From Root Cause Analysis to Resolution by Information Security Incident Type

[An Introduction to Security Incident Response Through Scenarios of Web Server Hacking, Ransomware, and Account Takeovers] This course examines why various information security incidents—including web server hacking, ransomware, account takeovers, and internal intrusions—occur and how they spread, organized by incident type. By following each incident scenario, learners will understand the attack flow, analyze the key causes of the incident, and learn how to resolve the issue and prevent recurrence through security structures such as firewalls, DMZs, access control, privilege management, backups, and log monitoring. Rather than simply explaining basic security concepts, this scenario-based introductory information security course provides a comprehensive understanding of everything from analyzing the causes of security incidents to determining how to resolve them.
