Azure Ansible Misconfiguration: Improper Storage Account Network Access Control

YAML

Abstract

The Ansible task defines an Azure storage account with unrestricted network access.

Explanation

By default, Azure storage accounts created by Ansible accept connections from clients on any network.

Loose access configurations unnecessarily expose systems and broaden an organization's attack surface. Services open to interaction with the public are subjected to almost continuous scanning and probing by malicious entities.

Example 1: The following example Ansible task fails to restrict network access to an Azure storage account.


- name: storage with network acl
    azure_rm_storageaccount:
      resource_group: testGroup
      name: sa001
      type: Standard_RAGRS
      network_acls:
        bypass: AzureServices,Metrics
        default_action: Deny
        ip_rules:
          - value: 0.0.0.0/0
            action: Allow
