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 […]
I am happy to announce that the book I have been writing with my co-worker, Richard Diver, (and I have no idea how he got top billing 😉 ) is almost finished and will be released soon. It is an introduction to Azure Sentinel and covers all the topics from planning your Log Analytics workspace […]
Microsoft quietly released the Incident settings page in the Scheduled Analytics rule wizard. On this page you can state whether you want the alert to create an incident, if the alerts should be grouped into a single alert, and if you want to re-open closed incidents when a new alert is generated. The page looks […]
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, […]
Introduction I was recently asked how an Azure Sentinel Playbook could update the owner of an Incident automatically. Well, there are two issues with that: Only Scheduled rules can trigger Playbooks (at least right now. <hint>, <hint> Microsoft!). You can however run the Playbook from the Incident’s Full Details page using the Alert tab. The […]
Introduction Microsoft is making great strides and making Azure Sentinel one of the best SIEM products out there. One way they do this is to allow other Azure security products to forward their alerts into Azure Sentinel to make a one-stop-shop kind of experience. While this is great, one feature that, IMHO, is lacking is […]
Introduction When I was writing my blog post about downloading the Azure Sentinel Incidents, I got to thinking about what else could you do with them? As I had been working with PowerBI I thought, why not give that a shot? I would rather have these show up in an Azure Sentinel Workbook but, so […]
