Security Evaluation

1. Device Security

Criterion	Value	Proof	Comment
Known hardware tampering	Rare	🔗 Proof	Rare is a contributor-supplied qualitative assessment based on physical disassembly being possible and no public in-the-wild hardware-tampering reports identified in the supplied assessment. The manufacturer documents external ports and a reset button, not a measured tampering frequency. Absence of identified reports is not proof that no tampering has occurred.
Known vulnerabilities	Very common	https://www.synology.com/en-global/security/advisory/Synology_SA_23_10 🔗 Proof	Qualitative historical rating: multiple SRM 1.3 vulnerabilities have been officially disclosed. SA-22:25 was fixed in 1.3.1-9346-3; SA-23:10 in 1.3.1-9346-6. This is not a claim that current patched firmware remains vulnerable.
Prior attacks	Rare	🔗 Proof	Rare is a provisional frequency judgment, not a measured rate. A Synology Router Team notice dated 24 August 2023 confirms SRM exploitation attempts associated with SA-22:25. It does not identify a count of compromised RT6600ax units.
Updatability	Very common	https://global.download.synology.com/download/Document/Software/UserGuide/Os/SRM/1.3/enu/Syno_UsersGuide_Router_1.3_enu.pdf 🔗 Proof	The router supports free SRM updates, manual firmware installation and configurable update checking/installation. Repeated security-fix releases are documented. Very common describes ongoing update support, not a guaranteed schedule.
Category Score	Score: 2 / 3

2. System Security

Criterion	Value	Proof	Comment
Authentication with other systems	Partial	https://global.download.synology.com/download/Document/Software/UserGuide/Os/SRM/1.3/enu/Syno_UsersGuide_Router_1.3_enu.pdf 🔗 Proof	Partial is a capability-based assessment: SRM supports directory integration and certificate-based secure connections, but universal mutual authentication across all enabled services is not established. Protocol and configuration dependent.
Communications	Encrypted with up-to-date encryption	https://global.download.synology.com/download/Document/Software/UserGuide/Os/SRM/1.3/enu/Syno_UsersGuide_Router_1.3_enu.pdf 🔗 Proof	Assessment assumes WPA3 Wi-Fi and HTTPS management are configured. WPA3 and HTTPS are supported; legacy wireless modes and HTTP are also available. This rating does not imply all traffic is encrypted by default.
Storage	No encryption	https://fehmijaafar.net/wiki-iot/index.php/Methodology 🔗 Proof	No encryption is selected using the contributor-supplied assessment of internal firmware/flash storage; Partial is not an available form option. The supplied assessment states that internal 4 GB eMMC firmware/partitions are unencrypted, but capacity and internal encryption status have not been independently verified. Official SRM documentation establishes optional encrypted shared folders on external USB storage, not encryption of internal flash.
Category Score	Score: 2 / 3

3. User Authentication

Criterion	Value	Proof	Comment
Account management	Full	🔗 Proof	Administrators can create, edit and delete users and assign per-user folder permissions. Rates documented account-management capability, not a tested deployment.
Authentication	Basic	https://global.download.synology.com/download/Document/Software/UserGuide/Os/SRM/1.3/enu/Syno_UsersGuide_Router_1.3_enu.pdf 🔗 Proof	Basic is a conservative recovery-aware assessment. Two-step verification is available and can be enforced, but a physical four-second soft reset resets administrator-level passwords. It is not classified as recovery-proof authentication.
Brute-force protection	Exist	🔗 Proof	Auto Block can block client IP addresses after a configurable number of failed logins within a specified time. Rates available protection; activation and thresholds depend on configuration.
Event logging	Partial logging	https://kb.synology.com/en-sg/SRM/help/SRM/LogCenter/logcenter_search?version=1_3 🔗 Proof	Conservative partial-logging assessment: Log Center supports local event collection, search, archival and export. Completeness of access-event coverage across all services has not been independently tested.
Passwords	Require change after setup	https://kb.synology.com/en-sg/SRM/help/SRM/ControlPanel/user?version=1_3 🔗 Proof	The setup wizard requires creation of an administrator account. The second option is used for mandatory initial credential creation; optional configurable password-strength rules are documented, but mandatory complexity at first setup is not established.

RESEARCH DRAFT - ALL RATING CONTROLS COMPLETED; SOURCE LIMITATIONS REQUIRE REVIEW. Hardware tampering (Rare) and internal-flash storage (No encryption) follow the contributor-supplied assessment. These two selections are not independently verified manufacturer findings; the supplied 4 GB eMMC capacity and unencrypted internal-partition claim still require a direct technical source. No encryption refers only to internal flash, not to optional encrypted external shared folders. Other ratings are qualitative assessments with scope limitations in each comment, not measurements of attack frequency or observations from a tested unit. Communications assumes WPA3 and HTTPS are configured. Historical SRM vulnerabilities and the 2023 router-team attack notice do not establish compromise of every RT6600ax or vulnerability of current patched firmware. Initial administrator credential creation is mapped to the closest password option; compulsory first-setup complexity is not established. Unspecified hardware details remain marked as such.
