LG Uplus has become the first Korean telecom company to obtain Level 3 (ML3) certification for its cybersecurity management system (CSMS) based on the international standard ISO/SAE 21434 for automotive cybersecurity.

The certification, awarded by the global testing and certification organization TUV Rheinland, evaluates whether the cybersecurity management system for vehicle software development and operation complies with international standards.

On November 9, LG Uplus held a certification ceremony at its headquarters in Yongsan, Seoul, attended by Park Seong-yul, head of the Enterprise Business Innovation Group at LG Uplus, Hong Kwan-hee, head of the Information Security Center, and Frank Schutner, representative of TUV Rheinland. The certification is valid for three years.

As the automotive industry shifts towards software-defined vehicles (SDVs) and connected cars, the cybersecurity capabilities of vehicle software have become increasingly important. Global automakers are strengthening security standards throughout the entire vehicle development and operation process. Consequently, software suppliers are required to have systematic security management capabilities that meet international standards.

ISO/SAE 21434 is an international standard for systematically managing cybersecurity risks that may arise throughout the vehicle lifecycle.

LG Uplus secured ML2 certification last year. Following this, the company enhanced its security system during the development of in-vehicle infotainment (IVI) software and applied it to global automakers' IVI service development projects, leading to the achievement of ML3 certification.

ML3 evaluates whether the security management system is consistently applied to actual vehicle software projects, going beyond just establishing the system.

LG Uplus is pursuing the development and operation of IVI software for global automotive brands. By combining its telecommunications and media service capabilities with global-level cybersecurity management systems, the company has enhanced its competitiveness in the vehicle software business.

The certified management system will be sequentially applied to new vehicle software projects, and the company plans to continuously develop in-house cybersecurity professionals. Additionally, LG Uplus aims to enhance its vehicle security monitoring and response systems using AI and is considering implementing a vehicle software quality management system to expand its software business in the global automotive market.

Park stated, "Through this certification, we have established a cybersecurity management system that complies with international standards from vehicle software development to operation, and we have been recognized for our capability to execute this in actual projects. We will continue to strengthen our competitiveness in the vehicle software business while expanding our collaboration with global automakers as a trusted partner for differentiated vehicle service experiences, safety, and security."
