We discuss MQTT relative to OPC UA. Not equivalents - each brings its own strengths and weaknesses to the OT environment

SECURITY BRIEF: In this posting we explore the operational aspects of deploying resolution of exploitable vulnerabilities by manufacturers in the field. This article is a companion to "The Four Clocks for Manufacturers" This edition addresses the asset owner and operator: the entity running the estate at the operations level, on whom NIS2’s risk-management measures and Article 23 reporting clocks bind directly (where in scope), and whose engineering obligations run through

SECURITY BRIEF: Quantum computing will introduce cryptography challenges for Edge devices now and in the future. Here we look at this challenge relative to the OT environment. Quantum computing occupies an unusual position in the OT security conversation: it is simultaneously the reason current encryption will eventually fail and one of the technologies proposed to replace it. For OT and embedded environments, both sides of that story collide with the same structural problem
