Description
Just in time (JIT) virtual machine access can be used to lock down inbound traffic to Azure VMs, reducing exposure to attacks while providing easy access to connect to VMs when needed.
How to fix?
Set policy_definition_id to /providers/Microsoft.Authorization/policyDefinitions/b0f33259-77d7-4c9e-aac6-3aabcfae693c and enforcementMode to Default.
Example Configuration
{
"$schema": "https://schema.management.azure.com/schemas/2018-05-01/subscriptionDeploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"resources": [
{

"policyDefinitionId": "/providers/Microsoft.Authorization/policyDefinitions/b0f33259-77d7-4c9e-aac6-3aabcfae693c"
}

}
Set policy_definition_id to /providers/Microsoft.Authorization/policyDefinitions/b0f33259-77d7-4c9e-aac6-3aabcfae693c, and set enforce to true or remove the attribute.

policy_definition_id = "/providers/Microsoft.Authorization/policyDefinitions/b0f33259-77d7-4c9e-aac6-3aabcfae693c"
