| Known hardware tampering | Rare | [] | The physical attack surface is small and rare in ordinary user scenarios. However, attacks via ports such as USB are theoretically feasible. |
| Known vulnerabilities | Rare | [Linking to CVE database, such as CVE-2023-XXXXX] | Samsung has a regular security update plan to fix vulnerabilities in the Tizen system and applications. But smart TVs as a whole are still potential targets |
| Prior attacks | Rare | [Link to security news, e.g., smart TV botnets] | There have been studies demonstrating remote attacks targeting smart TVs, but large-scale attacks specifically against this model have not been reported |
| Updatability | Very common | [Samsung Official Support Page] | Key Point: Samsung provides regular security and functional firmware updates for several years for its high-end TVs, which are usually automatically downloaded via the Internet. |

| Event logging | Partial logging | [System Logs.] | They record application crashes and system errors, but the logs of user security events may be incomplete. |
| Passwords | Require change after setup with complexity requirements | [First Login Prompt.] | After the initial setup, users will be guided to log in to their Samsung Account, but the password complexity requirements may not be strict. |
