By following these steps, you create a user account for Expel which keeps Expel activity separate from other activity on the Wazuh console.

Note

This guide is for cloud installations of Wazuh. For on-premises installations, see the Wazuh on-prem article.

Step 1: Get the Elastic API

  1. Ask Wazuh support (cloud@wazuh.com) to expose the Elastic API and allow list these 6 IPs:

  2. Write down the exposed Elastic API. Your API URL should be similar to https://<cloud_instance>.cloud.wazuh.com/api/elastic/. Notify your engagement manager if your URL doesn't end with the suffix /api/elastic.

Step 2: Create an account in Elastic

This step configures a user with a read-only role for Expel to access this API.

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. To learn more about the IP addresses all Expel traffic comes from, go here.

  1. Go to Open Distro for Elasticsearch > Security > Roles > Create > Role.

  2. Create a role with these options:

    • Cluster Permissions: cluster_all.

    • Index Permissions: Add the index - * , with index permissions - search, get, read.

    • Tenant permissions: global_tenant with Read only.

  3. Go to the Mapped Users tab and select Create Internal User.

  4. Type a username and password for the new user and write them down.

  5. Go back to the Roles screen and click Map users.

  6. Select the newly created user and click Save.

  7. Go to Wazuh > Security > Roles mapping.

  8. Create a new Role mapping with these options:

    • Roles: readonly.

    • Internal users: select the newly created user from the list.

Step 3: Setup the archives index

This step sets up the Wazuh-archives index.

  1. Go to Wazuh > Management > Configuration > Edit Configuration.

  2. Change the logall_json setting to yes.

    <ossec_config> <ossec_config> <global> <jsonout_output>yes</jsonout_output> <alerts_log>yes</alerts_log> <logall>no</logall> <logall_json>yes</logall_json> </global>

  3. After you configure the archive, the archive file goes to cold storage. For investigative purposes, we want to query this index in real-time. The next step is to reach out to your Wazuh support team to change this index to hot storage. This is a change to the filebeat.yml file which must be done by the Wazuh cloud support team.

Step 4. Configure the technology in Workbench

  1. In a new browser tab, log into https://workbench.expel.io/settings/security-devices?setupIntegration=wazuh. You may be asked to log into Workbench.

  2. Fill out the form like this:

    mceclip9.png
    • Where is your device? Cloud.

    • Name: any name for the integration.

    • Location: Cloud.

    • Username: Username for the newly created user.

    • Password: Password for the newly created user.

    • Server address: type the Wazuh cloud server address.

      Note

      Don't type the Elastic API address.

    • Is this a Wazuh cloud Instance?: select Yes.

  3. You can set up console access now or use the instructions below to set it up later.
