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. There is the functionality for analytic rules, but it is not yet there for automation rules. I had some simple PowerShell scripts that […]
Introduction Update: Microsoft Sentinel now has the ability to trigger a playbook when an incident has been updated so this blog post is obsolete! If you are like me, you feel that one of the holes in Microsoft Sentinel is knowing when something changes. I am hoping that this changes soon (pun intended). In the […]
If you have read either version of my book, I sent you to a URL that uses the Azure Data Explorer to play around with the KQL queries. Rod Trent just posted a blog at Create and Maintain Your Own KQL Demo Environment with the New Start-for-free Cluster – Azure Cloud & AI Domain Blog […]
Introduction As you probably already know, Jupyter notebooks allow for much great threat hunting than you can get using the OOTB Azure Sentinel Threat Hunting queries, especially when you consider that you can run the Azure Sentinel KQL queries from a Jupyter notebook. Most of the articles written about Azure Sentinel and Jupyter notebooks use […]
While looking at the SigninLogs table in Azure Sentinel I noticed there are a lot of dynamic fields that hold JSON data. I was trying to use parse_json to get to the data but it was always returning empty fields. I then realized that parse_json requires a string input, not a dynamic. After some messing […]
Introduction If you go into the Azure Sentinel Logs page you can get a listing of all the tables that you have as well as the individual columns that make up the tables. Wouldn’t it be great if you could export that list into a CSV file? With the use of Azure Sentinel’s REST API […]
Could this mean that an announcement of support Azure Sentinel REST API is coming soon? Let’s hope so! Take a look: https://github.com/Azure/azure-rest-api-specs/tree/master/specification/securityinsights/resource-manager/Microsoft.SecurityInsights
I was playing around with workbooks and noticed that there is a new preview Data Source called Azure Resource Manager. When I selected it I noticed that the Path it wanted begins with /subscription so I thought I would try it with the URL to get Incidents from Sentinel. Lo and behold it worked! It […]
I was looking the latest changes MS made to the Azure Sentinel REST API (available at https://github.com/Azure/azure-rest-api-specs/tree/master/specification/securityinsights/resource-manager/Microsoft.SecurityInsights/preview/2019-01-01-preview) and noticed that they now have an entire section called “incidents” that can be used just as “cases” could before. This makes more sense since, during the beta, Alerts created “cases” but now they create “incidents” . This […]
Introduction IMHO, one of the biggest PITA when setting up a new instance of Azure Sentinel is that while Microsoft gives you all these great Analytic rule templates, you have to select each, one at a time, to create a rule from them. These PowerShell scripts will avoid that. First, there is a PowerShell command, […]
