|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Known hardware tampering | None | [2] | There’s a tamper-alarm and one-to-one pairing protection, but physical removal attacks are possible in principle |
| Known vulnerabilities | None | [3] | Xiaomi does publish advisories, but I didn’t find a specific vulnerability for Doorbell 3 in my search |
| Prior attacks | None | [4] | I found user reports of connectivity/cloud issues (e.g. syncing failures) |
| Updatability | Very common | [5] | The device is intended to receive periodic firmware updates from Xiaomi’s servers |

| System | |||
|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Authentication with other systems | Full | [6] | The doorbell can be integrated into smart home systems via MiOT / Home Assistant, but it may not support all external platforms natively |
| Communications | Encrypted with up-to-date encryption | [7] | I did not find explicit public documentation stating that all communications use TLS/AES for this model, so this is an assumption (but reasonable given modern IoT security expectations) |
| Storage | Encrypted with up-to-date encryption | [8] | Xiaomi’s specification lists “cloud storage”, but does not clearly state whether that storage is encrypted. One must check Xiaomi’s security / privacy documentation to confirm |
| Category score | 1 | ||
| User Authentication | |||
|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Account management | Full | [9] | Users manage the device via the Xiaomi / Mi Home app and account, with control over settings, sharing, notifications, etc. |
| Authentication | Secure | [10] | The device cannot be re-paired by another account if forcibly removed; this helps secure authentication |
| Brute-force protection | Exist | [11] | It’s reasonable to expect some protection (e.g. limits, lockouts) though I did not find explicit documentation |
| Event logging | Access event logged | [12] | The system logs device status changes and usage stats, though I couldn’t confirm full audit logs |
| Passwords | Require change after setup with complexity requirements | [13] | I did not find evidence that the device or system forces password complexity or mandatory change on setup |
