Insufficient capability to audit new technologies (cloud management systems) due to a lack of theory and knowledge among management system inspection personnel. Training to strengthen the expertise of personnel who proactively prevent incidents by identifying management system deficiencies to protect companies from hacking. Training for existing infrastructure and penetration testing personnel to transition into management system roles. Securing definitive capabilities and materials through the provision of back data!

In cases where there is a lack of experience with electronic financial infrastructure due to only having experience in critical information and communications infrastructure, or where there is a lack of overall understanding of infrastructure projects due to insufficient experience as an Infrastructure PL or PM despite having experience with servers, DBs, networks, and security equipment, it is necessary to secure assessment capabilities for network infrastructure check items and provide assessment back-data.

As PaaS (previously categorized as WEB/WAS) in public and private cloud environments is integrated into in-house PaaS operations, this training is designed for Infrastructure Project Leaders (PLs) overseeing approximately 10 infrastructure inspection personnel, as well as vulnerability assessment specialists. The curriculum covers certification requirements such as ISMS-P, including cloud asset identification, asset classification, importance rating, and risk assessment reflection. It also addresses the 2026 Financial Company Security Standards (for Electronic Financial Infrastructure Vulnerability Analysis and Evaluation), which include the establishment and strengthening of container inspection and private cloud management system inspection items, as well as the addition and modification of virtualization and cloud items within Critical Information and Communication Infrastructure.

Providing insights and materials for overall management of penetration testers (WEB, Mobile, HTS) targeted at Project Leaders who oversee financial company mock hacking/penetration testing. Situations have occurred where "blank" reports are repeatedly submitted when no vulnerabilities are found in each part (the same applies to the public sector). Therefore, controls are implemented to ensure that inspection results for each item are produced in the same format as educational materials. Perform inspections tailored to each theme and utilize them for security reviews and internal security deliberations to verify results.

With hacking incidents occurring continuously from 2025 to the present, the addition of penetration testing to ISMS-P certification has been finalized. As the work-life balance and importance of penetration testers rise, there is a need for an environment where they can grow. Unlike other fields of information security, penetration testers can only practice and build portfolios when a proper environment is provided. Unlike the first penetration testing environment which simply provided a practice lab, this second environment allows you to build the website yourself, complete with more diverse admin functions and even actual payment features! Penetration testing scenarios for achieving practical goals have been fully implemented! ~Hone your skills according to the 2026 Major Information and Communication Infrastructure penetration testing items and evolve into one of the top penetration testers in the country!~

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.

As customer anxiety grows due to the expansion of personal information leak incidents, companies have been operating management systems that fail to properly identify personal data or implement adequate security measures. These systems have relied on operational frameworks based on ISMS-P/ISO27701 standards (managed by lawyers, etc.) and penetration testing (RED TEAMs, e.g., Coupang) composed of winners from domestic and international hacking competitions. Even companies that have not yet experienced an incident are in a situation where a leak could occur at any time. - The reason is that personal information managers are creating unmanaged blind spots themselves, such as through inadequate methods of obtaining customer consent and insufficient identification of personal information processing statuses. -> Therefore, it is necessary to share information regarding fines and penalties (as of 2024.12.8) related to domestic companies' consent forms and privacy policies. This will improve business operations by enhancing the expertise of personal information managers and ensuring that proper security measures for personal information protection are transparently disclosed to customers.

Since most large corporations and financial institutions are conducting penetration testing in addition to standard mock hacking, there is a recent need to establish new roles and secure capabilities to perform intrusions as a "RED TEAM" in the literal sense. Therefore, beyond simple WEB and APP mock hacking, we have opened a training course where participants can discover scenarios for infiltrating servers and practice executing large-scale personal information leaks. + Provision of server and website environments for penetration testing + Sharing of hacking tools and methodologies
