국정자원 화재 교훈 잊었나...민관 '오프라인 백업' 포기

ET News | Local Language | News | Jan. 23, 2026 | Critical Infrastructure Failure

The National Information Resources Service (NIRS) has discontinued the use of offline backups—physical isolation of data—in the Daegu Center's private-partnership cloud (PPP) zone. This decision removes the last line of defense against ransomware and large-scale network outages, despite a recent fire at NIRS's Daejeon headquarters that caused significant operational paralysis. Instead of physical, offline data dispersion using fireproof safes at the Gongju backup center, the three tenant cloud service providers (Samsung SDS, KT Cloud, and NHN Cloud) shifted to an online backup method via the "G-Cloud dispersion network" connecting the Daegu and Gongju centers.

Previously, NIRS stored data on physical media like tapes, kept disconnected from any network to protect against simultaneous compromise of original and backup data by disasters or cyberattacks. The new online backup approach, with continuous network connectivity, raises concerns about vulnerability to combined physical and cyber threats. This practice conflicts with the Electronic Government Act and National Information Security Basic Guidelines, which require remote data dispersion including physical isolation for systems rated "high" in importance. While remote dispersion is technically maintained via online transmission, abandoning the air gap undermines the intended security standards.

Additionally, the globally accepted "3-2-1 rule" for data protection—three copies on two media types with one offline backup—has been disregarded. Cost and administrative convenience are cited as primary reasons for abandoning offline dispersion; cloud service providers resisted the manual handling of physical tapes required by regulations, and government authorities deferred to CSPs' autonomy within the PPP zone contracts. NIRS officials noted they lack authority to impose offline backup mandates in privately operated PPP zones.

Security experts criticize this approach, noting major global cloud providers like Amazon AWS maintain isolated backup services despite additional costs. They emphasize that sacrificing critical security measures for convenience is unacceptable for nationally important data and call for urgent development of alternative protections such as logical air gaps.

Yonhap | English | News | Jan. 23, 2026 | Shifting Geopolitical Alliances

Victor Cha, a U.S. expert and president of the Geopolitics and Foreign Policy Department at CSIS, proposed the creation of a "collective economic deterrence" pact involving South Korea, the United States, Japan, and other countries to counter China's economic pressure. This proposal comes amid concerns of possible Chinese retaliation toward South Korea following its nuclear-powered submarine project, which the U.S. has approved. The pact aims to collectively respond to any economic coercion by China, similar to the collective security principle of NATO’s Article 5, thereby deterring Chinese economic aggression rather than initiating a trade war.

Cha described China as an unreliable partner for South Korea, accusing Beijing of failing to curb North Korea's nuclear activities and ignoring UN sanctions. He emphasized that no single country in the region can effectively counter China alone, but collectively the countries possess enough leverage. The pact would treat coercion against one member as coercion against all, triggering automatic retaliation, which could impose real costs on Beijing and make it reconsider its pressure tactics.

South Korean President Lee Jae Myung has sought balanced relations with both China and the U.S., exemplified by his recent summit with Chinese President Xi Jinping. However, Cha believes this amicable approach is unlikely to withstand the fallout from the submarine deal, as China has historically retaliated against South Korea economically in response to geopolitical disputes. He called for stronger trilateral cooperation between South Korea, the U.S., and Japan, highlighting their substantial trade with China and leverage over key Chinese imports worth over $23 billion.

Cha urged the Trump administration, which holds the G7 presidency in 2027, to lead efforts in forming this economic deterrence pact and to avoid measures like tariffs on allies. He recommended that Trump explicitly oppose China's economic pressure tactics during his upcoming visit to Beijing in April to deter further coercion against allies, particularly South Korea, following the submarine project agreement.

SKT 'A.X K1', 옴니모달로 진화…“소버린 AI 마중물 될 것”

SK Telecom's ultra-large AI model, A.Dot X (A.X) K1, is advancing into an omnimodal model as part of the second phase of its independent AI foundation model project. This upgrade will enable the model to understand and process speech in real time alongside text and images, aiming to establish leadership in sovereign AI. The A.X K1, already a model with approximately 500 billion parameters, will sequentially incorporate multimodal functions, including voice and image recognition.

Professor Kim Geon-hee of Seoul National University highlighted the transition from multimodal models, which integrate text, photos, and videos, to omnimodal models that also include speech understanding. He emphasized the technical difficulty of implementing real-time voice conversations due to their bidirectional and simultaneous nature, requiring the model to handle interruptions, brief feedback, and emotional nuances. Past approaches using separate speech-to-text and text-to-speech systems faced delays and lost key information, such as breathing and emotional signals.

To address these challenges, recent developments focus on integrated language models capable of processing voice information directly. The core strategy involves fine-tuning a powerful pretrained language model using diverse data, including voice, to achieve comprehensive omnimodal capabilities. SK Telecom aims to deploy these advancements across various services like A.Dot, T map, and B tv, and expects the technology to play a central role in enhancing AI applications in gaming and mobility through partners Krafton and 42dot.

Professor Kim stressed that the success of sovereign AI depends heavily on effective use of national core data sovereignty, which includes largely unstructured data in multiple formats. An omnimodal model allows for direct training and operation of such data without relying on external platforms, thus reinforcing both digital sovereignty and sovereignty over physical infrastructure.
