Learn how to safeguard your IoT devices with practical examples and **[IoT Lab](https://daily.dev/sources/iotlab)** · [@sudoyasir](https://daily.dev/sudoyasir) · 0 upvotes · 0 comments ## Summary ESP32 microcontrollers offer robust WiFi security features, but they must be properly configured. Key security measures include using WPA2/WPA3 networks, enabling Secure Boot and flash encryption to protect firmware and credentials, implementing TLS for all data transmission, securing OTA updates with signature verification, and using proper WiFi provisioning methods. Common vulnerabilities stem from hardcoded credentials, disabled certificate verification, unencrypted communication, and unsigned firmware updates. The ESP32 provides hardware-level security capabilities that, when properly enabled, make it suitable for commercial IoT deployments. ## Full article daily.dev links to this article rather than hosting it.
