I am planning to enable SCIM provisioning for my Azure Databricks resource. It is mentioned in the MS Doc that it is always recommended to enable SCIM at the account level and not at the individual workspace level
So now if i enable SCIM provisioning for Databricks at the account level and register an application in Azure AD how do i give access to various groups to individual workspaces
Say i create a group --> "Finance-Admin" and add this group to the Azure AD application, then members belonging to this group will get access to Databricks.
But what if i want to create two groups, "Finance-Admin" and another "Finance-Users"
Now i want to give "Finance-Admin" users permission to the Finance workspace so that they can create clusters and add node pools
For the users for the "Finance-Users" group i want to only give permission to restart clusters in Finance workspace
So how do i do these things if i am using Terraform to provision clusters and provide cluster permissions also using IaC
Is this achievable with SCIM provisioning at the account level or whatever i am trying to achieve i need to do SCIM provisioning at the Workspace level ?
Yes, it's possible to do that using account-level SCIM synchronization - SCIM connector will sync groups and users into the Account Console, and then you can assign groups to the specific workspaces. With Databricks Terraform provider account-level users/groups are assigned to workspaces using the mws_permission_assignment resource.

Currently, I am working on establishing enterprise-scale landing zones for Cloud Adoption Framework in Azure.
Azure has a list of BuiltInRoles defined as mentioned in this article - https://learn.microsoft.com/en-us/azure/role-based-access-control/built-in-roles.
It is unclear to me which role should be assigned to which resource
Especially for the below Resources
Management Groups
Subscriptions
Vnets
Gateways,
VMs
Storage Accounts,
SQL databases
Can you suggest what are all the Roles should be assigned while provisioning any of the above listed Resources?
The Cloud Adoption framework is not about putting some roles on some arbitrary resources. You have to look at the framework in terms of hierarchical levels. Each hierarchical level has its own purpose and therefore uses its own set of permissions to deploy the resources needed for that particular step. I referenced some role mapping templates from aztfmod (Terraform + CAF) so that you get an idea about the role/permission structure.
Level 0: Core platform automation
Billing subscription role delegation (source)
Credential role mappings (source)
Launchpad role mappings (source)
Level 1: Core platform governance
Level 2: Core platform connectivity
ASVM role mappings (source)
Level 3: Application landing zones vending machine
Level 4: Applications landing zone
If you understand the levels correctly, you are able to infer what permissions are needed at what stage of the deployment of the CAF framework. For example:
level 0 is initiated by a user that is tenant administrator and Enterprise Agreement (EA) user, besides it needs to be the owner of the initial "launchpad" subscription.
From there this user will create service principals for each of the other stages of the deployment, and delegate permissions according to the principle of least privilege.
Key vaults and key vault policies are used to exchange sensitive information like credentials in between steps.
Each platform step (automation, governance, connectivity) is then run by its own service principal with its own specific set of permissions set on a specific scope (management group, subscription, resource group).
When all the platform components are in place you’ll be able to provision custom landing zones. Where you’ll again create service principals that are scoped to a single subscription. These service principals are able to deploy resources only within that landing zone.
Etc.
I would not recommend setting CAF or the permissions by hand, because it will become a pain in the ass to maintain. You could for example use aztfmod a Terraform implementation of CAF. If you follow the steps as described here, you'll create terraform configuration to deploy a CAF setup.
I am currently trying to work out a concept for a roles and rights concept. Azure RBAC already has a few built-in roles but I am trying to create a few more custom roles. Are custom roles directly linked to the RBAC? And does anyone have any suggestions which roles I should definitely add? I'm not familiar with all applications in Azure at the moment since i have only been working with azure for a few weeks, so I would appreciate some suggestions. I am also trying to understand the hierarchy and structure behind Azure RBAC.
If anyone has worked out such a concept themselves or works a lot with azure rbac, feel free to share your experiences or results!
Azure role-based access control (Azure RBAC) helps manage who has access to Azure resources, what they can do with those resources, and what areas they have access to.
Azure RBAC is an authorization system built on Azure Resource Manager that provides fine-grained access management of Azure resources.
Create your own custom roles. Just like built-in roles, assign custom roles to users, groups, and service principals at management group (in preview only), subscription, and resource group scopes.
Custom roles can be shared between subscriptions that trust the same Azure AD directory. There is a limit of 5,000 custom roles per directory. Custom roles can be created using the Azure portal, Azure PowerShell, Azure CLI, or the REST API.
At the moment most users are given default roles in Azure such as Contributor or User. We need to prevent this and only allow users to be added only in AD groups. And these groups need to be provided Azure access(IAM). I am thinking of using Azure Policy for this. But cannot find any documentation in this regard.
Unfortunately, as of today (Oct 20, 2020), I do not believe this is possible with policy. It is my understanding that Azure Policy intentionally draws a distinct line between Azure Resources and anything Azure Active Directory or RBAC related. Azure Policy is meant to be agnostic of roles and users with an exception to the roles required to perform a remediation in deployIfNotExists policies.

I am currently in the process of setting up Sentinel POC, within Sentinel you have playbooks which is basically Logic Apps, it is same as the playbooks in security center.
I need to know what permissions i need on target subscriptions in order to automate remediation of alerts, for example isolate a VM, Stop a VM, etc.
Our Sentinel will have its own subscription in a tenant where there are 100's of subscriptions.
Its best to use a service principal for having centralized access control.
With this, you can use the service principal to authenticate and authorize actions against resources. It can be configured for the Azure Resource Manager connector in Logic Apps as well.
Another option would be to use Managed Identity, but that is supported only for the HTTP Action.
As for the exact permissions for this service principal / managed identity, you can use this reference of built-in roles for providing granular control. For example, to just stop/start VMs, your service principal would need Virtual Machine Contributor.
You could also provision finer access to resources by creating custom roles.
I would need to create a policy in subscription level contributor cannot able to create virtual machines and virtual network or any vnets. Only owner are able to create Vnets. How to do this
It looks like you might need to create a custom role.
You can add various roles using RBAC for Access management of cloud resources.
The following document has the information on all the built-in roles in Azure RBAC:
https://learn.microsoft.com/en-us/azure/role-based-access-control/built-in-roles
If built-in roles do not fulfill your requirements, you can also use create your own custom roles using PowerShell:
