OWASP IoT Top10 Assessment
- I1 Weak, Guessable, or Hardcoded Passwords
Vulnerability: Hardcoded secret key inside firmware. Risk Level: High Remediation: Remove hardcoded credentials, use unique key per device.
- I2 Insecure Network Services
Vulnerability: MQTT broker has no strong authentication. Risk Level: Medium Remediation: Enable username/password or certificate authentication for MQTT.
- I3 Insecure Ecosystem Interfaces
Vulnerability: Mobile APP interface lacks permission check. Risk Level: Medium Remediation: Verify user identity before sending control command.
- I4 Lack of Secure Update Mechanism
Vulnerability: Firmware update package is not signed. Risk Level: High Remediation: Use digital signature to verify firmware integrity.
- I5 Use of Vulnerable and Outdated Components
Vulnerability: Outdated web server component. Risk Level: Low Remediation: Upgrade web server to stable version.
- I6 Insufficient Privacy Protection
Vulnerability: Power usage data uploaded without user consent. Risk Level: Low Remediation: Clearly inform users about data collection scope.
- I7 Insecure Data Transfer and Storage
Vulnerability: Control commands transmitted in plaintext. Risk Level: High Remediation: Encrypt all remote control messages.
- I8 Lack of Device Management & Audit
Vulnerability: Cannot remotely revoke device permission. Risk Level: Low Remediation: Add remote device deactivation function.
- I9 Insecure Default Configurations
Vulnerability: Device uses same default password batch‑wise. Risk Level: High Remediation: Generate unique initial password for each device.
- I10 Poor Physical Security
Vulnerability: Physical reset can restore insecure settings. Risk Level: Medium Remediation: Limit the impact of factory reset.
