OWASP IoT Top10 Assessment
- I1 Weak, Guessable, or Hardcoded Passwords
Vulnerability: Device pairing password is predictable. Risk Level: Medium Remediation: Use random pairing password.
- I2 Insecure Network Services
Vulnerability: Discovery service exposes device information. Risk Level: Low Remediation: Limit device discovery in local network.
- I3 Insecure Ecosystem Interfaces
Vulnerability: Voice command interface lacks identity verification. Risk Level: Medium Remediation: Add voiceprint verification for sensitive commands.
- I4 Lack of Secure Update Mechanism
Vulnerability: Update validation mechanism is incomplete. Risk Level: Medium Remediation: Strictly verify firmware signature.
- I5 Use of Vulnerable and Outdated Components
Vulnerability: Old audio processing library. Risk Level: Low Remediation: Upgrade third‑party libraries.
- I6 Insufficient Privacy Protection
Vulnerability: Voice recording may be collected unexpectedly. Risk Level: High Remediation: Clearly notify users when voice is recorded.
- I7 Insecure Data Transfer and Storage
Vulnerability: Voice data transmission may lack encryption. Risk Level: Medium Remediation: Encrypt all voice data transmission.
- I8 Lack of Device Management & Audit
Vulnerability: No log for voice interaction events. Risk Level: Low Remediation: Generate audit log for sensitive operations.
- I9 Insecure Default Configurations
Vulnerability: Debug shell exists in release firmware. Risk Level: Medium Remediation: Remove debug code before release.
- I10 Poor Physical Security
Vulnerability: Internal storage chip can be accessed after disassembly. Risk Level: Medium Remediation: Hardware encryption for sensitive data.
