LAB 287 – Defending Java Applications Against Null Pointer Dereference
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.
After completing this lab, the learner will understand how to defend Java 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.
