What you'll learn

In the world of application development, all incoming data is a potential threat. Improper input validation is the root cause of many of today's most severe security vulnerabilities. In this course, Data Input Validation for Java Applications, you'll learn a comprehensive toolkit to build a robust defense against these attacks. First, you’ll explore the importance of input data validation and learn to implement basic validation in plain Java. Next, you’ll discover how to implement advanced validation using Bean Validation API and how to create custom validation logic. Finally, you’ll learn how to validate files, objects, and other data. When you’re finished with this course, you’ll have the skills and knowledge of data input needed to develop more secure, reliable, and resilient Java applications.
