A company can have thousands of security alerts every day—but a SOC must decide which one is normal and which one means: “WE’RE UNDER ATTACK.”

Welcome to Video 4 of the AI-Driven Cyber Security Complete Course 2026 by The Techzeen. In this lesson, you'll understand how a real Security Operations Center (SOC) works—from raw security logs and SIEM detection to alert triage, investigation, escalation, and incident response.

In This Video You'll Learn:
What is a SOC (Security Operations Center)?
SOC Roles: Tier 1, Tier 2, Tier 3 & SOC Manager
Security Logs: Login, Network, Firewall & Authentication Events
What is SIEM (Security Information and Event Management)?
Detection Rules, Correlation & Indicators of Compromise (IoCs)
Security Alerts & How Analysts Investigate Them
True Positive vs False Positive
Threat Triage, Severity & Priority
SOC Escalation: Tier 1 → Tier 2 → Tier 3
Incident Response: Identify → Contain → Eradicate → Recover → Learn
Complete SOC Workflow:
Log → SIEM → Detection → Alert → Triage → Investigation → Escalation → Response → Recovery

Where Does AI Come In?
You'll also discover how AI, LLMs and AI Agents can help modern SOC teams analyze logs, investigate alerts, prioritize threats, reduce alert fatigue, summarize evidence, and automate parts of incident response.

By the end of this video, you'll understand the complete SOC workflow and have the foundation needed to build AI-powered SOC automation and AI SOC Copilots later in this course.
