Understanding AI Auditing through Core Concepts

The semiconductor industry is a representative manufacturing sector where production facilities, control systems, partners, and data are closely interconnected. For this reason, even a small security incident or system failure can lead to production shutdowns, quality issues, delivery delays, and technology leaks. This lecture explains the OT security threats that can occur at semiconductor manufacturing sites in a way that even beginners can easily understand. Rather than focusing on complex technical explanations, it centers on what security problems can arise in the actual field, why the semiconductor industry is a target for attacks, and how security incidents impact companies. Furthermore, it examines how security threats are evolving as manufacturing environments become more intelligent with the spread of AI and smart factories.

This course examines major security threats and incident cases that can occur in the process control environment of the chemical industry, providing an easy-to-understand approach to AI-based anomaly detection and response. Participants will learn practical OT security, focusing on risks unique to the chemical industry such as production shutdowns, manipulation of process values, and hazardous substance leaks.

The recent Coupang personal information leak has been recorded as the largest data breach in South Korea's history, marking an instance where the personal information of virtually every South Korean citizen was compromised. However, the debate regarding the effectiveness of ISMS-P concluded with meaningless improvement measures such as mock hacking and certification revocation. As of December 11, 2025, companies like Coupang—which were subjects of the Personal Information Processing Policy Evaluation System conducted by the Personal Information Protection Commission in 2024—continue to operate in violation of more than 10 criteria of that evaluation system. The reason for this lies in human error involving Coupang's personal information team (comprised of top domestic and international experts) and ISMS-P auditors (who hold the highest domestic and international qualifications). With basic common knowledge of the Personal Information Protection Act, this recent leak, as well as breaches at Gmarket, Netmarble, SKT, KT, and LG U+, could have all been prevented. In reality, accidents continue to occur because customers' personal information is not protected—or appropriate protective measures are not established and operated—due to human issues such as inadequate preliminary inspections and differences in legal interpretation. Through this lecture, you can acquire the skills to evaluate personal information transparently and objectively, with the hope that personal information protection for customers will be achieved through professional training aimed at proper inspection methods and eliminating blind spots.

Developed to submit annual performance records, including the establishment of information security regulations and the preparation of various activity evidence, by applying domestic and international certification standards for Information Security Management Systems (ISMS) and internal/external audit criteria to the revised Risk Assessment standards for the Management and Physical sectors of Critical Information and Communication Infrastructure in the second half of 2025. The plan is designed to prepare for changes in the external environment (AI, etc.), internal environment (new systems and changes in employees/external staff), and new evaluation indicators and legal amendments. It aims to establish activity plans to advance information security levels compared to the previous year. Specifically, it involves objectively and meticulously inspecting various activities to strengthen accident prevention systems—such as personal information leaks caused by hacking—and establishing plans for the headquarters to supervise all departments and ensure the secure management of contractors. This includes operating DevSecOps systems following the introduction of AI systems and implementing Privacy by Design (PbD) adequacy review frameworks. The execution is based on expanding monitoring and periodic inspection report areas, external disclosure areas, data linkage system inspections (API, MyData, etc.), establishing network separation improvement plans according to N2SF, and advancing Zero Trust implementation. *Possessing over 150 references for establishing and applying the world's first and highest-level information security and personal information protection activities and system enhancement plans.
