[Reflecting the latest related regulations and guidelines presented by the Korea Financial Security Institute, Financial Supervisory Service, and Personal Information Protection Commission] This is a course where you learn how an organization's security governance and internal control systems should operate through actual financial security incident cases. You will analyze the causes of incidents and response processes, and based on this, learn effective security policy establishment, risk management, and compliance response methods. The goal is to build security culture and control systems across the entire organization, going beyond technical responses.

This course covers the core aspects of TCP/IP network programming essential for online game development with a practical focus. You'll learn step by step from the basic principles of sockets to client-server architecture design, and implementation of game frameworks using custom-built network libraries. Topics covered: Basic network concepts and TCP/IP operation principles TCP programming using Socket API Packet protocol design and transmission structure implementation Client/server-based game framework development Optimization and practical tips needed for actual online game development Important notes: The course is conducted on Windows using Visual Studio. While it uses standard BSD socket API, there are slight differences from Unix-based operating systems. IOCP and Overlapped I/O are not covered.

This is Part 1 of a roadmap lecture that concisely organizes the essential computer science (CS knowledge) needed to excel in development and data, in a short period. This lecture has also been used as an in-house lecture at top domestic companies for several years. Based on 20 years of experience in actual practice, from system SW to web, app development, and data science, this lecture systematically yet easily organizes the essential core knowledge needed to excel in development and data.

For those aiming to pass the "Network Specialist Examination": This course is a learning program that condenses only the key points of the IPA Network Specialist Examination. It focuses on themes directly connected to passing the exam and is designed to help you acquire knowledge efficiently. Rather than emphasizing volume, we carefully select and explain "the essential parts you must master to pass"! Let's work hard together toward passing the Network Specialist exam!

[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.
