Public Cloud Security Certification Process Unified Under NIS Review; "Need to Resolve Opacity Controversy"

Seoul, South Korea – In a significant move to streamline the digital infrastructure landscape, South Korea is set to overhaul its public cloud security certification process. By the latter half of 2027, private companies seeking to enter the public cloud market will navigate a unified security verification system managed solely by the National Intelligence Service (NIS), replacing the current cumbersome dual-certification structure.

Currently, companies must obtain security certification from the Ministry of Science and ICT (MSIT) before undergoing a secondary review by the NIS. This two-step approach has drawn criticism for its overlapping assessment criteria and excessively stringent standards, often leading to significant delays in market entry. The proposed reform, announced by both the MSIT and NIS on April 20th, seeks to eliminate these redundancies and expedite the process.

The new framework will consolidate verification standards, focusing on criteria directly relevant to public security requirements within the cloud computing context. This consolidation is expected to alleviate the burden on companies and foster a more agile environment for cloud service providers. To address potential concerns regarding the NIS's singular authority, a joint public-private review committee will be established. This committee, comprising experts recommended by the MSIT and industry stakeholders, will be tasked with ensuring the fairness and validity of the NIS-led assessments.

Furthermore, the existing CSAP (Cloud Security Assurance Program) will be integrated with the ISMS (Information Security Management System), which serves as the mandatory certification for private sector information security. This integration allows businesses aiming to enter the private cloud market to voluntarily pursue ISMS certification for cloud services. However, experts like Professor Kim Seung-joo of Korea University's Graduate School of Information Security emphasize the need for greater transparency. He points out that past NIS security reviews lacked clarity, with interpretations varying based on the reviewer and assessment criteria not being publicly documented. The call is for a transparent disclosure of evaluation standards and methodologies, akin to international practices, enabling companies to prepare for certification with predictable guidelines.
