Web Application Security in JAVA
Instructor-led. In Sofia, September 2024
The curriculum goes through the common Web application security issues following the OWASP Top Ten but goes far beyond it both in coverage and the details. All this is put in the context of Java, and extended by core programming issues, discussing security pitfalls of the Java language and the runtime environment.
So that you are prepared for the forces of the dark side.
So that nothing unexpected happens.Nothing.
Open for registration.
In Sofia. Onsite.

Web Application Security in JAVA
“I didn't expect this coming! I have been coding for 15 years
and didn't believe I would still come across such important security cornerstones”.
Participant, December 2019, Stockholm.
“The whole course was one of the best I've participated in.
The content was relevant, presented and paced well. The labs complemented the material in a good way.”
