Another blog to help expand Security Knowledge
Introduction I am sure you know that each Analytic rule in Microsoft Sentinel has a “Description field, and its contents get copied into the incident that this rule creates. I am sure you are also aware that some of the problems with newer security analysts are not knowing what steps to take to resolve an […]
Introduction Truth be told, I had this working a long time ago, it just took me way too long to figure out how to export the Logic Apps into working ARM templates! I am sure you know you can tag incidents after they are created. Wouldn’t it be great if you could do this automatically? […]
Introduction Edit: It appears that I forgot to put the actual link to the code. You can get it here If you do not keep up to date with the analytic rules, you may find yourself in the scenario where there are a lot of rules that have updates that can be applied. If you […]
Introduction In my last blog post (Extract Microsoft Sentinel MITRE information to CSV file – Yet Another Security Blog (garybushey.com)) I went over a PowerShell script that will extract the information from the MITRE ATT&CK page in Microsoft Sentinel. In this post I am expanding on that script with two new parameters ShowZeroSimulatedRuleTemplates ShowAllSimulatedRuleTemplates This […]
Introduction Microsoft Sentinel has a great MITRE ATT&CK page that shows you which tactics and techniques are being covered by your rules. It looks like the image below (this is from a new MS Sentinel instance, so I don’t have any rules enabled) It would be great to get this information into a CSV file […]
Introduction I have been asked quite a bit which API does Microsoft Sentinel do to perform X? That is usually followed up with how did I determine that? The answer to that question is very simple. I have delved into my previous life as a developer and used a tool that was incredibly useful when […]
Introduction There may be times when you have a complicated query that you use in your Microsoft Sentinel workbook that you want to re-use and only filter to show one specific row. Rather than re-running the query, I will show you how to use the “merge” data source in a query step to re-use the […]
Introduction This post is in response to a question that was asked on LinkedIn. The person wanted to know how to get the custom hunting queries using the REST API since it didn’t seem that any of the Microsoft Sentinel APIs retrieve that information. That is correct. There are no Microsoft Sentinel REST APIs to […]
Introduction One of the great new features in Microsoft Sentinel is the Content hub which allows you to search for, and activate, solutions. A solution is a self-contained offering inside of Microsoft Sentinel that can contain Data connectors, Analytic rules, Hunting Queries, Parsers, Playbooks, Workbooks, and/or Watchlists. I really hope that sometime in the future, […]
Introduction Did you know you can call a Microsoft Sentinel playbook from a workbook against an existing incident? It is actually quite easy to do, and this post will go into the details a bit more. ARM Actions One of the options available to use when you add a link to the “ARM Action” (currently […]
