Training Course: Testing Web Application Security


This course provides the knowledge and skills Testers need to detect security vulnerabilities in web applications using a combination of manual and automated methods.  Testing Web Application security is not intuitive and to be effective you need an understanding of web application design, HTTP, Javascript, browser behavior, and potentially other technologies such as AJAX, JSON, and XML.


This course is designed for experienced QA staff who wish to gain the skills and learn the techniques necessary to accurately and thoroughly assess the security of web applications.


2 Days


  • Recognize common web application security vulnerabilities and how to determine if they are present in web applications
  • Recognize web application design assumptions and how to exploit them
  • Be familiar with the capabilities of various Browser Proxies
  • Be familiar with the capabilities of various Penetration Testing tools
  • Be prepared to detect Access Control Vulnerabilities
  • Be prepared to detect SQL Injection Vulnerabilities
  • Be prepared to detect Cross-Site Scripting (XSS) Vulnerabilities
  • Be prepared to detect Authentication and Session Vulnerabilities
  • Be prepared to test web application security


Ideally, the classroom environment should support the technologies employed within the firm in regards to the Web Server, testing tools, and database.
