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.

[Introduction to Security Incident Response: Learning through Scenarios of Web Server Hacking, Ransomware, and Account Takeover] This course examines why various information security incidents—such as web server hacking, ransomware, account takeover, and internal penetration—occur and how they spread, categorized by incident type. Students will follow each incident scenario to understand the attack flow, analyze the core causes of the incident, and learn how to resolve issues and prevent recurrence through security architectures such as firewalls, DMZ, access control, privilege management, backup, and log monitoring. Rather than a simple explanation of security concepts, this is a scenario-based introduction to information security that provides a comprehensive understanding from root cause analysis to resolution strategies.
