Security Evaluation
1. Device Security
| Criterion | Value | Proof | Comment |
|---|---|---|---|
| Known hardware tampering | None | — | No built-in hardware tamper protection; open board design. |
| Known vulnerabilities | Rare | 🔗 Proof | Default credentials in older OS versions; patched in current Raspberry Pi OS. |
| Prior attacks | None | — | No widespread targeted attacks on default configurations. |
| Updatability | Very common | 🔗 Proof | Frequent OS and firmware updates available. |
| Category Score | Score: 2 / 3 | ||
2. System Security
| Criterion | Value | Proof | Comment |
|---|---|---|---|
| Authentication with other systems | Full | 🔗 Proof | Linux-based; highly customizable authentication integration. |
| Communications | Encrypted with up-to-date encryption | 🔗 Proof | Linux-based; supports TLS, SSH, VPN as configured. |
| Storage | Encrypted with up-to-date encryption | 🔗 Proof | Linux-based; full-disk encryption configurable. |
| Category Score | Score: 1 / 3 | ||
3. User Authentication
| Criterion | Value | Proof | Comment |
|---|---|---|---|
| Account management | Full | 🔗 Proof | Linux-based; multi-user and permission management. |
| Authentication | Secure | 🔗 Proof | Linux PAM; supports strong passwords, keys, 2FA. |
| Brute-force protection | Basic | 🔗 Proof | Linux-based; can be configured (e.g., fail2ban) but not default. |
| Event logging | Access event logged | 🔗 Proof | System logs (syslog) record access events. |
| Passwords | Default/Common/Easy to guess | 🔗 Proof | Historical default pi/raspberry; current OS forces user-defined password at setup. |
| Category Score | Score: 2 / 3 | ||
