Penetration Testing - Web Application Security

This basic training course is designed for QA or penetration testers and imparts in-depth basics for the security of web-based applications.

The participants will be able to comprehend complex security-relevant correlations in web applications, to identify the most common vulnerabilities and to derive basic approaches for establishing sustainable security.

The seminar includes the work of the OWASP (Open Web Application Security Project) considered to have a significant impact on the future. Vulnerabilities and specifics of web browsers and web applications are discussed thoroughly. Each vulnerability is considered with regard to its most effective verification technique and general countermeasures.

The training includes a variety of practical exercises for which our convenient mobile training environment is used. The participants learn to understand the vulnerabilities by solving tasks at different difficulty levels before discussing them in the group.

The participants are encouraged to use their own laptop with their own preferred working environment and don’t have to adapt to the training environment.

All contents can be adapted specifically to your needs!
