The S7 has anti-pry physical design (e.g., tamper alarms) that discourages tampering.
Known vulnerabilities	None	[CVE Database Search NVD Vulnerability Feed 🔗 Proof]	No vulnerabilities (e.g., firmware flaws, connectivity loopholes) listed in official databases (CVE, NVD) or security research publications as of May 2024.
Prior attacks	None	[Krebs on Security Search Exploit-DB 🔗 Proof]	No recorded cyberattacks (e.g., remote unlock hijacking, access log tampering) targeting the S7 in public security reports or exploit databases.
Updatability	Very common	[Vilslla Home App Release Notes S7 Firmware Update Guide 🔗 Proof]	The S7 supports over-the-air (OTA) firmware updates via the Vilslla Home App. Vilslla has released 2–3 firmware updates (as of May 2024) to optimize battery life and fix minor bugs.

2. System Security

Criterion	Value	Proof	Comment
Authentication with other systems	Partial	[Vilslla Smart Home Integration Page Alexa Skill for Vilslla 🔗 Proof]	Supports limited integration with smart home systems: Amazon Alexa and Google Assistant (for voice control of "lock/unlock" commands, if enabled). No integration with enterprise systems (e.g., LDAP, MDM).
Communications	Encrypted with up-to-date encryption	[Bluetooth 5.0 BLE Security Spec WiFi Alliance WPA3 Certification 🔗 Proof]	- WiFi: WPA3 encryption (up-to-date for wireless data transmission)
Storage	Encrypted with up-to-date encryption	[Vilslla S7 Product Security Brief Third-Party Smart Lock Security Test 🔗 Proof]	User-sensitive data (fingerprint templates, passcodes) is encrypted with AES-128 (NIST-approved) in storage. Access logs are stored locally with hash verification to prevent tampering.
Category Score	Score: 2 / 3

3. User Authentication

Criterion	Value	Proof	Comment
Account management	Basic	[Vilslla Home App User Guide S7 User Manual 🔗 Proof]	The Vilslla Home App supports basic user management: adding/deleting users, assigning access types (permanent/temporary passcodes), and revoking permissions. No advanced role-based access control (RBAC).
Authentication	Secure	[Vilslla S7 Fingerprint Recognition Spec Amazon Q&A for Vilslla S7 🔗 Proof]	Supports multiple secure authentication methods: - Fingerprint (false acceptance rate <0.001%, anti-spoofing for fake fingerprints) - 6–10 digit passcodes - APP remote unlock (via account verification) - NFC card (optional accessory)
Brute-force protection	Exist	[S7 Security Features Guide User Feedback on Brute-force Lockout 🔗 Proof]	Triggers a 5-minute lockout after 5 consecutive failed password/fingerprint attempts. Repeats lockout (increasing duration to 10 minutes) for subsequent failures. Alerts sent to the APP.
Event logging	Access event logged	[Vilslla Home App Screenshots S7 Access Log Demo 🔗 Proof]	Logs all access events (time, user, authentication method) and security events (tamper alerts, low battery) locally. Logs are synced to the APP (stored for 30 days). No cloud backup of logs beyond APP sync.
Passwords	Require change after setup with complexity requirements	[S7 Initial Setup Guide Vilslla Support FAQ 🔗 Proof]	The S7 requires changing the default admin passcode (123456) during initial setup. Enforces password complexity: 6–10 digits, no consecutive/repeated numbers (e.g., 111111, 123456 are rejected).
