### Bicep or Terraform?

Bicep

### Module Classification?

I'm not sure, please advise

### Module Name

avm/ptn/security/sentinel

### Module Details

A module that will deploy Microsoft Sentinel and all its features (creating an analytic rule, playbook, data connectors, etc.) I know there's an [all in one](https://github.com/Azure/Azure-Sentinel/tree/master/Tools/Sentinel-All-In-One) but that's in JSON. Don't know if that can be supported, still learning Bicep.

### Do you want to be the owner of this module?

No

### Module Owner's GitHub Username (handle)

_No response_

### (Optional) Secondary Module Owner's GitHub Username (handle)

_No response_

Review the module indexes and the Microsoft Sentinel-All-In-One JSON linked in the proposal, then determine whether its analytic rules, playbooks, and data connectors can be represented in Bicep. Done requires an agreed module classification, defined scope, and an identified owner before implementation begins.
