Day 54: IoT Security Basics — Why Most IoT Projects Fail (And How to Fix Them)

Welcome to Day 54 of 100 Days of Tech! 🔐 So far, we’ve built: Sensors ESP32 devices MQTT communication Cloud dashboards A complete end-to-end IoT project Now comes the most ignored but dangerous part: Security. Most IoT projects don’t fail because of hardware or code — they fail because security was treated as an afterthought. 🔹 What you’ll learn in this video (6–7 minutes) ✔ What IoT security really means ✔ Why IoT devices are easy targets ✔ Common IoT security mistakes beginners make ✔ Real-world IoT attack examples ✔ How data can be intercepted or manipulated ✔ Basic security practices every IoT builder must follow ✔ How companies think about IoT security in production 🔹 Why IoT Security Is Hard IoT devices are: Low power Always connected Deployed in the real world Often unattended That makes them perfect targets. 🔹 Common IoT Security Failures 🚫 Hardcoded passwords 🚫 Unencrypted MQTT data 🚫 Open ports & public brokers 🚫 No device authentication 🚫 No firmware update mechanism 🚫 Blind trust in cloud services 🔹 Basic IoT Security Principles (Beginner Friendly) Device authentication Encrypted communication (TLS/SSL conceptually) Secure credentials handling Network isolation Regular firmware updates Logging & monitoring No heavy crypto. Just correct thinking. 🔄 Secure IoT Data Flow (Mental Model) Sensor → ESP32 → Encrypted MQTT → Secure Cloud → Authenticated App Security is not a feature — it’s a layer. 💼 Career relevance (India | 2026+) Understanding IoT security helps you grow into: IoT Engineer (production-ready) Embedded Security Engineer Edge AI Engineer Industrial IoT roles System & Product Architect (long term) Security knowledge = senior-level thinking.
