Review EDX Course Security in Office 365 (Microsoft CLD245x)

Recently I took the course Security in Office 365 using the free Audit Access, the final exam and the Certificate are missing here.
The sections of the course are:
  • Threats and data breaches targeting your data
  • Office 365 Advanced Threat Protection
  • Office 365 Threat Intelligence
  • Auditing, alerting and reporting in Office 365
  • Advanced Security Management in Office 365
After each section there is a quiz, as well as an final exam with 20 questions (missing in the free version). I’ll go through each section adding some notes.

Conclusion
Unfortunately I do not have access to an Office 365 environment for testing. So I was thankful that the course gives a broad insight of the posibilites of the security configurations of Office 365. Lots of the topics come withshort  examples (like phishing, spoofing etc.) and a short video clip.

From my side more insight on the security mechanisms and more detail on Threat Intelligence would have been great.  The course goes into logging and how to find strange behaviour, malware and threat intelligence. Which was really nice to see how much effort Microsoft put into securing their cloud products.

A lot of the questions in the module assessements questions are more about configuration the platform itself or how tabs are named, I felt a bit like in a MS exam long time ago. Large parts of the content is text and not videos, most courses are a bit different here.

The course gave a good overview and insights for understanding Security in Office 365 for me, that’s what I was looking for.
