Summary
In summary, there is a lot to know! It may seem overwhelming if you're new to the Microsoft 365 stack, but as you start learning one area, you'll see how well it translates to other areas, so I advise you to go with the flow and stick with it. As you work through understanding MDE, you'll leave with a great understanding of navigating through the security portal, making it easier to pick up knowledge in other areas.
As Microsoft builds out the Security.Microsoft.com portal, you'll find it easier to start digging into the other areas, such as Defender for Office and Defender for Identity.
With the knowledge you have picked up in those first few sections, moving into Sentinel will be a familiar one, as you continue to build on the nomenclature. With KQL, you'll be able to apply that in any portal where advanced hunting is available, as well as any Log Analytics workspace.
We're both excited to get started on the next chapter to continue your Microsoft 365 Defender adventure! See you in Chapter 2, The Evolution of Security Operations!
