🦾 Robotic Slider Security0%
🦾 The Suspiciously Fun PLC Series · Security Deep Dive

Securing the seventh axis:
lock down the robot on rails.

A robotic arm bolted to a linear slider can reach across a whole cell, and the same network that drives it can just as easily drive it badly. This deep dive starts at the attack surface of a robotic slider and works all the way through IEC 62443, the real industrial-security standard. It ends with secure controller code and a live exploit-vs-defence lab.

Plain words, real depth

🌱 every chapter pairs a Beginner panel (plain language, an analogy and a one-line mental model) with an Advanced panel that carries the standard's requirements in paraphrase, plus register names and protocol detail.

62443, properly

🎚️ four chapters go deep on IEC 62443: the framework, Security Levels SL1–4, Zones & Conduits, and the Foundational Requirements. You can click through each one on a real slider cell.

🛡️
Defensive and vendor-neutral. Real standard, protocol and product names are kept exact (IEC 62443, Modbus TCP, OPC UA, CODESYS, STRIDE). Nothing here is a how-to for attackers. It shows you how to defend a machine that can move on its own.
No security background needed. Every term is defined the first time it appears.
