OWASP IoT Top10 Assessment
- I1 Weak, Guessable, or Hardcoded Passwords
Vulnerability: PIN code can be brute‑forced. Risk Level: High Remediation: Add attempt limit and lockout mechanism.
- I2 Insecure Network Services
Vulnerability: Bluetooth service can be scanned and probed. Risk Level: Medium Remediation: Restrict Bluetooth discovery range.
- I3 Insecure Ecosystem Interfaces
Vulnerability: Unsafe mobile remote unlock API. Risk Level: High Remediation: Add multi‑factor authentication for remote unlock.
- I4 Lack of Secure Update Mechanism
Vulnerability: No easy way to patch lock firmware. Risk Level: High Remediation: Design secure OTA update for door lock.
- I5 Use of Vulnerable and Outdated Components
Vulnerability: Old Bluetooth stack with known vulnerabilities. Risk Level: Medium Remediation: Upgrade Bluetooth protocol stack.
- I6 Insufficient Privacy Protection
Vulnerability: Unlock records uploaded to cloud. Risk Level: Medium Remediation: Allow users to delete unlock logs.
- I7 Insecure Data Transfer and Storage
Vulnerability: Credential stored in plaintext locally. Risk Level: High Remediation: Store sensitive data with encryption.
- I8 Lack of Device Management & Audit
Vulnerability: No log for failed unlock attempts. Risk Level: Medium Remediation: Save all unlock and failed attempt records.
- I9 Insecure Default Configurations
Vulnerability: Default admin PIN is simple. Risk Level: High Remediation: Force PIN modification during initialization.
- I10 Poor Physical Security
Vulnerability: Lock can be damaged or disassembled physically. Risk Level: Medium Remediation: Improve anti‑disassembly hardware design.
