Connecting Edge IoT devices with Kubernetes By Viktor Petersson on July 18, 2019 Bridging Edge IoT devices with Kubernetes Required Skill Level: Medium to Expert In my last blog post, we covered how to configure Nginx to use Mutual TLS (mTLS). This illustrated how mTLS can both simplify the back-end, while also make it more secure. In this article, we will take this one step... Continue reading
Using WoTT to Secure Access to a Mosquitto MQTT Server By Fiona McAllister on July 15, 2019 Using WoTT to Cryptographically Secure Access Between a Mosquitto Brokered MQTT Client and Server Introduction Mosquitto is a lightweight message broker for MQTT. MQTT itself is a pub-sub messaging protocol that is particularly popular amongst IoT applications due to its optimisation for high-latency networks. Together, they are effective for IoT usage being... Continue reading
Configuring Nginx with client certificate authentication (mTLS) By Viktor Petersson on July 15, 2019 Configuring Nginx with client certificate authentication (mTLS) Required Skill Level: Medium to Expert One of the cornerstones of Zero Trust Networking is Mutual TLS (known as mTLS). In simple terms, this means that each client is required to present a certificate to talk to the server. This is different compared to how... Continue reading
