MEET YOUR INSTRUCTOR

Harpreet Singh Virdi, F5 ASM course instructor

Harpreet Singh Virdi, CISSP, CCSP

Welcome to the F5 ASM Classroom. My technical focus includes web application security with F5 ASM, cloud security, identity and access management, endpoint hardening, Zero Trust, and vulnerability management.

My technical toolkit includes Azure and AWS, Microsoft Entra ID / Azure AD, Intune, Fortinet, F5 ASM, and vulnerability assessment platforms such as Qualys, Tenable, and Rapid7. I hold the CISSP and CCSP credentials.

How I will teach you

We will work from first principles: understand the request, identify the security requirement, configure the relevant control, and verify the result. You do not need to know F5 ASM before starting. Unfamiliar terms are explained as they appear.

Each lesson is a separate post. Follow the course in order, use the fictional bookshop as your running example, and complete the exercises in an authorized lab. We will practice reading events, asking why a request was blocked, and making policy changes supported by evidence.

What I want you to learn

  • Explain WAF behavior in plain English.
  • Build application-specific policies with deliberate enforcement.
  • Investigate false positives without broad, unexplained exceptions.
  • Protect APIs and understand the limits of each control.
  • Document, test, recover, and maintain your configuration.

The goal is practical understanding and growing confidence through repeated practice. The course ends with a capstone assessment; operational mastery develops through continued lab work and experience.

Lesson 01: What Is F5 ASM? Your First Web Application Firewall Class

F5 ASM CLASSROOM • LESSON 01 Level: Beginner  |  Suggested study and lab time: 30 minutes Instructor: Harpreet Singh Virdi, CISSP, CCSP Start Here / Course Guide · All lessons Welcome to class Imagine running an online bookshop. Your website must accept searches, logins, and orders from people you have never met. The same public entrance also receives malformed requests and attempts to exploit software weaknesses. How do you distinguish a normal search from a suspicious request? A web application firewall (WAF) examines web traffic using rules about the application and patterns associated with attacks. F5 BIG-IP Application Security Manager, usually called ASM , is a WAF capability on the BIG-IP platform. Our task is to understand the traffic, define appropriate checks, investigate the results, and enforce protection without unnecessarily disrupting legitimate users. What you will learn Explain the purpose of a WAF in your own words. Identify where ASM fits in a web reque...
