2. Basics of Web Application Vulnerability Testing

Penetration testing is a complex process that requires extensive knowledge and a systematic approach. In this course, I will try to provide you with as much information as possible in the simplest and most understandable way. As for the systematic approach, its foundation has long been accepted and is widely used by professionals and even entire organizations in slightly modified forms. In this section, we will cover the following topics:

Testing Methodology - here, we'll explain the stages involved in the testing process and briefly touch on the OWASP framework, which is the current standard for testing websites.

Attack Categories and Classifications - attacks can be directed against both the server and the user. There are numerous attacks and techniques, which have been categorized into client-side and server-side attacks with the help of OWASP.

Information Gathering and Website Scanning - this stage takes up a significant portion of the testing process. It's crucial to gather as much information as possible about the website and its users. We will discuss what to focus on, what data can be useful, and how it can be utilized later.

Required Tools - no theory is complete without practice. We will go over the programs and operating systems you'll need for penetration testing, and we'll also set up educational vulnerable systems for you to practice your skills on.
