Securing IoT Communications

2 min readMay 4, 2015

One of the hottest topics at last week’s IoT StreamConf was security. In other words, how are we going to secure communication for billions of connected devices? How can we ensure that attackers can’t take control of our devices, steal information, disrupt services, or take down entire networks of expensive, imperative devices?

With IoT is still in its early stages, security is not fully understood and well-defined when compared to other industries, like the financial and E-commerce sectors. From the very beginning of developing an IoT product, whether it’s small-scale like a wearable device, to massive-scale IoT deployments, like an oil field sensor network or global delivery operation, IoT security must be a forethought.

In this talk, Rohini Pandhi, Product Manager at PubNub, walks through the ten challenges of securing Internet of Things communication. Rohini discusses flexible and secure messaging design patterns for IoT communication, and how they can be implemented and scaled. There are a number of security considerations, but after watching this talk, you should have a good idea of how you can secure your IoT deployment.
