SOC Essentials: Investigating with Splunk
Course Description
Security Operations Center (SOC) analysts spend their days hunting for threats, investigating alerts, and making sense of massive amounts of log data. Their primary tool? A SIEM (Security Information and Event Management) system. Splunk is one of the most widely used SIEM platforms in the world. This course teaches you how to use it like a pro.
You'll learn how to navigate Splunk's interface, write effective search queries, correlate events from different sources, use data models, and create dashboards. More importantly, you'll learn the investigative mindset: how to take an alert and follow the evidence to determine if an attack is real, what happened, and what to do next. The course includes hands-on labs with real security data.
This free, self-paced course takes about 15 hours to complete. It's ideal for aspiring SOC analysts, cybersecurity students, and IT professionals who want to master one of the most important tools in security operations. Upon completion, you'll earn an official Cisco digital badge.

User Reviews
"I've been trying to learn Splunk for months through documentation, but this course made it click. The hands-on labs are fantastic—real data, real investigations. The module on threat hunting was my favorite. I landed a SOC analyst job three weeks after completing this course, and my interviewer was impressed that I already had Splunk experience. Highly recommended."
"Excellent practical course. You don't just watch videos; you actually use Splunk to investigate security incidents. The search language takes some practice, but the course walks you through it step by step. The correlation module was particularly valuable—I can now connect firewall logs with endpoint data to see the full picture of an attack. Great preparation for the Splunk Core Certified User exam."
"As someone transitioning from IT support to cybersecurity, this course was a game-changer. Splunk is everywhere in SOCs, and now I can confidently say I know how to use it. The final investigation lab simulates a real incident—you have to find the evidence, piece together what happened, and write a report. It's tough but rewarding. The Cisco badge looks great on LinkedIn."
