Security in the Internet of Things (IoT) has become a critical requirement, with recent legislation mandating ‘reasonable security features.’ It is very clear that the cost of implementing security within the IoT is necessary, and far outweighs the cost of not doing so.

Security is built up in layers; the first layer needing to be secured is the hardware layer, the second is the network layer. In this article, the network layer referenced is the Thread network layer: a low-cost, low-energy, meshed IoT network.

However, the network is a mix of wireless and wired IP technologies, so there is also a need for application level security. This comes from the OCF application layer; a secure domain where all devices and clients can securely talk to each other, say, Wouter van der Beek, senior IoT architect, Cisco Systems and Technical Working Group chair, Open Connectivity Foundation and Bruno Johnson, CEO of Cascoda, a member of the Open Connectivity Foundation.
