USM Anywhere deploys the Google Cloud Platform (GCP) Sensor through the Google virtual private cloud (VPC) and requires at a minimum the specifications below:

Requirement	Description
n1-standard-2 instance	A standard instance with 2 vCPUs and 7.5 GB of memory
Zonal SSD persistent disk 50GB	Persistent disk storage offers reliable network storage that your instances can access like physical disks. A 50GB volume is designated as the default size for optimal performance.
Internet connection to the USM Anywhere secure cloud	Review the Sensor Ports and Connectivity for more information.

Application Service Dependencies

With the Deployment Manager Template provided by AT&T Cybersecurity, you can automatically deploy a USM Anywhere Sensor as a service into your environment. Review the following lists for information about the inbound and outbound IP addresses, ports, and services used by USM Anywhere.

Sensor Ports and Connectivity

For USM Anywhere Sensor deployment in the Google Cloud Platform (GCP), the Cloud Deployment Manager template automatically creates the firewall rules needed for network connectivity between the instances within the virtual private Cloud (VPC).

Note: The required firewall rules are outlined below.

Type	Ports	Inbound/Outbound	Endpoints	Purpose
TCP	443	Outbound	update.alienvault.cloud	Communication with AT&T Cybersecurity for initial setup and future updates of the Sensor
TCP	443	Outbound	reputation.alienvault.com	Ongoing communication with Open Threat Exchange® (OTX)
