Another blog to help expand Security Knowledge
Introduction 19 Jan 2024 UPDATE: I have posted this same information (not quite as detailed) in the Microsoft Sentinel blog at Querying Watchlists – Microsoft Community Hub however, it does have a section on “bag_unpack” and the best way to use it. As I am sure you already know, you can get the entries from […]
I have finally finished the first version of my “Programming Microsoft Sentinel using REST APIs” EBook is ready to go. You can download it from: garybushey/ProgrammingMicrosoftSentinel: Programming Microsoft Sentinel book (github.com) Let me know what you think. Can you easily follow it? Are the examples (both in the descriptions and use cases) useful and easy […]
Introduction I am working on a book on how to use the Microsoft Sentinel REST APIs to perform your tasks. Rather than dealing with the hassle of a publisher, I am following in Rod Trent’s footsteps and writing it as a word document which will be released as a PDF. Time (and interest) permitting, I […]
You may have noticed that when you go into your Microsoft Sentinel Analytic rule templates area, you will see a banner like the one shown below: What does this mean? Basically, Microsoft Sentinel is not going to deploy all the Analytic rule templates (as well as Workbook templates, hunting queries, and data connectors) when a […]
Introduction Just over three years ago I wrote a blog post and code about how to create multiple rules from Microsoft Sentinel analytic rule template. A lot has changed in that three years. Not only have new features been added to Microsoft Sentinel, but I have learned better ways to work with PowerShell. With all […]
Introduction I have heard from many people that they would like to be able to see which rules need to be updated. There is currently no easy way to do this in the Microsoft Sentinel portal. You can go through each page and see which ones have the “Update Available” tag in the name, but […]
Introduction I recall reading a post where someone asked if there was a way to generate a word document when an incident was closed for reporting purposes. There is no built-in way, but by using a Playbook, a Team’s site (or other SharePoint site), and a Word template, you can do this. The Playbook, Word […]
Introduction One last post for 2022! Microsoft Sentinel has the Content Hub which, at the time this post was written, is still in preview. Inside the Content Hub are two types of entries: Solutions and Standalone contents. Standalone contents are pretty new and are just single entities that can be enabled and be listed using […]
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. While there are exceptions to this rule, the TimeGenerated will always be stored using the UTC time zone. This can be both a blessing […]
