PowerShell Functions for Security Analysis
Security teams are drowning in log data—PowerShell functions let you automate analysis and cut investigation time dramatically. This course teaches you to write reusable functions that parse, filter, and correlate security events, turning raw logs into actionable intelligence fast.
AIU.ac Verdict: Ideal for SOC analysts, security engineers, and Windows administrators who need to move beyond one-off scripts into maintainable, production-grade security tooling. The 1h 50m format is tight—you’ll need basic PowerShell familiarity to keep pace.
What This Course Covers
You’ll build parameterised functions for common security tasks: parsing event logs, extracting indicators of compromise, and automating threat-hunting workflows. Liam covers function design patterns, error handling, and pipeline integration—the fundamentals that separate ad-hoc scripts from enterprise-ready tools.
The hands-on labs let you apply each concept immediately in Pluralsight’s sandbox environment. You’ll leave with reusable templates for log analysis, user behaviour detection, and incident response automation that you can adapt to your own environment on day one.
Who Is This Course For?
Ideal for:
- SOC Analyst: Automate repetitive log analysis and reduce mean time to investigate (MTTI) with parameterised functions.
- Security Engineer: Build maintainable, testable security tools that scale across your infrastructure without reinventing the wheel.
- Windows Systems Administrator: Transition from one-off scripts to function-based security monitoring and compliance reporting.
May not suit:
- PowerShell Beginner: This assumes you’re comfortable with variables, loops, and basic cmdlets; pure syntax fundamentals aren’t covered.
- Linux/Cloud-Only Practitioner: Content is Windows-centric; limited relevance if your security stack doesn’t include Windows event logs or Active Directory.
Frequently Asked Questions
How long does PowerShell Functions for Security Analysis take?
1 hour 50 minutes of video content. Most learners complete it in one or two sittings, plus time for hands-on lab practice.
Do I need to know PowerShell before starting?
Yes—you should be comfortable with basic syntax, cmdlets, and piping. This course focuses on function design and security-specific patterns, not beginner fundamentals.
Can I use these functions in my own environment immediately?
Absolutely. The course provides practical templates and patterns you can adapt to your logs, SIEM, and incident response workflows on day one.
Is this course vendor-agnostic?
Largely yes—the PowerShell function patterns apply across any Windows environment. Examples use native Windows event logs and Active Directory, but the logic transfers to third-party SIEM platforms.
