Integration Details

ThreatQuotient provides the following details for this integration:

Introduction

The Netscout Arbor Edge Defense (AED) connector ingests alerts from Netscout into ThreatQ.

Prerequisites

Review the following requirements before attempting to install the connector.  

Time Zone

The time zone steps are for ThreatQ v5 only.  You can skip these steps if you are on a ThreatQ v6 instance.  

You should ensure all ThreatQ devices are set to the correct time, time zone, and date (UTC is recommended), and using a clock source available to all.

To identify which time zone is closest to your present location, use the timedatectl command with the list-timezones command line option.

For example, enter the following command to list all available time zones in Europe:

timedatectl list-timezones | grep Europe 
Europe/Amsterdam 
Europe/Athens 
Europe/Belgrade 
Europe/Berlin

Enter the following command, as root, to change the time zone to UTC:

timedatectl set-timezone UTC

Integration Dependencies

The integration must be installed in a python 3.6 environment.

The following is a list of required dependencies for the integration.  These dependencies are downloaded and installed during the installation process.  If you are an Air Gapped Data Sync (AGDS) user, or run an instance that cannot connect to network services outside of your infrastructure, you will need to download and install these dependencies separately as the integration will not be able to download them during the install process.

Items listed in bold are pinned to a specific version.  In these cases, you should download the version specified to ensure proper function of the integration.

Installation

The following provides you with steps on installing a Python 3 Virtual Environment and installing the connector.

Installation Steps will differ based on whether you are running ThreatQ v6 or ThreatQ v5.

Upgrading Users - Review the Change Log for updates to configuration parameters before updating.  If there are changes to the configuration file (new/removed parameters), you must first delete the previous version's configuration file before proceeding with the install steps listed below.  The location of this file will differ between ThreatQ v6 and v5.  Failure to delete the previous configuration file will result in the connector failing.

  1. Download the connector integration file from the ThreatQ Marketplace.  
  2. Transfer the connector whl file to the /tmp/ directory on your instance.
  3. SSH into your instance.
  4. Move the connector whl file from its /tmp/ location to the following directory: /opt/tqvenv
  5. Navigate to the custom connector container:
    kubectl exec -n threatq -it deployments/custom-connectors -- /bin/bash

  6. Create your python 3 virtual environment:
    python3.6 -m venv /opt/tqvenv/<environment_name>

  7. Active the new environment:
    source /opt/tqvenv/<environment_name>/bin/activate

  8. Run the pip upgrade command:
    pip install --upgrade pip

  9. Install the required dependencies:
    pip install setuptools==59.6.0 threatqsdk threatqcc

  10. Install the connector:
    pip install /opt/tqvenv/tq_netscout_aed-<version>-py3-none-any.whl

  11. Perform an initial run of the connector:
    /opt/tqvenv/<environment_name>/bin/tq-conn-netscout-aed --cron="0 */2 * * *"

    The --cron argument above is used to generate a cron job for the connector.  After running the command above, the cronjob will be created under the /etc/cron.d/ directory.  This entry will initially be commented out upon creation - see the CRON chapter for more details.  

  12. Enter the following parameters when prompted:
    Parameter Description

Usage

Use the following command to execute the driver:

/opt/tqvenv/<environment_name>/bin/tq-conn-netscout-aed

/opt/tqvenv/<environment_name>/bin/tq-conn-netscout-aed -v3 -ll /var/log/tq_labs/ -c /etc/tq_labs

Command Line Arguments

This connector supports the following custom command line arguments:

Argument Description
-h, --help  Shows this help message and exits. 
-ll LOGLOCATION, --loglocation LOGLOCATION  (ThreatQ v5 Only) Sets the logging location for the connector. The location should exist and be writable by the current. A special value of 'stdout' means to log to the console (this happens by default). 
-c CONFIG, --config CONFIG (ThreatQ v5 Only) This is the location of the configuration file for the connector. This location must be readable and writable by the current user. If no config file path is given, the current directory will be used. This file is also where some information from each run of the connector may be put (last run time, private oauth, etc.)
-d, --disable-ssl  This argument will allow you to disable SSL verification when making requests to the AED appliance.
-i, --import  This argument will allow you to run the import-only portion of the application.  This will import events from AED into ThreatQ.
-e, --export  This argument will allow you to run the export-only portion of the application.  This will export threat intelligence from ThreatQ to AED.
-n, --name (connector name)  This argument allows you to install the connector with a custom name.  This argument is mainly used when you want to install multiple instances of the connector.  For instance, if you have multiple saved searches that you want exported.  You can simply setup anew instance of this connector with a new name, for a new saved search.
--cron ThreatQ v6 Only - creates a CRON entry for the connector based on a pre-loaded ThreatQ template.  See the CRON section for more details. 

Accessing Connector Logs

ThreatQ version 6 aggregates the logs for all custom connectors to its output container.  You can access the container's log using the following command:

kubectl logs -n threatq deployments/custom-connectors

The connector log directory was created in 10 of the installation process and is identified using the -ll argument flag when executing the driver.

Accessing Connector Configuration

The custom connector configuration file can be found in the following directory: /etc/tq_labs/.  

The custom connector configuration file was created in step 10 of the install process and identified using the -c argument flag when executing the driver. 

CRON

The addition of the --cron argument in the initial run of connector, performed during the install process, resulted in the creation of a cron job file for the connector in the following directory: /etc/cron.d/.  The contents of the file will resemble the following structure:

#{schedule} root /bin/bash -c "source /etc/env-vars.sh; {venv_path}/bin/{executable} --config=/etc/tq_labs > /proc/1/fd/1 2>/proc/1/fd/2" 

The {schedule} will be replaced with the cron settings you entered with the --cron flag and the {executable} will be replaced for with the connector's driver command.

You will also see a # at the beginning of the file.  This comments out the job.  This allows you to configure the custom connector in the ThreatQ UI first.  After you have configured the connector in ThreatQ, you can remove the # from the file content's in order to activate the cron job.

To summarize this process:

  1. Install the connector and perform an initial run using the --cron argument to create the cron job.
  2. Complete the connector's configuration settings in the ThreatQ UI.
  3. Access the connector's cron file in the /etc/cron.d/ directory and remove the # from the beginning of the file.  

Automatic CRON configuration has been removed from this script. To run this script on a recurring basis, use CRON or some other jobs scheduler. The argument in the CRON script must specify the config and log locations.

Add an entry to your Linux crontab to execute the connector at a recurring interval. Depending on how quickly you need updates, this can be run multiple times a day (no more than once an hour) or a few times a week.

In the example below, the command will execute the connector every two hours.

  1. Log into your ThreatQ host via a CLI terminal session.
  2. Enter the following command:
    crontab -e

    This will enable the editing of the crontab, using vi. Depending on how often you wish the cronjob to run, you will need to adjust the time to suit the environment.

  3. Enter the commands below:

    Every 2 Hours Example

    0 */2 * * * /opt/tqvenv/<environment_name>/bin/tq-conn-netscout-aed -c /etc/tq_labs/ -ll /var/log/tq_labs/ -v3  

  4. Save and exit CRON.
