|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Known hardware tampering | None | [] | As a kitchen appliance, physical tampering will cause malfunctions and yield no direct benefits, so it is extremely rare. |
| Known vulnerabilities | Rare | [Link to the Home Connect Platform Security Assessment] | The security risks lie not primarily in the coffee machine itself, but in the cloud platform (Home Connect) and mobile app it connects to. |
| Prior attacks | None | [] | There are no public reports of malicious attacks targeting this coffee machine, and the motivation for such attacks is low. |
| Updatability | Rare | [] | Firmware updates for such devices are usually extremely difficult to obtain or not available at all. Their security relies on the initial design. |

| System | |||
|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Authentication with other systems | Partial | [Home Connect Platform Documentation] | Authentication is performed via the Home Connect cloud service, and its security depends on the standards of this platform. |
| Communications | Encrypted with up-to-date encryption | [(Assumed) TLS is used] | Communications with Home Connect servers should be encrypted. |
| Storage | No encryption | [] | User preferences (such as coffee quantity) stored locally on the device are highly likely unencrypted, but their sensitivity is low. |
| Category score | 2 | ||
| User Authentication | |||
|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Account management | Basic | [Tchibo/Home Connect Account.] | Relies on the Home Connect account system. |
| Authentication | Basic | [Username/Password.] | Typically, it relies solely on the app account password, with no authentication on the device itself. |
| Brute-force protection | Exist | [] | Protection exists at the cloud platform level. |
| Event logging | Partial logging | [] | It may record power-on/power-off events and error codes, but there are no detailed security logs. |
| Passwords | Default/Common/Easy to guess | [] | If the user does not change the default Wi-Fi password or uses a weak password, the device may be hijacked. |
