IoT Security Essentials: Securing Connected Devices

Connected smart devices are everywhere, yet they remain highly vulnerable to cyberattacks. Understanding how to analyze and defend these systems is essential for anyone looking to enter the cybersecurity field. This text-based course guides you through the core principles of Internet of Things (IoT) security, taking you from a beginner to a confident practitioner who can identify weaknesses and implement robust defenses. You will learn to evaluate device architectures, analyze communication protocols, and apply modern zero-trust security concepts. What you'll learn: - Understand IoT device architecture and foundational security terminology - Analyze firmware files to identify hidden vulnerabilities and credentials - Evaluate common communication protocols like MQTT and CoAP for security gaps - Identify and mitigate the OWASP IoT Top 10 vulnerabilities - Apply modern zero-trust principles to secure connected device networks - Implement secure boot and cryptographic controls to protect device integrity The course starts with essential hardware and software concepts before moving into firmware analysis and network protocol assessment. You will progress through written case studies and practical analysis scenarios designed to build real-world auditing skills. This course is designed for beginners, developers, and aspiring security analysts who want to understand IoT vulnerabilities without needing prior hardware hacking experience.
