Learn About How the Course Works
Before we jump in, I’d like to talk about the structure of this course, and give you a few tips on how to get the most out of it.
The course is divided into three parts, each with several chapters.
Each chapter contains text that will help you understand the key concepts. The chapters might also include:
Videos to expand on these concepts.
Screencasts to demonstrate tools.
Exercises to apply what you’ve learned.
Finally, each section concludes with a quiz where you can test your knowledge and identify areas you need to work on.
Learn About the Case Study Used Throughout the Course
In this course, you’ll take on the role of an Active Directory IT security auditor. You have been hired by a company to test the security of its internal information system. Your client’s name is MedicEx. The company specializes in pharmaceutical products that boost cognitive ability. Your contact, Mehdi Cale, is the company’s IT manager.
The examples throughout this course will be based on this scenario.
Your Goal
Your role is to:
List as many vulnerabilities as possible, along with demonstrations of how they can be exploited so that your client can replicate your attacks.
Provide recommendations on how your client can secure and monitor their information system. You will support them through this process.
