Thank you for your post and I apologize for the delayed response!

I understand that you're trying to change the Security events storage configuration from None to All Events, but the option is greyed out even though you have the correct permissions. To hopefully help point you in the right direction or resolve your issue, I'll share my findings below.

Findings:

When it comes to changing the Security events storage configuration, I was able to reproduce your issue and to change my Security events storage configuration from None to All Events, I had to:

1. Navigate to Defender for Cloud, select Environment settings.
2. Select the relevant workspace.

Note: If you configured the Security Events within Azure Sentinel to change the tier, you'll need to do this in Azure Sentinel, and it will apply for Microsoft Defender for Cloud.

Additional Links:

• Setting the security event option at the workspace level
• Configure the Log Analytics agent and workspaces
• Windows security event options for the Log Analytics agent
• How can I use my existing Log Analytics workspace?

I hope this helps!

If you have any other questions, please let me know. Thank you for your time and patience throughout this issue.

Hi, Thanks for asking your question! When you autoprovision the Log Analytics agent in Defender for Cloud, you can choose to collect other security events to the workspace. When you autoprovision the Azure Monitor agent in Defender for Cloud, the option to collect other security events to the workspace isn't available. Defender for Cloud doesn't rely on these security events, but they can be helpful for investigations through Microsoft Sentinel.

If you want to collect security events when you autoprovision the Azure Monitor Agent, you can create a Data Collection Rule to collect the required events. So the option will remain grayed out Here is the reference: https://learn.microsoft.com/en-us/azure/defender-for-cloud/auto-deploy-azure-monitoring-agent#deploy-the-azure-monitor-agent-with-defender-for-cloud .
