[Easy for Non-Majors] Information Security Incidents: From Cause Analysis by Type to Solutions

The additional video uploads for the new course 「From Cause Analysis to Resolution of Information Security Incident Types」 have been completed.

You can now learn through the full 20-session course.

This course is designed to help you understand various information security incidents—such as web server hacking, ransomware, account hijacking, authentication bypass, internal penetration, and data leakage—through a flow of Incident Occurrence → Identifying the Problem → Root Cause Analysis → Resolution and Application.

Information security incidents can feel difficult and complex, but in reality, they often escalate as small vulnerabilities, loopholes in privilege management, issues in network structure, and gaps in response systems become interconnected.

In this lecture, we will follow the flow of such incidents in a scenario format, examining step-by-step why they occur, how they spread, and what security structures are needed to resolve them.

This course is not a lecture that covers hands-on tools in depth, but rather a scenario-based introduction to information security focused on understanding the overall flow of information security incidents and response structures.

This course is designed to be helpful for beginners in information security, developers, infrastructure personnel, IT managers, and anyone who wants to understand the flow of corporate security incidents.

With all 20 sessions now uploaded, please take the time to learn step-by-step, from the root cause analysis of information security incidents to their solutions.

Thank you.

Hello. This is Byte Detective.

The new course "Information Security Incidents: From Root Cause Analysis to Resolution by Type" has been released.

This course follows scenarios of information security incidents that can occur in actual corporate environments—such as web server hacking, ransomware, account hijacking, and internal infiltration—to understand why incidents occur, how they spread, and what structural measures are needed to prevent them.

Many people have heard of security terms such as Firewall, DMZ, WAF, MFA, backup, and log monitoring. However, it is not easy to see how these elements connect to actual security incidents or what kind of structure should be used to resolve them after an incident occurs.

This lecture explains that very flow.

Incident Occurrence → Cause Analysis → Internal Spread → Response Structure → Prevention of Recurrence

Rather than a simple explanation of security concepts, this course is structured so that you can understand security incidents as a whole flow and view them by connecting everything from the cause to the direction of the solution.

This course is not a lecture that covers hands-on tools in depth, but rather a scenario-based introductory course for understanding the structure of security incidents and the direction of response.

We recommend this to security officers, developers, infrastructure managers, IT managers, and those learning information security for the first time.

An opening discount is also being held, so we appreciate your interest.

Thank you.
