Web Application Security Tools
Web application security tools help identify vulnerabilities in websites and APIs. These tools support scanning, fuzzing, manual testing, and analysis of HTTP traffic to uncover weaknesses in authentication, input validation, and server configuration.
OWASP ZAP
OWASP ZAP is an open-source web application security scanner designed for finding vulnerabilities in web apps. It includes automated scanning, intercepting proxy capabilities, fuzzing, and passive analysis.
Why it’s useful: Ideal for learning common web vulnerabilities and understanding how automated scanners identify weaknesses.
Difficulty: Beginner
Burp Suite Community Edition
Burp Suite Community Edition provides a powerful intercepting proxy, repeater, and manual testing tools for web application security. It is widely used by penetration testers and bug bounty hunters.
Why it’s useful: Teaches how to intercept, modify, and replay HTTP requests — core skills for web pentesting.
Difficulty: Intermediate
Ffuf
Ffuf is a fast web fuzzing tool used for discovering directories, files, parameters, and virtual hosts. It is highly customizable and optimized for speed.
Why it’s useful: Shows how enumeration reveals hidden attack surfaces and how fuzzing uncovers misconfigurations.
Difficulty: Intermediate
Nikto
Nikto is a classic web server scanner that checks for outdated software, misconfigurations, and known vulnerabilities. It provides quick baseline assessments of web servers.
Why it’s useful: Great for beginners learning how web servers expose risk through outdated components and insecure defaults.
