Security Evaluation
1. Device Security
| Criterion | Value | Proof | Comment |
|---|---|---|---|
| Known hardware tampering | None | — | As a household scale, motivation and instances of physical tampering are extremely rare. |
| Known vulnerabilities | None | — | Historical vulnerabilities were found in data transmission, but no widespread exploits were reported |
| Prior attacks | None | — | It has been analyzed as a case study in security research. |
| Updatability | Rare | — | The firmware is not updatable, which is its primary security weakness |
| Category Score | Score: 2 / 3 | ||
2. System Security
| Criterion | Value | Proof | Comment |
|---|---|---|---|
| Authentication with other systems | Partial | — | Data is sent to the Withings cloud via Wi-Fi and can be synced with third-party health apps like Apple Health Kit. |
| Communications | Encrypted with up-to-date encryption | — | Initially used TLS 1.0/1.1, which are now considered outdated standards. |

| Brute-force protection | Exist | — | Standard protections should exist on the server side |
| Event logging | Partial logging | — | Measurement history is viewable in the app, but detailed access logs are not available to the user |
| Passwords | Require change after setup with complexity requirements | — | Relies on user-defined password strength; no mandatory complexity requirements are enforced by the device itself |
| Category Score | Score: 2 / 3 | ||
