iot-security

Purpose

This skill secures IoT devices by implementing firmware hardening, encrypted data transport, strong authentication mechanisms, and safe over-the-air (OTA) updates to prevent vulnerabilities and unauthorized access.

When to Use

Use this skill when deploying or managing IoT devices that handle sensitive data, such as smart home systems, industrial sensors, or connected vehicles. Apply it during device provisioning, network setup, or when updating firmware to mitigate risks like man-in-the-middle attacks or firmware tampering.

Key Capabilities

• Firmware hardening: Applies security patches and obfuscates code using tools like OpenSSL; e.g., enforces code signing with SHA-256 hashes.
• Encrypted transport: Implements TLS 1.3 for data in transit; supports AES-256 encryption with perfect forward secrecy.
• Strong authentication: Enforces multi-factor auth (MFA) via JWT tokens; requires API keys stored in env vars like $IOT_API_KEY.
• Safe OTA updates: Verifies update integrity with digital signatures and performs rollback on failure; uses delta updates to minimize bandwidth.

Usage Patterns

To secure an IoT device, first authenticate using an API key, then apply hardening to firmware, enable encrypted channels, and schedule OTA updates. Pattern: Initialize with auth, configure security settings via CLI or API, test in a sandbox, and monitor for anomalies. For example, chain commands: authenticate, harden, encrypt, then update.

Common Commands/API

Use the OpenClaw CLI for quick tasks or REST APIs for programmatic access. All commands require $IOT_API_KEY for authentication.
