What is a SIEM? | Zero to SOC Analyst Ep. 1

Welcome to Episode 1 of the 8-Week SOC Analyst Foundation, the free course that takes you from absolute beginner to job-ready SOC analyst. In this episode, you'll learn what a SIEM actually is, why every Security Operations Center is built around one, and the four core things a SIEM gives you that you can't get without it. This is the foundation for everything else in the course. The next seven weeks of Windows log analysis, phishing investigations, authentication attacks, and detection writing all assume you can search and pivot through a SIEM with confidence. By the end of this video, you'll be able to answer the very first question every SOC interviewer asks: what is a SIEM and why do organizations use them? 🧙 New to cyber?
