    See the NetWitness Platform 11.6 Licensing Management Guide for more information. Go to the Master Table of Contents to find all RSA NetWitness Platform 11.x documents.

    Note: NetWitness Platform supports the User and Entity Behavior Analytics License (UEBA). This license is used based on the number of users. The Out-of-the-Box Trial License is a 90-day trial license. In case of UEBA licenses, the 90-day trial period begins from the time the UEBA service deployed on the NetWitness Platform product.

Configure NetWitness UEBA

To start running UEBA:

  1. Define the following parameters: data schemas, data source (NetWitness Broker or Concentrator) and start date.

    1. Define UEBA schemas:
      Choose schemas from the following list:

      AUTHENTICATION, FILE, ACTIVE_DIRECTORY, PROCESS, REGISTRY and TLS.

      Note: The TLS packet requires adding the hunting package and enabling the JA3 feature. For more information regarding events that each schema contains, see the NetWitness UEBA Configuration Guide.

    2. Define the data source:
      If your deployment has multiple Concentrators, we recommend that you assign a Broker at the top of your deployment hierarchy for the NetWitness UEBA data source.

    3. Define the UEBA start-date:

      Note: The selected start date must contain events from all configured schemas.

      RSA recommends that the UEBA start date is set to 28 days earlier than the current date. For UEBA systems that intend to process TLS data, you must make sure that the start date is set to no later than 14 days earlier than the current date.

  2. . Create a user account for the data source (Broker or Concentrator) to authenticate to the data.
    1. Log into NetWitness Platform.
    2. Go to netwitness_adminicon_25x22.png (Admin) > Services.
    3. Locate the data source service (Broker or Concentrator).
      Select that service, and select netwitness_actiondd.png (Actions) > View > Security.

    4. Create a new user and assign the “Analysts” role to that user.

      The following example shows a user account created for a Broker.

      netwitness_ueba_login_datasource.png

  3. SSH to the NetWitness UEBA server host.
  4. (For Virtual Machines Only) Set the appropriate parallelism value:
    If the UEBA system runs on VM, update the airflow parallelism value to be 64 by running the following command:
    sed -i "s|parallelism = 256|parallelism = 64|g" /var/netwitness/presidio/airflow/airflow.cfg

  5. Submit the following commands with the above parameters that you already defined.
    /opt/rsa/saTools/bin/ueba-server-config -u <user> -p <password> -h <host> -o <type> -t <startTime> -s <schemas> -v -e <argument>
    Where:
Argument Variable Description
-u <user> User name of the credentials for the Broker or Concentrator instance that you are using as a data source.
-p <password>

Password of the credentials for the Broker or Concentrator instance that you are using as a data source. The following special characters are supported in a password.

!"#$%&()*+,-:;<=>?@[\]^_`\{|}

If you want to include a special character or special characters, you must delimit the password with an apostrophe sign, for example:
sh /opt/rsa/saTools/bin/ueba-server-config -u brokeruser -p '!"UHfz?@ExMn#$' -h 10.64.153.104 -t 2018-08-01T00:00:00Z -s 'AUTHENTICATION FILE ACTIVE_DIRECTORY TLS PROCESS REGISTRY' -o broker -v

-h <host> IP address of the Broker or Concentrator used as the data source. Currently, only one data source is supported.
-o <type> Data source host type (broker or concentrator).
-t <startTime>

Historical start time as of which you start collecting data from the data source in YYYY-MM-DDTHH-MM-SSZ format (for example, 2018-08-15T00:00:00Z).

Note: The script interprets the time you enter as UTC (Coordinated Universal Time) and it does not adjust the time to your local time zone.

-s <schemas>

Array of data schemas. If you want to specify multiple schemas, use a space to separate each schema (for example, AUTHENTICATION FILE ACTIVE_DIRECTORY PROCESS REGISTRY TLS).

-v verbose mode.
-e <argument>

Boolean Argument. This enables the UEBA indicator forwarder to Respond.

Note: If your NetWitness deployment includes an active Respond server, you can transfer NetWitness UEBA indicators to the Respond server and create incidents by enabling the indicator forwarder, from this data. For more information on how to enable the NetWitness UEBA incidents aggregation, see Installation Tasks.

  1. Set the appropriate "Boot Jar Pools" slots:

    • Physical Appliance: Update the spring_boot_jar_pool" slots to be 18.

    • Virtual Appliance: If the UEBA system is running on VM, update the spring_boot_jar_pool and the retention_spring_boot_jar_pool slots values to 5.
      To update the “Spring Boot Jar Pools” slots, Go to the Airflow main page, tap the “Admin” tab at the top bar and tap “Pools”.

    1. To access the Airflow UI, go to https://<UEBA_host>/admin and enter the credentials.

    • User: admin

    • Password: The environment deploy admin password.

    1. Click on the pencil mark of the polls to update the slot values.
