3. Firmware and Software Components

Operating System：FreeRTOS, Zephyr, or bare metal

Third-party Libraries：

Bluetooth stack library (version)

Audio codec library

OTA bootloader

SBOM (Software Bill of Materials) for all components, including versions, sources, known vulnerability tracking

 

4. Manufacturing and Debugging

Factory test interfaces retained：serial commands, test points

Test mode disabled before shipment：evidence required

Production flashing tools：control measures against firmware leak or malicious injection

 

3. Lifecycle Storage and Maintenance Information

6. Additional Cybersecurity Information from R&D Party

1.The R&D party will issue cybersecurity alerts and vulnerability warnings through official channels (e.g., website, security bulletin emails). For identified vulnerabilities, the R&D party will provide corresponding solutions, including but not limited to: firmware patch updates, configuration modification guides, temporary mitigation measures, and permanent fixes. Users may contact the Security Response Center (security@singingmachine.com) to obtain the latest alert information and targeted solutions

 

2.The R&D party follows industry-leading information security management standards (e.g., ISO/IEC 27001 framework) and adopts multi-layered security protection measures, including:

 

DevSecOps: Embedding security activities in requirements, design, coding, and testing phases;

Access Control: Role-based least privilege principle and multi-factor authentication;

Data Protection: Encryption in transit (TLS), encryption at rest, and sensitive data masking;

Vulnerability Management: Regular scanning, third-party component vulnerability monitoring, and penetration testing;

Supply Chain Security: Source review and known vulnerability tracking for third-party libraries and components.

 

3.The R&D party has obtained the following certifications and audit results for its cybersecurity systems:

ISO/IEC 27001 Information Security Management System Certification (valid);

ISO/IEC 27701 Privacy Information Management System Certification (where applicable);

Third-Party Security Audits: Annual penetration testing and code security audits have passed review;

Product Security Certification: Bluetooth SIG security compliance testing passed;

Supply Chain Security Assessment: Compliant with local cybersecurity regulations (e.g., relevant IoT security acts).

 

4.Based on the most recent internal risk assessment, the security risk posture summary of the R&D party’s business environment is as follows:

 

Overall Risk Level: Low-Medium (systematic management mechanisms established);

Main Risk Points: Vulnerabilities in third-party open-source components (SBOM monitoring established), access rights to development/testing environments (hardening implemented);

Controlled Items: Network security isolation of production environment, code repository access auditing, 100% employee security awareness training coverage;

Residual Risk Acceptability: All residual risks have been reviewed and documented, remaining within acceptable range;
