Microsoft Defender Weekly Wrap - Issue #88

Things from Me

Happy Friday everyone!

Another week, another fantastic newsletter issue.

Toward the end of next week, I’ll be taking a couple weeks off. The time off will be in preparation for some hard-core focus on helping get Microsoft Ignite off the ground this year. For the first part of my time off, I’m headed to Ohio Amish country for a long overdue visit to my best friend. For those that have been reading the newsletter long enough, you’ll remember that my best friend is a chiropractor in Amish country. There’s a longer story as to why he’s a chiropractor to the Amish, but he’s been so successful there, he built a house and lives there full time. It’s an amazing, slow-paced area and a great place to rest, recuperate, and build up energy for the busy weeks ahead.

The newsletter will definitely deliver next week, but I’m not 100% positive it will deliver the week of September 1st. I’ll know more next week and let you all know.

…

Many of you know I recently started the Must Learn AI Security series. The series is already up to Chapter 3 and is showing signs that readership will surpass the Must Learn KQL series.

With Chapter 3 on the wires, I’ve begun the process of updating and compiling the eBook version for each new chapter. So, the Must Learn AI Security eBook is now available and will now be updated when each new part in this series is released.

The book version (pdf) of this series is located here: https://github.com/rod-trent/OpenAISecurity/tree/main/Must_Learn/Book_Version

This is the permanent location of the book and when updated will get revisioning and timestamped, so you know you always have the most up to date edition.

…

Episode 2 of the new After the Blog podcast series is released. In it, my good friend Richard “Disney” Diver helps fill in some blanks from a recent blog post around using Microsoft Sentinel for things other than security purposes and if Content Filtering and Abuse Monitoring for AI is a component of Cybersecurity.

Listen here: Episode 2: Azure OpenAI Content Filtering and Abuse Monitoring with Microsoft Sentinel

…

That’s it for me for this week.

Thanks all for your continued support and love of Microsoft Security products!

Talk soon.

Microsoft defender for endpoint setup wizard ended prematurely because of an error - I have an issue where I am installing EDR on OS 2012R2 servers.

Microsoft Entra Things

How to Setup User Risk Reports to Email in Microsoft Entra - Evaluating the risk of a user in Microsoft Entra is something that Microsoft handles quite intelligently. For example, if a user reports a notification on the Microsoft Authenticator app as not being the one who requested it, their identity will be marked as high risk, as to get as far as an MFA notification, the correct password must have been entered. On the other hand, a series of unexpected actions on a user account could indicate malicious intent, which would result in a low-risk evaluation.
