Introduction to Log Analysis
Learn how SOC analysts analyze logs in real-world environments by understanding log types, structures, searching techniques, pattern detection, and hands-on analysis using Splunk, Wazuh, and ELK Stack.
Overview
Log analysis is the foundation of every security investigation. Before alerts, before automation, and before response — SOC analysts rely on logs to understand what happened, when it happened, and how systems were affected.
In this project, you will:
- Understand what log analysis is and why it matters in SOCs
- Learn different types of logs analysts work with
- Understand log structure, fields, and context
- Practice searching, filtering, and investigating logs
- Perform hands-on log analysis using:
- Splunk
- Wazuh
- ELK (Elastic Stack)
- Understand how logs support incident detection, validation, and response
This project focuses on analyst thinking and investigation mindset, not just tools.
