USM Anywhere™

Requirements for AWS Sensor Deployment

USM Anywhere deploys the Amazon Web Services (AWS) Sensor in the Amazon Elastic Compute Cloud (EC2) platform through the Amazon Virtual Private Cloud (VPC).

Requirement Description
m5.large instance An m5.large instance in an Amazon VPC.

100GB EBS volume

The Amazon Elastic Block Store (EBS) provides short-term storage for your data as it is processed.

A 100GB Amazon EBS volume is designated as the default size for optimal performance.

Internet connection to the USM Anywhere secure cloud Review the Sensor Port and Connectivity on this page for more information.

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.

Note: Support for AWS classic sensor has been deprecated. Only VPC deployments are supported.

AWS Sensor Deployment Regions

The AWS Sensor is deployed in one of the AWS endpoint regions based on your location. The following table lists the code and name of each region.

Important: The Update Server and the AlienVault Agent always use the 3.235.189.112/28 range no matter where your USM Anywhere is deployed. The AT&T TDR for Gov Update Server uses the 3.32.190.224/28 range.

AWS Regions for AWS Sensor Deployment

ap-northeast-2 Asia Pacific (Seoul)
ap-south-1 Asia Pacific (Mumbai)
ap-southeast-1 Asia Pacific (Singapore)
ap-southeast-2 Asia Pacific (Sydney)

sa-east-1 South America (São Paulo)
us-east-1 US East (N. Virginia)
us-east-2 US East (Ohio)
us-west-1 US West (N. California)
us-west-2 US West (Oregon)

Note: Though your sensor is deployed to one region, it will monitor all regions, pulling assets, logs, and other data regardless of region.

Application Service Dependencies

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

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)
Type Ports Endpoints Purpose
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.

See Troubleshooting and Remote Sensor Support for more information about remote technical support through the USM Anywhere Sensor console.

Important: A USM Anywhere Sensor deployed in AWS might require outbound access to specific AWS resources, based on the sensor app in use. For example, the AWS Sensor app must have the ability to connect to the AWS API (port 443). However, the actual API endpoint might be different depending on the service (such as Amazon Simple Storage Service [S3] or Amazon CloudWatch).

USM Anywhere normally gives systems explicit access to the AWS API.

Sensor Ports and Connectivity (Inbound Ports)
Type Ports Purpose
SSH 22 Inbound method for secure remote login from a computer to USM Anywhere.
HTTP 80 Inbound communication for HTTP traffic.
UDP (RFC 3164) 514 USM Anywhere collects data through syslog over UDP on port 514 by default.
TCP (RFC 3164) 601 Inbound communication for reliable syslog service. USM Anywhere collects data through syslog over TCP on port 601 by default.
TCP (RFC 5424) 602 USM Anywhere collects data through syslog over TCP on port 602 by default.
Traffic Mirroring 4789 Inbound communication for virtual extensible local area network (VXLAN).
TLS/TCP (RFC 3164) 6514 USM Anywhere collects Transport Layer Security (TLS)-encrypted data through syslog over TCP on port 6514 by default.
TLS (RFC 5424) 6515 USM Anywhere collects data through syslog over TLS on port 6515 by default.
Graylog 12201 Inbound communication for Graylog Extended Log Format (GELF).

Security Groups in Your AWS VPC

For sensor deployment in an AWS VPC, the AWS CloudFormation template automatically creates the security groups needed for network connectivity between the instances within the VPC. However, this does require that you manually assign the USMServicesSG security group to your hosts to enable access to the UDP port 514 so that the sensor can receive syslog packet transmissions.

See Enable Connections in an AWS VPC for more detailed information about these security groups.

AWS Services

USM Anywhere uses the following AWS services:

  • Amazon CloudWatch
  • AWS CloudTrail
  • AWS Elastic Load Balancing (ELB)
  • Amazon Simple Storage Service (S3)
  • Amazon EC2
  • AWS Identity and Access Management (IAM)
  • Amazon GuardDuty
  • Amazon Relational Database Service (RDS)

See IAM Roles and Permissions Required by Your AWS Sensor for a full description of the IAM roles and permissions that your AWS Sensor requires for these AWS services.

Note: USM Anywhere uses us-east-1 as a default region in the amazon-aws app. As a result, you might want to verify whether your Sensors are communicating with us-east-1, even if you have never deployed to that region.

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.

Important: The Update Server and the AlienVault Agent always use the 3.235.189.112/28 range no matter where your USM Anywhere is deployed. The AT&T TDR for Gov Update Server uses the 3.32.190.224/28 range.

Installation Prerequisites

Before you install the AWS Sensor, make sure you have the following prerequisites available.

Installation Prerequisites
Prerequisites Description
AWS CloudFormation template provided by AT&T Cybersecurity

The AWS CloudFormation template automatically creates all required AWS resources for deployment, including an IAM role and instance profile for use by the USM Anywhere Sensor instance.

URLs for these templates are included in the Deploy the AWS Sensor instructions.

Privileged user account on AWS To deploy the AWS CloudFormation template, you must have a privileged user account in AWS with permissions to create IAM resources.

Multiple AWS Accounts or Amazon VPCs

If you have multiple AWS accounts, you must deploy the AWS Sensor in each AWS account that you want to monitor.

Amazon VPC enables you to launch AWS resources into a virtual network that you've defined. A single sensor can monitor an entire AWS account, even when it contains multiple Amazon VPCs.

Note: If you intend to use the USM Anywhere vulnerability A known issue or weakness in a system, procedure, internal control, software package, or hardware that could be used to compromise security. scanner with the AWS Sensor, you must allow traffic from the sensor and the target instance you are scanning. You can usually accomplish this by using Amazon VPC peering (see the AWS documentation for more information).
