USM Anywhere™

Requirements for VMware Sensor Deployment

Review the following prerequisites to ensure an efficient setup and configuration of the USM Anywhere Sensor on VMware.

Minimum Requirements

These are the minimum requirements to set up and configure the USM Anywhere Sensor on VMware:

  • Access to VMware ESXi 6.5 or later, including the free version.
  • Dedicated 4 CPUs and 12 GB of reserved memory.
  • Dedicated 150 GB of disk space (100 GB data device and 50 GB root device).
  • Internet connectivity to the network where you plan to install the VMware Sensor.

Important: Because the needs of a sensor differ based on the varying demands of different deployment environments and the complexity of events being processed, the number of events per second (EPS) throughput a sensor can process varies.

Depending on your environment, you may need to deploy additional sensors to ensure that all events are processed.

Recommended Requirements

These are the recommended requirements to set up and configure the USM Anywhere Sensor on VMware:

  • A VMware vSphere or VMware vCenter user account to use for USM Anywhere Sensor configuration with an assigned role that has permissions equivalent to the read-only default role.

    Note: The read-only role enables a user limited read access to the system without any other privileges. Credentials with this assigned role enable the deployed USM Anywhere Sensor to collect vCenter and vSphere events and run asset discovery.

  • Installed VMware Tools for hosts in your vSphere or vCenter environment.

    With configured vSphere or vCenter credentials, the VMware Sensor uses the VMware APIs to run asset discovery. For hosts that do not have VMware Tools installed, the asset does not have an assigned IP address and this can result in the asset being missed from asset discovery or in duplicate assets created during subsequent discoveries. These tools also enable the sensor to collect more detailed information about the asset.

  • If Dynamic Host Configuration Protocol (DHCPNetwork protocol used to dynamically distribute network configuration parameters, such as IP addresses, for interfaces and services.) is not available, a configured static IP for the management interface and local Domain Name System (DNS) information.

    Important: AT&T Cybersecurity strongly recommends assigning a static IP address to deploy the USM Anywhere Sensor. If DHCP changes the IP address of the sensor, you must update all the IP addresses on all the devices that are forwarding logs to the sensor through syslog.

  • Port mirroringMethod of network monitoring in which a system passively collects network traffic on the same ports as other network devices. set up for network monitoring (see Direct Traffic from Your Physical Network to the VMware Sensor for more information).
  • Administrative credentials for devices that require configuration to forward logs to the VMware Sensor.
  • Administrative credentials for remote hosts to support authenticated asset scans.
  • Configuration on firewall or other security device to send UDP or TCP syslog (if it is capable of exporting security logs through UDP or TCP syslog).
  • Network topology information to run asset discovery.
  • To access network-based intrusion detection system (NIDS) functionality on the sensor, an ethernet port on the host must be available to receive data from a Switched Port Analyzer (SPAN) or Test Access Point (TAP) port.

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.

The following tables list the inbound and outbound ports.

Sensor Ports and Connectivity (Outbound Ports)

TCP 443 update.alienvault.cloud Communication with AT&T Cybersecurity for initial setup and future updates of the sensor.
TCP 443 reputation.alienvault.com Ongoing communication with AT&T Alien Labs™ Open Threat Exchange® (OTX™).
TCP 443 otx.alienvault.com

Ongoing communication with OTX to retrieve vulnerability scores. Connecting to otx.alienvault.com is not required but highly recommended.

OTX uses the AWS Cloudfront services. Refer to the AWS IP address ranges page when you deploy a new sensor. This page contains the current IP address ranges for the service and for instructions on how to filter the addresses.

USM Anywhere IP Addresses for Whitelisting

Your sensor is connected to a USM Anywhere instance deployed in one of the Amazon Web Services (AWS) endpoint regions based on your location. If you need to configure your firewall to allow communication between the sensor and the USM Anywhere instance, refer to the following table with the reserved IP address ranges for each region.
