Deploying collateral from our GitHub repository to your Azure Sentinel instance is very similar in that it is a copy/paste operation. This guidance is specific to an Analytics Rule.
P.S. There’s automated ways to accomplish this, but it’s also a good thing to know for basic understanding. For an automated way, see Wortell’s PowerShell module: AZSentinel/AzSentinel at master · wortell/AZSentinel (github.com)
How to do it
Analytics Rules are located in the Detections folder of the GitHub repo. Locate an Analytics Rule you want in the GitHub Repo. Click the “Raw” button on the page to “sanitize” the code. Sanitizing code ensures there’s no hidden characters or bad formatting.
