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
Analyzing SCADA Network Communication
You will explore the ModBus protocol and what the communication of this looks like from the packet level. This introduction will show the reading and writing of registers and the different function codes that can be used to start and stop devices. This will show how these SCADA protocols were developed with no concept of security, and as a result of this, the entire communication sequence is in clear text; furthermore, there are no protections in place from outside attackers!

Challenge
Attacks and Defense against SCADA Network Communication
Observe network communication when an attack is made against Availability and Confidentiality at the packet level. Identify the characteristics of malicious packets and network communication. Mitigate the confidentiality attack using built-in filters to control who can poll the slave device.

Welcome to the final challenge! This is your last chance to experiment in the environment. Clicking Finish Lab will end this little world that came into existence just for you,
What's a lab?
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.
Provided environment for hands-on practice
We will provide the credentials and environment necessary for you to practice right within your browser.
