Security Evaluation
1. Device Security
| Criterion | Value | Proof | Comment |
|---|---|---|---|
| Known hardware tampering | Rare | π Proof | Sealed IP65 enclosure, tampering requires opening the housing |
| Known vulnerabilities | Rare | π Proof | Minor low-risk NFC vulnerability in older firmware v1.1 and earlier, patched in newer releases |
| Prior attacks | None | π Proof | No public documented remote exploitation incidents; vulnerability requires physical NFC access |
| Updatability | Very common | π Proof | OTA firmware update via LoRaWAN or local USB |
| Category Score | Score: 2 / 3 | ||
2. System Security
| Criterion | Value | Proof | Comment |
|---|---|---|---|
| Authentication with other systems | Partial | π Proof | LoRaWAN OTAA join authentication; partial cloud API authentication |
| Communications | Encrypted with up-to-date encryption | π Proof | LoRaWAN AES-128 encryption, encrypted BLE/NFC pairing |
| Storage | Encrypted with up-to-date encryption | π Proof | Encrypted local logged measurement data, tamper-proof PDF export |
| Category Score | Score: 2 / 3 | ||
3. User Authentication
| Criterion | Value | Proof | Comment |
|---|---|---|---|
| Account management | Basic | π Proof | Single administrator account, no role-based multi-user system |
| Authentication | Basic | π Proof | Password authentication for local configuration via ToolBox App |
| Brute-force protection | Basic | π Proof | Simple retry limit mechanism |
| Event logging | Partial logging | π Proof | Measurement logs stored; limited configuration access audit logs |
| Passwords | Require change after setup with complexity requirements | π Proof | Default password must be changed on first configuration; complexity rules enforced |
| Category Score | Score: 2 / 3 | ||
