Storage - Add storage firewall rulesΒΆ

Finds storage accounts with no ip rules and modifies them to: - Deny public access - Enable Logging and Metrics access to the database - Allow access from the locations specified by ip-rules and virtual-network-rules

policies:
    - name: add-storage-firewall

        Find storage accounts without open ip list and restrict them.

Finds storage acocunt with no ip rules and modifies it to: - Enable Logging and Metrics access to the database - Allow access from the location specified by ip-rules

Note: Because this policy leaves the storage account open to access by all ip addresses, the new rules will have no effect on the performance until the default-action is set to Deny.
