Set default values to a secure value - Azure Kubernetes Services

[elbatane]

All default values should comply with a security baseline, e.g. NIST 800

The build-in policies of Azure can be used as a reference.

The task would be to scan over each of the following policies and make sure, that the module is per default complying to them.

The following policies are the NIST 800 ones:

• \built-in-policies\policyDefinitions\Kubernetes\AKS_AzurePolicyAddOn_Audit.json
• \built-in-policies\policyDefinitions\Kubernetes\AKS_CMK_Deny.json
• \built-in-policies\policyDefinitions\Kubernetes\AKS_EncryptionAtHost_Deny.json
• \built-in-policies\policyDefinitions\Kubernetes\AllowedHostPaths.json
  • Cluster internal?
• \built-in-policies\policyDefinitions\Kubernetes\AllowedUsersGroups.json
  • Cluster internal?
• \built-in-policies\policyDefinitions\Kubernetes\ASC_Azure_Defender_Kubernetes_Arc_Extension_Audit.json
  • On-Premise?

I guess most policies can be ignored as they require deployments onto the cluster?
