Every security professional will tell you to never trust the client. This course will teach you what this means when validating untrusted input.

Postel’s law, insecure defaults, and even our human desire to be helpful and accommodating are all places where hackers can use unvalidated input to attack your system. In this course, User Input Validation for Java Applications, you’ll learn to validate untrusted user input. First, you’ll explore unbounded input. Next, you’ll discover the difference between allowlisting, blocklisting, and sanitation. Finally, you’ll learn how to safely deserialize data against a schema. When you’re finished with this course, you’ll have the skills and knowledge of secure coding needed to protect your system against malicious input.
