Security Evaluation

1. Device Security

Criterion Value Proof Comment
Known hardware tampering Rare πŸ”— Proof Anti-tamper steel construction; physical attack triggers loud alarm. Gen 1 BLE pairing vulnerabilities fully patched in Gen 2 firmware.
Known vulnerabilities Rare πŸ”— Proof BLE pairing vulnerability from Gen 1 was addressed; no critical vulnerabilities remain in Gen 2.
Prior attacks None πŸ”— Proof No publicly reported real-world exploitation of Gen 2 model.
Updatability Rare πŸ”— Proof OTA firmware updates available via BLE; updates released only for critical fixes.
Category Score Score: 2 / 3

2. System Security

Criterion Value Proof Comment
Authentication with other systems No πŸ”— Proof Standalone device; no smart home platform integration.
Communications Encrypted with up-to-date encryption πŸ”— Proof BLE communication uses AES-128 encryption; cellular data uses standard mobile network encryption.
Storage Encrypted with up-to-date encryption πŸ”— Proof Access credentials and GPS location data stored in encrypted on-board flash.
Category Score Score: 2 / 3

3. User Authentication

Criterion Value Proof Comment
Account management Basic πŸ”— Proof Single owner account; temporary access keys can be issued and revoked remotely.
Authentication Basic πŸ”— Proof Password-based app login; no two-factor authentication available.
Brute-force protection Basic πŸ”— Proof BLE pairing has anti-brute-force mechanism; app login has basic rate limiting.
Event logging Partial logging πŸ”— Proof Lock/unlock events and tamper alerts are logged; full account audit not available.
Passwords Require change after setup πŸ”— Proof No default access codes; user creates account password during setup.
Category Score Score: 2 / 3
