The recent Coupang personal information leak has been recorded as the largest personal information breach in domestic history, marking a case where the personal information of all South Korean citizens was leaked. However, the issue of ISMS-P's effectiveness was concluded with meaningless improvement measures such as penetration testing and certification revocation, and as of December 11, 2025, Coupang and others that were subject to the Personal Information Processing Policy Evaluation System conducted by the Personal Information Protection Commission in 2024 continue to operate incorrectly in more than 10 areas of the evaluation system's standards. The reason is clearly the human factor of Coupang's personal information team, who are the best personal information experts domestically and internationally, and ISMS-P auditors, who hold the best personal information expert qualifications domestically and internationally. All of these personal information leaks, including this incident and those at G-Market, Netmarble, SKT, KT, LG U+, etc., could have been prevented with even basic common sense knowledge of the Personal Information Protection Act. However, the reality is that accidents continue to occur due to human factors, insufficient preliminary inspections, and differences in legal interpretation, resulting in customers' personal information not being protected or appropriate protective measures not being established and operated. Through this course, you can develop the ability to transparently and objectively evaluate personal information through proper personal information inspection methods and professional training to eliminate blind spots, with the hope that personal information protection for customers will be achieved.
