Course Description

The Defending Against Null Pointer Dereference lab assesses the learner’s ability to fix code that contains a Null Pointer Dereference. This vulnerability occurs when the application dereferences a pointer that it expects to be valid but is NULL, typically causing a crash or exit.

Learning Objectives

After completing this lab, the learner will understand how to defend C# applications against null pointer dereference attacks that bypass security logic or cause the application to reveal debugging information that will be valuable in planning subsequent attacks.
