This course is a step-by-step learning program that covers network programming from fundamentals to hands-on practice. First, we examine the origins and development of the Internet to understand how today's network environment was formed. Next, we learn the structure and operating principles of the TCP/IP protocol, which is the core of networking, to build a theoretical foundation. In the practical stage, we implement actual network communication using the Socket class, TcpListener, and TcpClient classes provided by C#, and experience client-server architecture. Through this, you can understand the actual data transmission and reception process and network connection procedures beyond simple theory. Finally, we visually implement network programs by creating user interfaces (UI) using WinForm. We practice enabling connection, message transmission, and reception through button clicks, developing the ability to create network application programs that can be utilized in real-world environments.

This lecture is about automotive ECU cyber security based on a basic understanding of cryptography.

As personal information breach incidents expand, customer anxiety grows. During this time, companies have been operating management systems that cannot properly identify personal information and implement safety measures through ISMS-P/ISO27701-based business system operations (lawyers, etc.) and penetration testing (RED TEAM composition, e.g., Coupang) consisting of domestic and international hacking competition winners. Even companies that haven't experienced incidents yet are in a situation where breaches could occur at any time. -The reason is that personal information managers themselves create unmanaged blind spots, such as insufficient methods for obtaining customer consent and inadequate identification of personal information processing status. ->Therefore, there is a need to improve work processes by sharing fines/penalties for domestic companies' consent forms and processing policies (as of December 8, 2025) to transparently disclose to customers the expertise of personal information managers and proper personal information protection safety measures.

Training on assessing the current status and inspecting personal (credit) information processing systems, pursuant to the Notification on Personal Information Security Measures and Appendix 3 of the Supervisory Regulations on Credit Information Act.

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.

Nationally Certified Industrial Security Manager: "Final update of the newly renewed version is complete"!! The 2026 exam schedule is expected to be announced between February and March on the following site (https://license.kaits.or.kr/license/web/board/brdList.do?menu_cd=000021). This course is designed to help you obtain the Nationally Certified Industrial Security Manager certification by providing a systematic understanding of industrial security from a management perspective. Rather than focusing on rote memorization, the content systematically organizes the concepts, structures, and flows of industrial security so that even non-security majors can understand it, preparing you for the exam while also supporting practical work and career expansion.

Incident response is less about mastering tools and more about knowing what to judge first. Rather than focusing on how to analyze malware, this course explains the realistic thought process of determining **"whether the current situation is an actual incident and what actions to take first."** Using webtoon-based real-world scenarios, we have organized the entire flow of incident response—from identifying signs of intrusion to incident assessment, initial response, containment, and analysis/forensics—in a way that even non-experts can understand. This is not just a collection of fragmented technical explanations; it is a course where you learn the decision-making criteria and response perspectives that practitioners can apply immediately in the field.

This course carefully selects the core systems that beginners must know in the vast field of information security. Instead of rigid theory, it's structured to help you intuitively understand system principles through clear analogies and practical examples. With this single course, you can grasp the big picture of information security systems as a whole and develop practical skills.
