Lesson 9: Data Sources
This lesson explores data sources used in cybersecurity investigations, with a focus on how log data and other security information sources are collected, analyzed, and interpreted to support incident detection and response. In modern enterprise environments, security teams rely on large volumes of data generated by systems, applications, networks, and security tools to identify suspicious activity and reconstruct events. Understanding how to use these data sources is essential for effective threat detection, forensic analysis, and decision-making.
By the end of the lesson, you should be able to:
- Identify common sources of security-relevant log data
- Explain how logs support security investigations and incident response
- Understand the role of different systems in generating security data
- Describe how data correlation improves threat detection and analysis
