AlienVault® USM Anywhere™

Requirements for Azure Sensor Deployment

To ensure that you can successfully deploy USM Anywhere in your Azure subscription and monitor all of your Azure resources, make sure you have the following available in your Azure environment:

  • An Azure account with privileges in the resource group or subscriptions that you want to install the USM Anywhere Sensor

    Note: You can deploy a single USM Anywhere Sensor to monitor all of your Azure resource groups. To do this, you must assign the application you create to the entire subscription.

  • Administrative access to Active Directory within Azure

    This Active DirectoryActive Directory (AD) is a directory service that Microsoft developed for Windows domain networks. access allows you to create an application required to install resource groups or a subscription for monitoring.

  • A virtual network inside the resource group
  • A subnet inside the virtual network
  • A storage account

Important: USM Anywhere does not support Azure Classic accounts.

Sensor Ports and Connectivity

Before you deploy a USM Anywhere Sensor, you must configure your firewallVirtual or physical device designed to defend against unauthorized access to data, resources, or a private network. A firewall’s primary purpose is to create segregation between two or more network resources, blocking undesirable traffic between them. permissions to enable the required connectivity for the new sensor. Initial deployment of a sensor requires that you open egress and outbound ports and protocols in the firewall for communication with USM Anywhere and AT&T Cybersecurity Secure Cloud resources. The sensor receives no inbound connections from outside the firewall.

Note: To launch the USM Anywhere Sensor web user interface (UI) during the initial setup, you need to allow inbound traffic to the sensor IP address through TCP port 80. You can remove access to this port after the sensor successfully connects to USM Anywhere. You do not need to allow inbound traffic to this port from the Internet.
