What you'll learn

Perform Real SOC alert triage and prioritize security alerts based on severity, risk, and potential business impact.
Collect and document security evidence, investigate affected entities, analyze related alerts, and build an investigation timeline.
Follow a practical Tier 1 to Tier 2 SOC escalation workflow and perform deeper investigation and attack reconstruction.
Assess incident scope and impact, recommend response actions, and identify detection engineering improvements.

Requirements

No prior SOC experience is required. Basic cybersecurity concepts and familiarity with web browsers are helpful. A computer and internet connection are required.

Description

Learn how a SOC analyst investigates a security alert from initial detection through investigation, escalation, correlation, timeline reconstruction, and response validation.
This hands-on SOC Alert Investigation Lab takes you through a realistic end-to-end investigation usingMicrosoft Defender XDR and AWS security telemetry.
You will follow the same investigation progression used in a SOC environment, starting withTier 1 alert triage and moving into deeperTier 2 investigation.
Throughout the lab, you will learn how to
- Triage a high-severity security alert
- Identify affected users, hosts, and cloud resources
- Collect and document investigation evidence
- Decide when an alert should be escalated from Tier 1 to Tier 2
- Correlate multiple alerts and related security activity
- Reconstruct an investigation timeline
- Assess incident scope and potentially affected resources
- Investigate AWS root-account credential activity
- Analyze access-key and MFA-related security events
- Identify investigation gaps and telemetry limitations
- Analyze automated remediation results
- Understand whyautomation completion does not necessarily mean successful remediation
- Validate whether containment can actually be confirmed
- Document findings in a professional security incident investigation report
A major focus of this course isinvestigation accuracy. You will learn to distinguish between what the telemetry actually proves, what is merely correlated activity, and what still requires validation.
The course also demonstrates an important real-world SOC principle:detection does not equal containment. In the case study, an automated response workflow completes, but the underlying AWS remediation returnsAccessDenied. You will see why an analyst must independently verify remediation rather than simply trusting an automation platform's completion status.
You will receive a practicalSOC Investigation Workbook that can be used throughout the lab to structure your investigation, document evidence, reconstruct timelines, assess scope, and validate containment.
By the end of the course, you will understand how to approach a SOC investigation systematically and how to produce professional investigation documentation suitable for a security operations environment or portfolio.
This course is designed for learners who want practical exposure to SOC investigation methodology rather than purely theoretical security concepts.

Who this course is for

This course is for aspiring SOC Analysts, junior cybersecurity professionals, IT professionals, students, and career changers who want practical experience investigating security alerts. It is also useful for analysts preparing to move from Tier 1 alert triage into Tier 2 investigation and incident response.
