Configure your firewall rules

If your ExtraHop system is deployed in an environment with a firewall, you must open access to ExtraHop Cloud Services. For Reveal(x) 360 systems that are connected to self-managed sensors, you must also open access to the ExtraHop Cloud Recordstore.

Open access to Cloud Services

For access to ExtraHop Cloud Services, your sensors must be able to resolve DNS queries for *.extrahop.com and access TCP 443 (HTTPS) from the IP address that corresponds to your sensor license:

  • 35.161.154.247 (Portland, U.S.A.)
  • 54.66.242.25 (Sydney, Australia)
  • 52.59.110.168 (Frankfurt, Germany)

Open access to Cloud Recordstore

For access to the ExtraHop Cloud Recordstore, your sensors must be able to access outbound TCP 443 (HTTPS) to these fully-qualified domain names:

  • bigquery.googleapis.com
  • bigquerystorage.googleapis.com
  • oauth2.googleapis.com
  • www.googleapis.com
  • www.mtls.googleapis.com
  • iamcredentials.googleapis.com

You can also review the public guidance from Google about computing possible IP address ranges for googleapis.com.

In addition to configuring access to these domains, you must also configure the global proxy server settings.

Enable detection tracking

Detection tracking enables you to assign a detection to a user, set the status, and add notes. You can track detections directly in the ExtraHop system, with a third-party external ticketing system, or with both methods.

Note:You must enable ticket tracking on all connected sensors.

Before you begin

  • You must have access to an ExtraHop system with a user account that has Administration privileges.
  • After you enable external ticket tracking, you must configure third-party ticket tracking by writing a trigger to create and update tickets on your ticketing system, then enable ticket updates on your ExtraHop system through the REST API.
  • If you disable external ticket tracking, previously stored status and assignee ticket information is converted to ExtraHop detection tracking. If detection tracking from within the ExtraHop system is enabled, you will be able to view tickets that already existed when you disabled external ticket tracking, but changes to that external ticket will not appear in the ExtraHop system.
  1. From the Overview page, click System Settings and then click All Administration.
  2. From the Console Settings section, click Detection Tracking.
  3. Select one or both of the following methods for tracking detections:
    • Select Enable ExtraHop users to track detections from within the ExtraHop system.
    • Select Enable external integrations, such as SOAR or ticket tracking systems, to track detections through the ExtraHop Rest API.
  4. (Optional): After you select the option to enable external integrations, specify the URL template for your ticketing system and add the $ticket_id variable at the appropriate location. For example, type a complete URL such as https://jira.example.com/browse/$ticket_id. The $ticket_id variable is replaced with the ticket ID associated with the detection.
    After the URL template is configured, you can click the ticket ID in a detection to open the ticket in a new browser tab.

Next steps

If you enabled external ticket tracking integrations, you must continue on to the following task:

Configure third-party ticket tracking for detections

Ticket tracking enables you to connect tickets, alarms, or cases in your work-tracking system to ExtraHop detections. Any third-party ticketing system that can accept Open Data Stream (ODS) requests, such as Jira or Salesforce, can be linked to ExtraHop detections.

Before you begin

Write a trigger to create and update tickets about detections on your ticketing system

This example shows you how to create a trigger that performs the following actions:

  • Create a new ticket in the ticketing system every time a new detection appears on the ExtraHop system.
  • Assign new tickets to a user named escalations_team in the ticketing system.
  • Run every time a detection is updated on the ExtraHop system.
  • Send detection updates over an HTTP Open Data Stream (ODS) to the ticketing system.

The complete example script is available at the end of this topic.

  1. Log in to the ExtraHop system through https://<extrahop-hostname-or-IP-address>.
  2. Click the System Settings icon and then click Triggers.
  3. Click New.
  4. Specify a name and optional description for the trigger.
  5. From the Events list, select DETECTION_UPDATE.
    The DETECTION_UPDATE event runs every time that a detection is created or updated in the ExtraHop system.
  6. In the right pane, specify Detection class parameters in a JavaScript object. These parameters determine the information that is sent to your ticketing system.
    The following example code adds the detection ID, description, title, categories, MITRE techniques and tactics, and risk score to a JavaScript object called payload:
    const summary = "ExtraHop Detection: " + Detection.id + ": " + Detection.title;
const description = "ExtraHop has detected the following event on your network: " + Detection.description 
const payload = {
    "fields": {
        "summary": summary,
        "assignee": {
            "name": "escalations_team"
        },
        "reporter": {
            "name": "ExtraHop"
        },
        "priority": {
            "id": Detection.riskScore
        },
        "labels": Detection.categories,
        "mitreCategories": Detection.mitreCategories,
        "description": description
    }
};
  7. Next, define the HTTP request parameters in a JavaScript object below the previous JavaScript object.
    The following example code defines an HTTP request for the payload described in the previous example: defines a request with a JSON payload:
    const req = {
    'path': '/rest/api/issue',
    'headers': {
        'Content-Type': 'application/json'
    },
    'payload': JSON.stringify(payload)
};

    For more information about ODS request objects, see Open data stream classes.

  8. Finally, specify the HTTP POST request that sends the information to the ODS target. The following example code sends the HTTP request described in the previous example to an ODS target named ticket-server: 
    Remote.HTTP('ticket-server').post(req);
The complete trigger code should look similar to the following example:
const summary = "ExtraHop Detection: " + Detection.id + ": " + Detection.title;
const description = "ExtraHop has detected the following event on your network: " + Detection.description 
const payload = {
    "fields": {
        "summary": summary,
        "assignee": {
            "name": "escalations_team"
        },
        "reporter": {
            "name": "ExtraHop"
        },
        "priority": {
            "id": Detection.riskScore
        },
        "labels": Detection.categories,
        "mitreCategories": Detection.mitreCategories,
        "description": description
    }
};

const req = {
    'path': '/rest/api/issue',
    'headers': {
        'Content-Type': 'application/json'
    },
    'payload': JSON.stringify(payload)
};

Remote.HTTP('ticket-server').post(req);

Send ticket information to detections through the REST API

After you have configured a trigger to create tickets for detections in your ticket tracking system, you can update ticket information on your ExtraHop system through the REST API.

Ticket information appears in detections on the Detections page in the ExtraHop system. For more information, see the Detections topic.

The following example Python script takes ticket information from a Python array and updates the associated detections on the ExtraHop system.

#!/usr/bin/python3

import json
import requests
import csv

API_KEY = '123456789abcdefghijklmnop'
HOST = 'https://extrahop.example.com/'

# Method that updates detections on an ExtraHop system
def updateDetection(detection):
    url = HOST + 'api/v1/detections/' + detection['detection_id']
    del detection['detection_id']
    data = json.dumps(detection)
    headers = {'Content-Type': 'application/json',
               'Accept': 'application/json',
               'Authorization': 'ExtraHop apikey=%s' % API_KEY}
    r = requests.patch(url, data=data, headers=headers)
    print(r.status_code)
    print(r.text)

# Array of detection information
detections = [
                 {
                     "detection_id": "1",
                     "ticket_id": "TK-16982",
                     "status": "new",
                     "assignee": "sally",
                     "resolution": None,
                 },
                 {
                     "detection_id": "2",
                     "ticket_id": "TK-2078",
                     "status": None,
                     "assignee": "jim",
                     "resolution": None,
                 },
                 {
                     "detection_id": "3",
                     "ticket_id": "TK-3452",
                     "status": None,
                     "assignee": "alex",
                     "resolution": None,
                 }
             ]

for detection in detections:
    updateDetection(detection)
Note:If the script returns an error message that the SSL certificate verification failed, make sure that a trusted certificate has been added to your sensor or console. Alternatively, you can add the verify=False option to bypass certificate verification. However, this method is not secure and not recommended. The following code sends an HTTP GET request without certificate verification:
requests.get(url, headers=headers, verify=False)
After ticket tracking is configured, ticket details are displayed in the left pane of the detection details, similar to the following figure:
Status
The status of the ticket associated with the detection. Ticket tracking supports the following statuses:
  • New
  • In Progress
  • Closed
  • Closed with Action Taken
  • Closed with No Action Taken
Ticket ID
The ID of the ticket in your work-tracking system that is associated with the detection. If you have configured a template URL, you can click the ticket ID to open the ticket in your work-tracking system.
Assignee
The username assigned to the ticket associated with the detection. Usernames in gray indicate a non-ExtraHop account.

Connect sensors

Add sensors to Reveal(x) 360 to monitor your network traffic.

ExtraHop-managed Reveal(x) sensors for AWS can be selected and deployed from within the Reveal(x) 360 console.

Self-managed sensors and packetstores can also be connected from within the Reveal(x) 360 console. Note that if you have an existing console, you must disconnect the console before connecting your self-managed sensors to Reveal(x) 360.

Integrations

The Integrations page displays a catalog of products and solutions from third-party vendors that work with the ExtraHop system. Integrations can provide insight into how your devices are communicating in your environment or improve your ability to investigate threats and issues.

Requirements and configurations vary by integration. Some integrations require that you install and configure an app or add-on, and most integrations require that you create credentials to access the ExtraHop REST API.

Click a tile to view more information about the integration.

Multi-factor authentication

Multi-factor Authentication (MFA) is a security enhancement that requires you to provide two forms of credentials when you log in to your account. In addition to your ExtraHop credentials, you must supply credentials from a 3rd-party authenticator app.

Select and download an authentication application to your device and generate secure, six-digit codes when you log in to your Reveal(x) 360 system.

There are many authenticator apps to select from. The following steps are a general guideline, but you should also review the help documentation for the app you select.

  1. Choose a device, such as a computer or mobile device (phone or tablet), on which you can install apps.
  2. Download and install an authentication app on the device. Here are some popular options:
    • Android and iOS: Google Authenticator, Authy
    • Windows and macOS: 1Password, OTP Manager
    • Chrome extensions: Authenticator
  3. Open a new browser and sign in to your ExtraHop Reveal(x) 360 system.
  4. Follow the instructions to scan or enter the code that appears on the ExtraHop Multi-Factor Authentication setup screen, and then enter the credentials provided by your authenticator app.

Upgrade connected sensors in Reveal(x) 360

Administrators can upgrade sensors that are connected to Reveal(x) 360.

Before you begin

  • Your user account must have privileges on Reveal(x) 360 for System and Access Administration or System Administration.
Here are some considerations about upgrading sensors:
  • Sensors must be connected to ExtraHop Cloud Services
  • Notifications appear when a new firmware version is available
  • You can upgrade multiple sensors at the same time
  1. From the Overview page, click System Settings and then click Sensors.
    Sensors that are eligible for upgrade display an up arrow in the Sensor Version field.
  2. Select the checkbox next to each sensor that you want to upgrade.
  3. In the Sensor Details pane, select the firmware version from the Available Firmware drop-down list.

    The drop-down list only displays versions that are compatible with the selected sensors.

    Only the selected sensors that have a firmware upgrade available appear in the Sensor Details pane.

  4. Click Install Firmware.

    When the upgrade completes, the Sensor Version field is updated with the new firmware version.

Active device count and limit

The Active Device Count and Limit chart on the main Administration page enables you to monitor whether your active device count has exceeded the licensed limit. For example, an ExtraHop system with a 20,000-50,000 devices band is allowed up to 50,000 devices.

Click System Settings and then click All Administration to view the chart.

The Active Device Count and Limit chart displays the following metrics:

  • The dashed red line represents the licensed device limit.
  • The solid black line represents the 95th percentile of active devices observed each day for the last 30 days.
  • The blue bars represent the maximum number of active devices observed each day for the last 30 days.

This page also displays the following metrics:

  • The licensed device limit for the previous day and for the last 30 days.
  • The number of active devices observed the previous day.
  • The 95th percentile of active devices observed over the last 30 days.
  • The utilization percentage of the licensed device limit for the previous day and for the last 30 days. Utilization is the active device count divided by the licensed limit.

You can create a system notification rule to warn you if utilization is near (exceeds 80%) or over (exceeds 100%) your licensed device limit. Limit percentages are customizable when you create a rule. If you find that you are consistently approaching or over your licensed limit, we recommend that you work with your sales team to move to the next available capacity band.

Record ingest and capacity

The Record Ingest and Capacity chart on the main Administration page enables you to monitor the record ingest and capacity levels and confirm that the capacity limit is optimal for your environment.

The dashed red line on the bar chart represents your record ingest capacity, and the blue bars represent the amount of ingest each day during the selected interval. You can select an interval of 30, 60, 90, 120, or 180 days depending on the amount of licensed record lookback, which is displayed to the right of the bar chart.

Ingest and utilization charts are displayed to help you track record ingest. You can create a system notification rule to warn you if record ingest is near (exceeds 80%) or over (exceeds 100%) your daily record ingest capacity.

If you find that you are consistently over your allotted capacity, contact your ExtraHop sales representative.
