IoT Security Basics

Summary

Internet of Things devices often ship with weak default credentials, unpatched firmware, and minimal security controls — a rapidly growing and often poorly secured attack surface.

How to Learn This

1Research a real IoT botnet (like Mirai) and how it exploited weak default credentials at scale.
2Learn why IoT devices are harder to patch and monitor than traditional computers.
3Understand network segmentation (Phase 2) as a key mitigation for IoT device risk.
