Introduction Much of the investigative work done inside of Microsoft Sentinel, as well as many other Azure products that use KQL, deals with IP Addresses. Matching, comparing, and seeing if they show up in a table are many of the actions we perform against IP Addresses. Luckily, KQL provides many different functions to work with […]
Introduction Ok, the title is a bit cheesy, but the song just came on and it really does fit. Anyone who has used KQL for any length of time knows about the “datetime”, “now”, and “ago” command as in To see information in the last 5 days. However, KQL provides a lot more capabilities regarding […]
Introduction I ran across a question where someone was asking how to extract Microsoft Sentinel automation rules. I had thought the functionality was already in the automation rules, but I was wrong.

Overview Back in the first post in this series, I mentioned that you can easily change how far back you can look to get information in your queries. This post will talk about PowerBI parameters that we will use to do this. Create a parameter Parameters are very easy to create. In left hand navigation […]
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 So far in this series (if 3 posts can be considered a series), we have ingested data into PowerBI and created a basic report. We looked at some of the pitfalls that may happen when creating a table view. In this post, we will look at the tables themselves and how we can expand […]
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 […]
