Bonsai Information Security - Education

Web Application
Security Training

Bonsai's Web application security course focuses in teaching the attendees the different types of Web vulnerabilities and how to identify them in a manual or automated way. During the course the theoretical concepts are though, followed by hands-on practices performed in the labs that were specially developed for this course.

Our teaching experience helped us create the best Web Application Security Training, which is source code oriented: for each subject, a vulnerable source code snippet is introduced, and programming language agnostic: during the class, attendees will learn about vulnerabilities in Java, PHP, ASP.NET, ASP, Ruby and Python.

The training course was developed so that participants with varying knowledge levels can benefit from it as much as possible. During the first hour, basic HTTP concepts and generic techniques for vulnerability discovery are reviewed, gradually increasing the difficulty level until the most complex vulnerabilities are understood. Both Web application developers and computer information security experts will benefit from this training course.

For vulnerabilities like SQL injection and Remote File Inclusion, the speaker will explain and demonstrate the different exploitation techniques, in order to show the attendees the real risks related to these vulnerabilities.

To ensure the quality of our course, we have a maximum of sixteen attendees, each with its own computer provided by Bonsai, and connected to the training lab.


Provide the attendees with the knowledge, tools, and necessary techniques to understand the different types of Web vulnerabilities in existence, so in the future they can identify them themselves.

Understand the vulnerabilities in a theoretical aspect to be able to identify them in the practical lab examples.

Apply in a controlled environment and with a hands-on methodology the tools used by the professionals in the field like w3af (developed by the speaker), burp and sqlmap; in order to learn about their main features.
