Training for establishing risk assessment methods for network equipment, security devices, and control systems based on the revised Critical Information and Communication Infrastructure standards for the second half of 2025, and eliminating vulnerabilities through the integration of years of know-how and fast, accurate inspections and remedial actions. In particular, we expect efforts to secure inspection speed and improvement plans in accordance with the designation of ISMS-P and ISO27001 certification scopes. Gain experience with network equipment, security devices, and control systems—which are relatively less accessible and more difficult to set up environments for compared to Servers, DBs, WEB, WAS, PCs, and Cloud (Public, Private).

Security equipment cannot be inspected using scripts or solutions like databases. Experienced personnel must be assigned. Difficulty in recruiting, including experienced individuals, diligent diagnosticians, or freelancers. Numerous defects found during ISMS-P certification of security equipment; skill levels vary significantly depending on the inspector. Sharing inspection methods and management strategies (methodologies, etc.) for security equipment with those who need them.

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.

If you are planning or operating a WEB3 service but don't know "where accidents happen," you need this lecture. This course does not teach you about coins or development. Instead, it deconstructs the structure of recurring accidents in WEB3 and teaches you how to assess risks based on the boundaries of approval, signature, and authority. After taking this course, you will: ㆍBe able to read the structure of any DApp that comes your way ㆍBe able to assess risks using a checklist ㆍView WEB3 not just as a "technology," but as an "object of design."

"Understanding Manufacturing Security in the AI Era through Field Cases" is a course designed to provide an easy understanding of OT security, which is growing in importance within smart factories and AI-based manufacturing environments, focusing on real-world field cases. This lecture explains core concepts frequently encountered in manufacturing sites, such as OT, ICS, PLC, SCADA, HMI, and MES, and compares the differences between IT security and OT security. Furthermore, it examines security threats that can occur on the manufacturing floor—such as ransomware, remote access exploitation, partner account hijacking, production line shutdowns, equipment malfunctions, and data forgery—through case studies. Through this course, students will understand the basic structure of OT security in manufacturing and identify the security perspectives necessary to protect production facilities and industrial control systems. Additionally, it provides a common foundation for further learning in industry-specific manufacturing security courses.

As the adoption of generative AI accelerates, new security threats such as corporate confidential information leaks and prompt injections are surging. This course covers strategies for embedding security throughout the entire AI lifecycle, based on the National Intelligence Service (NIS) guidelines' 30 core security measures and 15 practical threat cases. It also addresses security issues in the latest AI trends, such as Agentic AI and Physical AI, and presents methods for establishing governance frameworks that can be immediately applied in practice.
