Challenge
Getting Started in the Lab Environment
Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!

Challenge
Identifying and Mitigating Buffer Overflows via JNI
In this challenge, you will explore Java Native Interface (JNI) security risks by identifying buffer overflows in native C code, triggering the vulnerability, and implementing mitigations using ArrayList, StringBuilder, and ByteBuffer.
-
Challenge
Identifying and Mitigating Insecure Deserialization
In this challenge, you will exploit an insecure deserialization vulnerability in a Java application. Afterwards, you will implement a secure fix using Apache Commons IO to prevent the attack.

Challenge
Knowledge Check for Validate User Input for Java
Assess your understanding of JNI buffer overflows and insecure deserialization based on the hands-on labs. Answer the multiple-choice questions to test your grasp of core vulnerabilities and defenses.
Real skill practice before real-world application
Hands-on Labs are real environments created by industry experts to help you learn. These environments help you gain knowledge and experience, practice without compromising your system, test without risk, destroy without fear, and let you learn from your mistakes. Hands-on Labs: practice your skills before delivering in the real world.
Learn by doing
Engage hands-on with the tools and technologies you’re learning. You pick the skill, we provide the credentials and environment.
Follow your guide
All labs have detailed instructions and objectives, guiding you through the learning process and ensuring you understand every step.
Turn time into mastery
On average, you retain 75% more of your learning if you take time to practice. Hands-on labs set you up for success to make those skills stick.
