[Edaily Reporter Yun Junghoon ]LG Uplus(032640)has become the first domestic telecommunications carrier to obtain certification for a top-tier management system based on international automotive cybersecurity standards, marking a step toward strengthening its competitiveness in the automotive electronics business.

LG U+ announced on the 9th that it has received Level 3 (ML3, Defined-Practiced) certification for its Cybersecurity Management System (CSMS) based on the international automotive cybersecurity standard “ISO/SAE 21434.” The certification is valid for three years.

This certification was administered by the global testing and certification body “TÜV Rheinland.” It is granted following a comprehensive evaluation of whether the company’s cybersecurity management capabilities—covering the entire lifecycle of vehicle software, from planning and development to operation and maintenance—comply with international standards.

LGU+ held a certification award ceremony on the 9th at its Yongsan headquarters in Seoul, attended by Park Seong-yul, Head of the Enterprise Business Innovation Group (Senior Vice President); Hong Gwan-hee, Head of the Information Security Center (CISO/CPO, Senior Vice President); and Frank Zuttner, CEO of TÜV Rheinland Korea, among others.

As the transition to software-defined vehicles (SDVs) and connected cars accelerates, global automakers are demanding strict security systems from their parts and software suppliers. Previously, LGU+ established a management system based on ISO/SAE 21434 last year and achieved the ML2 level.

Since then, the company has continuously enhanced the security of its in-vehicle infotainment (IVI) software development processes and applied these measures to actual IVI service development projects for global automakers, culminating in this ML3 certification. ML3 goes beyond the level that merely defines a security framework (ML2); it is a stage that requires proof that the framework is consistently applied and executed in real-world projects.

LGU+, which currently supplies and operates IVI software for major global automakers such as Toyota, Lexus, and Mercedes-Benz, is now poised to significantly boost its credibility in the B2B automotive electronics market following this certification.

Going forward, LGU+ plans to sequentially apply this certification framework to new vehicle software projects, while also accelerating the development of in-house security experts and the advancement of AI-based vehicle security monitoring and response systems.

LGU+ provides services such as U+Connect, offering solutions including real-time vehicle monitoring and automatic driving logs. It is also collaborating with HyundaiMotor in the connected car sector through a telecommunications partnership.

Park Seong-yul, Executive Vice President and Head of the Enterprise Business Innovation Group at LG Uplus, stated, “This certification validates our capability to fully implement international standards in actual projects, from development through operation.” He added, “We will continue to strengthen our competitiveness in the automotive software business by expanding cooperation with global automakers while prioritizing safety and security.”
