Log Analytics design - Defender for Cloud and Sentinel

All,

 

When you have Defender for Cloud and Sentinel.....do you still use 2 log analytics workspaces or do you reconfigure the defender for cloud log analytics workspace to ingest the defender for cloud events also into the sentinel workspace also?

 

best regards

 

Arjan

 

  • Arjan Veen, van one log analytics is good enough to you can forward the ASC(Azure security center/Defender alerts to  Sentinel . 

    Refer the below picture reference to one of the Microsoft source where it shows one log analytics is good enough for both Azure and On-prem

    Arjan Veen, van , it depends 😉.  Don't assume you can share a common LAW.  There are many factors to consider, such as ingestion of more than 100 GB/day, access control to the LAW, data sovereignty/geographic requirements, etc.  There is a decent decision tree at https://learn.microsoft.com/en-us/azure/sentinel/design-your-workspace-architecture#decision-tree

    They can happily share a workspace. There are lots of options, but typically I see one workspace.

        Hello,

        browse to defender for cloud - Environment settings - Auto provisioning - Extensions -Log Analytics agent/Azure Monitor agent - Edit Auto-provisioning configuration - Workspace selection and select the Sentinel workspace
