OWASP IoT Top10 Assessment
- I1 Weak, Guessable, or Hardcoded Passwords
Vulnerability: Hardcoded token inside firmware. Risk Level: Medium Remediation: Avoid hardcoded authentication token.
- I2 Insecure Network Services
Vulnerability: Alarm notification service lacks access check. Risk Level: Medium Remediation: Verify message sender identity.
- I3 Insecure Ecosystem Interfaces
Vulnerability: API for alarm status query is not protected. Risk Level: Medium Remediation: Add authentication for status query API.
- I4 Lack of Secure Update Mechanism
Vulnerability: Rare security patch for detector. Risk Level: High Remediation: Provide long‑term security update support.
- I5 Use of Vulnerable and Outdated Components
Vulnerability: Low‑cost MCU with old code library. Risk Level: Low Remediation: Audit embedded code regularly.
- I6 Insufficient Privacy Protection
Vulnerability: Location information uploaded together with alarm. Risk Level: Low Remediation: User can choose whether to upload location.
- I7 Insecure Data Transfer and Storage
Vulnerability: Alarm data may be tampered. Risk Level: High Remediation: Add message integrity check.
- I8 Lack of Device Management & Audit
Vulnerability: Cannot know whether detector is offline. Risk Level: Medium Remediation: Report device heartbeat status.
- I9 Insecure Default Configurations
Vulnerability: Alarm threshold setting can be modified without authorization. Risk Level: High Remediation: Require authentication to change threshold.
- I10 Poor Physical Security
Vulnerability: Detector can be covered or removed physically. Risk Level: Medium Remediation: Add tamper detection alarm.
