Another blog to help expand Security Knowledge
Introduction Some exciting news! I have updated the “Export-AzSentinelMITREToCSV.ps1” file so that the individual rules can be saved to the CSV file instead of just the counts. This can be found in my GitHub repo here An older version of this can be found in the official Microsoft Sentinel GitHub repo located here. I am […]
Introduction When you perform a query and look at a table, for instance Heartbeat, in Microsoft Sentinel, you will see that the datetime fields are stored as UTC time zone values.

Overview Another Saturday, another blog post. In a completely unrelated note, I really miss Saturday morning cartoons 🙂 I was watching the latest Microsoft Security Insights show (Microsoft Security Insights Show Ep. 103 – YouTube) and saw some workbooks that Jing Nghik had created.

Overview This blog post will be slightly different than the ones I typically do as it is not technology driven. Rather this one will focus on describing a way of talking about security programs and the team that uses them. Security as a Car I was playing Forza Horizon 5 (very fun driving game) and […]
Overview In the last blog post, Recreating a MS workbook in PowerBI: Part 1 – Get the data – Yet Another Security Blog (garybushey.com), we looked at how to get data from Microsoft Sentinel into PowerBI. In this blog post, we are going to create the basic report that mimics the Microsoft Sentinel Security Operations […]
Introduction How many of you have come across a customer that says something along the lines of “We have this great program that we want you to interact with, but it has no API to access”. Maybe it is old, or maybe it was written in-house and adding an API was not considered a requirement. […]
“Microsoft Sentinel in Action” has been released! Technically it is the second edition of “Learn Azure Sentinel” but with all the changed that have occurred between the two books, it was almost a complete rewrite (of the technical sections at least).
