Prepare for passing the exam by analyzing everything from A to Z to prepare for the recently difficult practical exam.

You will learn how to analyze and quickly visualize various types of data using the Python Streamlit library and output it as a web service. You can use it when you want to apply it to your work faster than the existing web development method.

Network packet analysis is essential when conducting incident analysis and vulnerability analysis. Among the tools available, Wireshark is the most widely used, and this course covers the complete utilization of Wireshark and provides understanding through incident analysis case studies.

IT services are rapidly transitioning to cloud environments. You will learn security practices from basic virtual infrastructure construction to security threat monitoring and vulnerability diagnosis for each area to secure the Amazon AWS cloud environment.

Learn about information security professionals. What they do, what the outlook is like, and what to prepare to become one. This will be very helpful for those who are concerned about their career path.

I want to do data analysis and machine learning with Python programs. Isn't it difficult? First, you need to learn the basic grammar and basics of Python programs. This course will help you get out of the beginner stage.

This lecture guides you through data analysis using Python and how to apply it to the IT security field.

You can learn how to fully utilize Frida, which is used in mock hacking practice.

This is a practical tutorial on how to easily edit screen recording/recording files using Camtasia Studio. Using Camtasia, you can easily work as a solo instructor or IT instructor.

The most commonly used tool for web vulnerability analysis (hacking) is the web proxy server. Among them, BurpSuite is used the most. BurpSuite is planned to be regularly updated to help with web mock hacking.

When you think of IoT (Internet of Things), the first thing that comes to mind is Raspberry Pi. We will cover everything from the basic installation process of Raspberry Pi to sensor control, building and utilizing various servers, and cloud connection.

This course has been prepared with “subtitles” for those who have chosen a career in mock hacking and are curious about how to prepare.

This lecture is a free special lecture for those who have chosen a career in IT security from Boan Project (www.boanproject.com). It will be especially helpful if you have chosen a career in mock hacking.

The most important part of the security response and security control work is to monitor and remove potential security threats to your company/customer services in advance. Let’s establish and utilize a security threat monitoring plan using the OSINT search service Criminal IP.

This training is a hands-on course covering infrastructure construction using Docker container technology, vulnerability analysis, and API web server diagnostics. It is designed to comprehensively learn from the basic concepts of Docker to its application in real-world environments, security vulnerability analysis, and response.

You can clear all the challenges of the hacking competition SquareCTF (2017).

Introduction to web hacking and mock hacking for those who are new to web hacking and job seekers in related fields

This lecture provides a general guide on how to prepare while studying when you want to choose a career in IT security penetration testing, and what questions and answers to prepare for the interview. I will share my experience working as a penetration testing consultant, at large companies, and in the financial sector, and currently running a penetration testing consulting business.

IT services are rapidly transitioning to cloud environments. You will learn security practices from basic virtual infrastructure construction to security threat monitoring and vulnerability diagnosis for each area to secure the Amazon AWS cloud environment.

"Understanding Manufacturing Security in the AI Era through Field Cases" is a course designed to provide an easy understanding of OT security, which is growing in importance within smart factories and AI-based manufacturing environments, focusing on real-world field cases. This lecture explains core concepts frequently encountered in manufacturing sites, such as OT, ICS, PLC, SCADA, HMI, and MES, and compares the differences between IT security and OT security. Furthermore, it examines security threats that can occur on the manufacturing floor—such as ransomware, remote access exploitation, partner account hijacking, production line shutdowns, equipment malfunctions, and data forgery—through case studies. Through this course, students will understand the basic structure of OT security in manufacturing and identify the security perspectives necessary to protect production facilities and industrial control systems. Additionally, it provides a common foundation for further learning in industry-specific manufacturing security courses.

[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.
