Back to course catalogOWASP Top 10, Java Secure Coding Follow Up
Description
This course is the next step for our participants, who completed our OWASP Top 10, Java Secure Coding Fundamentals course. This is a follow up training, meaning that in order to attend this, everyone must already have the knowledge that is covered in the Fundamentals.
This course enables our participants to gain a deeper knowledge in the field, because here we emphasize the Java-specific aspects of secure coding instead of the general vulnerabilities.
At the end of the training everyone has the possibility to take an exam, where they are able to measure their level of the gained knowledge.
Participants attending this course will
- Learn client-side vulnerabilities and secure coding practices
- Have a practical understanding of cryptography
- Learn to use various security features of the Java development environment
Outline
- Client-side security
- Practical cryptography
- Secure communication in Java
- Java security services
