Requirements for USM Anywhere Sensor Deployment on Azure

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 in which 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

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.

Note: Initial deployment of a USM Anywhere Sensor requires that you open egress/outbound ports and protocols in the firewall for communication with USM Anywhere and AlienVault cloud resources. After the initial sensor setup, you do not need to open any external inbound ports because the USM Anywhere Sensor receives no inbound connections from outside the firewall.

Type Ports Endpoints Purpose
TCP 80 Communication from the Sensor to the USM Anywhere environment, and from AlienVault for initial setup of the Sensor

Important: Both ingress and egress are required for the initial setup of the Sensor. After the Sensor is connected, you can close all ingress for this port.

TCP 443 Communication with AlienVault for initial setup and future updates of the Sensor
TCP 443 Ongoing communication with Open Threat Exchange®
TCP 443 your USM Anywhere subdomain
Ongoing communication with USM Anywhere
SSL / TCP 7100 your USM Anywhere subdomain
Ongoing communication with USM Anywhere
UDP 123

Synch with NTP services in the AlienVault cloud

We also recommend that you configure outbound connectivity for port 22 and 443 to to support SSHProgram to securely log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another through SCP. communications with the USM Anywhere Remote Support server.
