Secure Java Web Application Development

The Secure Java Web Application Development course focuses on providing web developers a training in Java/JEE security to enable them to build secure web applications, incorporating essential security elements into the applications, from the development to deployment stage and beyond.  During this course, developers will initiate attacks and provide defenses, while also learning about the right practices and processes to be able to code secure web applications, including XML processing, rich interfaces, as well as RESTful and SOAP-based web services.

At the end of the program, participants will be equipped with the ability to recognize both potential as well as real security vulnerabilities, employ the right defense measures to overcome them, and also test the adequacy of those defenses. This course will also introduce developers to the most common security vulnerabilities encountered in web applications today, and enable them to examine each vulnerability from a Java/JEE perspective. Further, developers will learn to describe the threat and attack mechanisms, recognize associated vulnerabilities, and consequently, design, implement, and test effective defenses.
