Complete the AWS Sensor Setup

The Network Security Monitoring page shows the status of the network interfaces monitored by the sensor (it could take a few moments to load the interfaces). All network adapters are configured for network monitoring by default.

You must manually enable port mirroring or port spanning Method of network monitoring in which a system passively collects network traffic on the same ports as other network devices., promiscuous mode Mode in which network IDS monitoring operates in passive listening mode, checking all IP packet traffic passing through it for threats., or both in a virtual switch to send a copy of the network traffic you want to analyze to these interfaces. This page provides links to documentation about how to configure your networking to allow for the interfaces to see the network traffic and perform network intrusion detection.

USM Anywhere connectivity and communications are handled by the first network interface connection on the Network Security Monitoring page. This is the primary network that provides asset scanning and log collection for the particular network.

You can connect additional interfaces to other networks for monitoring, or connect them to individual vSwitch port groups for virtual networks. Each interface should be connected to a vSwitch that mirrors a different subnet within your network.

Use this page to verify that USM Anywhere can monitor your network traffic for security events.

To access detailed information about virtual private cloud (VPC) traffic mirroring

1. Click How do I set up VPC traffic mirroring?

   This opens a dialog box.

   

   If you have not yet set up VPC traffic mirroring, see VPC Traffic Mirroring with an AWS Sensor for more information.

2. Click Next.

USM Anywhere automatically discovers several of out-of-box logs as long as you have enabled them within your Amazon Web Services (AWS) subscription. See AWS Log Discovery and Collection in USM Anywhere for more information about these logs and how they function within the AWS environment.

To enable the Amazon Simple Storage Service (S3) and Amazon CloudWatch out-of-box log collection jobs

1. Locate the jobs you want to enable and click the icon.
   This turns the icon green ().

   

   Note: You can also enable AWS CloudTrail logs, Amazon Elastic Load Balancing (ELB) access logs, and other security logs. However, make sure you've enabled these first on your AWS account.

2. Click Next.

On the Log Management page are syslog port numbers. (These ports are the same for all USM Anywhere Sensors.)

USM Anywhere collects third-party device, system, and application data through syslog An industry standard message logging system that is used on many devices and platforms. over UDP on port 514 and over TCP on ports 601 or 602 by default. It collects Transport Layer Security (TLS)-encrypted Transport layer security. Successor to Secure Sockets Layer (SSL) protocol. Provides security for communication over the Internet between client and server applications. data through TCP on ports 6514 or 6515 by default. These ports support the RFC 3164 and RFC 5424 formats. To configure any third-party devices to send data to USM Anywhere, you must provide the IP address and the port number of your USM Anywhere Sensor.

To enable log collection and configure your log management

1. Make sure that you have granted the necessary permissions for your OS to allow USM Anywhere to access its logs. You can also integrate a wide variety of data sources to send log data over syslog to the USM Anywhere Sensor.

   To learn how to configure your operating systems and supported third-party devices to forward syslog log data, see the following related topics:

• The Syslog Server Sensor App: Log collection (UDP, TCP, and TLS-encrypted TCP) from rsyslog
• Collecting Linux System Logs: Log collection from a Linux system
• Collecting Windows System Logs: Log collection from a Windows system
• Go to the specific BlueApp in USM Anywhere for instructions about syslog forwarding

Note: Because the log scan can take some time, you might not see all of the automatically discovered log sources immediately after deploying the first USM Anywhere Sensor.

2. When you have finished the log collection setup and integrated any needed plugins, verify that the data transfer is occurring.
3. Click Next when this step is complete.

LevelBlue Labs™ Open Threat Exchange® (OTX™) is an open information-sharing and analysis network providing users with the ability to collaborate, research, and receive alerts on emerging threats and indicators of compromise (IoCs) such as IP addresses, file hashes, and domains.

You must have an OTX account to receive alerts based on threats identified in OTX. This account is separate from your USM Anywhere account. Go to The World’s First Truly Open Threat Intelligence Community to create an OTX account.

To enable USM Anywhere to evaluate event data against the latest OTX intelligence

1. Log in to OTX and open the API page (https://otx.alienvault.com/api).

2. In the DirectConnect API Usage pane, click the icon to copy your unique OTX connection key.

   

3. Return to the Open Threat Exchange (OTX) page of the USM Anywhere Sensor Setup Wizard and paste the value in the OTX Key text box.

   

4. Click Validate OTX Subscription Key.

   With a successful validation of the key, the status at the top of the page changes to "Valid OTX key".

5. Click Next when this task is complete.

The Congratulations page summarizes the status of your configuration.

Click Start Using USM Anywhere, which takes you to the Overview dashboard.
