Challenge
Detecting Changes in Services
In this challenge you will create a script on a corporate server in order to monitor the services running on a system. You will create the script using PowerShell. You will then attempt to detect changes to services on the system to test your new PowerShell script.
This will demonstrate how to use the built-in PowerShell capability available on common Windows operating systems to be able to perform customized audit and security detections. This will help you and your organization protect critical servers by using only known services.

Challenge
Detecting Port Changes
In this challenge you will need to create a script on a corporate server in order to identify new ports created on the system. You will create the script using PowerShell. You will then attempt to create a new port on the system to test your new PowerShell script, simulating a malicious process.
This will demonstrate how to use the built-in PowerShell capability available on common Windows operating systems to be able to perform customized security detections. This will help you and your organization protect critical servers in a repeatable way.
Building further on your learning, you will access findings by remoting from your blue team workstation acting as a central collection and analysis point.
