USM Anywhere deploys the Amazon Web Services (AWS) Sensor in the Amazon Elastic Compute Cloud (EC2) platform through the Amazon Virtual Private Cloud (VPC) and requires the following specifications:
  • An m5.large instance in an Amazon VPC.
  • A 100 GB Amazon EBS /data volume.
    Note: A 100 GB Amazon EBS /data volume is designated as the default size for optimal performance. The Amazon Elastic Block Store (EBS) provides short-term storage for your data as it is processed.
  • Internet connection to the LevelBlue Secure Cloud. See Sensor Ports and Connectivity for more information.
  • Zonal SSD persistent disks.
    Note: Persistent disk storage offers reliable network storage that your instances can access like physical disks. For optimal performance, 50 GB and 128 GB volumes are designated as the default size for the root and data partitions.
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) a sensor can process varies.Depending on your environment, you may need to deploy additional sensors to ensure that all events are processed.

​
WS 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 LevelBlue TDR for Gov Update Server uses the 3.32.190.224/28 range.
AWS Regions for AWS Sensor Deployment
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 LevelBlue, 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 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)
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 differ 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.

​
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 Allowlisting

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 LevelBlue TDR for Gov Update Server uses the 3.32.190.224/28 range.
Note: The regional IP ranges listed in this table are limited to the control nodes (subdomain). You must also meet all requirements provided in the Sensor Ports and Connectivity (Outbound Ports) table.

Installation Prerequisites

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

​
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 have 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 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).
