Requirements for GCP Sensor Deployment

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

Google Cloud Services

The USM Anywhere Sensor uses the following GCP services:

  • Stackdriver
  • Google Compute Engine
  • Google Cloud Pub/Sub

Installation Prerequisites

Before you install the GCP Sensor, make sure you have the following prerequisites available:

Prerequisites Description
Cloud Deployment Manager template provided by AT&T Cybersecurity

The Deployment Manager template automatically creates all required GCP resources for deployment, including an instance, volume, and firewall rules for use by the USM Anywhere Sensor instance.

Privileged user account on GCP To deploy the Deployment Manager template, you must have a privileged user account in GCP with Compute Engine permissions, permission to create and edit service accounts, as well as write permission to the Deployment Manager.
