How Airwall Works
Tempered Networks Airwall technology uses the Host Identity Protocol and a cloud-based policy orchestration platform to create new overlay networks built on encrypted and authenticated communication. The policy manager (a.k.a. the conductor) enforces configured digital policies that control connections within the cloaked overlay system. The default position for the policy manager is 'zero trust', i.e., only allowing connections between continuously authenticated and authorised entities. Once a communicating device authenticates itself correctly, an encrypted tunnel is created through which data flows. This cyber security technique offers advantages such as the creation of an always-on and software-defined security perimeter protecting device-to-device, device-to-cloud and device-to-user interactions. Airwall achieves this by using Host Identity Protocol to create a cloaked and micro-segmented network which overlays a building's existing network infrastructure, making the solution also highly cost-effective. And in addition, a new level of authentication for connected building systems is created, allowing for greater system automation of functions such as heating and cooling, lighting, security and airflows.
"When it comes to buildings, we must create easily implementable cyber security defences as we're often dealing with critical infrastructure, including assets such as data centers and hospitals," said
Technology integration
Tempered Networks Airwall technology is being integrated into Johnson Controls Openblue platform which is increasingly recognised as a leading smart building software platform with advanced AI-enabled building management capabilities. Openblue provides a flexible computing approach for converging building technologies and making those technologies more insightful, powerful, and optimised through edge AI and through full machine learning in the cloud. The ultimate goal is to make all buildings smarter, healthier and more sustainable.
"Digital transformation is the primary way we'll make the world's buildings more autonomous and resilient," said
The acquisition of Tempered Networks builds on the previously announced selection of the company as a core component of Johnson Controls Openblue platform and services. The integration of Tempered Networks' security technology further builds on other recent acquisitions including Foghorn whose technology is taking the company's edge AI capability to new levels for compute-constrained devices. It also complements partnerships with Pelion and
