About Course

This module kicks off your journey into web app security and ethical hacking! It’s designed to give you a solid foundation in how websites work, how they can be attacked, and how security professionals test them to keep things safe. 🔐💻

We’ll start with an Overview of Web Application Security, where you’ll learn why web apps are such popular targets and what kind of threats they face in the real world.

Next, we’ll dive into Web Application Architecture — the techy side of how web apps are built. Don’t worry, we’ll keep it beginner-friendly! You’ll get to know the components behind modern web applications and how each layer can be vulnerable.

Then, we’ll guide you through The Pentesting Methodology — a step-by-step approach that ethical hackers use to test systems. From information gathering to exploitation and reporting, you’ll understand how a real pentest flows.

We’ll also show you how to Set Up a Pentesting Lab on your own system so you can safely practice your skills. No need to risk hacking a live site — we’ll keep things legal and controlled! 🛠️

Finally, you’ll get an Introduction to the OWASP Top 10, which covers the most common and dangerous web vulnerabilities you should know about — like SQL Injection and Cross-Site Scripting (XSS).

By the end of this module, you’ll understand the core concepts of web application pentesting and be ready to jump into hands-on hacking with confidence. Let’s get started! 🚀

Course Content

Overview of Web Application Security
Ever wondered how hackers break into websites? 🤔 This section dives into the wild world of web app security, where we learn how to protect (and ethically hack) websites!

  • What is Web Application Pentesting?
  • Why Web Security Matters

Web Application Architecture
Web apps run on a client-server model: your browser (client) talks to a remote server, which fetches data from databases and APIs. Hackers target every layer—frontend, backend, and the connections between them. Know the structure, stop the breaches. 🔐

The Pentesting Methodology
Web app pentesting isn’t random poking—it’s a structured attack simulation to uncover flaws before criminals do.

Setting Up a Pentesting Lab
A pentesting lab is where you legally practice hacking skills without breaking the internet (or laws).

Introduction to OWASP Top 10
The OWASP Top 10 is the cybersecurity cheat sheet you didn’t know you needed. Updated every few years, it lists the 10 most critical web app vulnerabilities hackers actually exploit—from SQL injection to broken access control.
