![]() The last part is to configure the Logic App to then push that data to Azure Sentinel which we do with three quick actions. Now each time a detection is created in CrowdStrike Falcon it will send the data to our Logic App. Grab that address then head over to CrowdStrike and create your notification workflow, which is a simple process outlined here. On the Azure Sentinel side we first create a new Logic App with the ‘When a HTTP request is received’ trigger, once you save it you will be given your webhook URL. Overview of Fusion Detections Fusion detections using. Hopefully you don’t get too many detections, so this data will basically cost nothing. in ML within many services, including ASC and Azure Sentinel. So for CrowdStrike, in this example, we are just going to send a webhook to Sentinel each time a detection is found, then ingest that into a custom table using a simple Logic App so we can expand our hunting. What we can do though is send some low volume, but high quality data into Sentinel to jump start further investigations or automations based on other data we have in there – the logs from Defender for Endpoint in passive mode, the SecurityAlert table from things like Azure Security Center or Defender for ID, Azure AD sign in logs etc. So if you are paying for a non Microsoft product like CrowdStrike or Carbon Black, you probably don’t want to send all the data from those products to Azure Sentinel as well, because a) you are paying for that privilege with your endpoint security vendor already, b) that product may either be managed by the vendor themselves, a partner and/or c) even if you manage it yourself, the quality of the native tooling in those products is part of the reason you pay the money for it and it doesn’t make a lot of sense to lift every event out of there, into Sentinel and try and recreate the wheel. (Optional Step) Securely store workspace and API authorization key (s) or token (s) in Azure Key Vault. Check the Azure Functions pricing page for details. This might result in additional data ingestion costs. Defender for Endpoint now happily sits behind other products in ‘passive mode’, like CrowdStrike Falcon, while still sending great data and integrating into apps like Cloud App Security, you can connect M365 to Sentinel with a native connector. This connector uses Azure Functions to connect to the SentinelOne API to pull its logs into Microsoft Sentinel. Thankfully times change, due to a combination of smarter endpoint security products, more powerful computers and a willingness of Microsoft to work along side other vendors, that is no longer the case. The thought of running multiple antivirus products on an endpoint was outrageous, and basically every vendor told you explicitly not to do it. Third party app not working, more exclusions. Server running slow, put in a heap of exclusions. Remember when antivirus software was the cause of every problem on devices? Workstation running slow? Disable AV.
