Step 3: Add Imperva as a Security Device in Workbench

  1. Log in to Workbench.
  2. In the side menu, navigate to Organization Settings > Security Devices.
  3. Select Add Security Device.
  4. In the search box, type “Imperva” and then select the Imperva integration.
  5. A configuration pane displays. Complete the fields as follows:
    1. Name - enter a name that might help you more easily identify this integration, such as “CompanyName Imperva WAF”; this name will display in Workbench under the Name column, and is a text string that you can filter on.
    2. Location - enter the location of your integration, for example, “cloud.” This is also a text string that you can filter on, so we recommend being consistent with location naming across your Expel integrations.
    3. Connection Settings - provide the appropriate information:
      • Expel Imperva API ID - enter the API ID you generated in Step 2.5.
      • API key for Expel Imperva email - enter the API key you generated in Step 2.5.
  6. Select Save.
  7. Your device should be created successfully within a few seconds.

    You can see if the device is healthy on the Security Devices page in Workbench. It may take a few minutes to see the device listed as healthy.

Step 4: Edit the Device to Add Console Access

Expel needs console access to your device to allow our SOC analysts to dig deeper during incident investigations. Additionally, our engineering teams use this access to investigate potential health issues, including proper alert ingestion.

Note
Expel secures all login information our SOC analysts need about your devices in an MFA password product. Access to this login information is protected using our internal MFA processes. Learn more about the IP addresses all Expel traffic comes from.

  1. Open Workbench. Go to Organization Settings > Security Devices. Next to the device you just connected, click the down arrow and click Edit.

  2. In the Console Login area, type these details:

    • Console URL - type the console URL from the Server address in the Connection Settings area above. At the end of the URL, type /login.

    • Username - type the user name you created above.

    • Password - type the password you created above.

    • Two-factor secret key (32-character code) - depending on how your organization enforces logins, this field may not apply to you. In these cases, you can leave it blank. This field is optional and if you have questions or concerns, contact Support.

  3. Click Save.
