Device security

Criterion	Assessment	Evidence	Comment
Known hardware tampering	Unscored	Source	Physical factory reset is documented. This does not establish how frequently malicious hardware tampering occurs.
Known vulnerabilities	Very common	Source	The model's firmware history lists multiple CVE patches. This concerns historical vulnerabilities, not a claim that current patched firmware remains affected.
Prior attacks	Unscored	Source	Model-specific real-world exploitation frequency has not been established. Patch availability alone does not demonstrate attacks.
Updatability	Very common	Source	TRB1_R_00.07.24.6 (2026-10-12) is listed, alongside earlier releases and security fixes. Availability does not prove deployed units have installed updates.

System security

Criterion	Assessment	Evidence	Comment
Authentication with other systems	Partial	Source	Certificate-based services are configurable. Universal mutual authentication across all interfaces is not established.
Communications	HTTPS management documented	Source	HTTPS and HTTP-to-HTTPS redirection default on; remote HTTPS defaults off. This assessment is limited to management access; cipher negotiation and other traffic were not tested.
Storage encryption	Unscored	Source	Backup encryption is documented, but it does not establish encryption of resident flash. Whole-flash encryption remains unverified.

User authentication

Criterion	Assessment	Evidence	Comment
Account management	Full	Source	Separate WebUI users and configurable read/write groups are documented. SSH account management has separate constraints.
Authentication	Basic baseline; optional 2FA	Source	Password login is the baseline. The manual documents optional two-factor authentication, which requires configuration; deployed settings were not tested.
Brute-force protection	Exist	Source	IP blocking defaults on for failed SSH/WebUI logins, with a configurable threshold of 10 attempts.
Event logging	Partial logging	Source	Failed-login source, protocol and status are documented. Session visibility does not establish complete persistent auditing or retention.
Passwords	Require change after setup with complexity requirements	Source	First WebUI login requires replacing the default password; the manual specifies 8–32 characters, uppercase, lowercase, a digit and a special character.

Scope and evidence gaps

Documentation review dated 2026-10-25; no hands-on testing. Ratings describe documented features, not every firmware version or installed configuration. Hardware-tampering frequency, resident-flash encryption and real-world attack frequency remain unscored. The exact commercial release date is unverified. No overall security grade is assigned; administrator review and further evidence are needed.
