OneLogin is a cloud-based identity and access management provider that provides a unified access management platform to enterprise-level businesses and organizations. In this guide, we integrate the OneLogin SSO to authenticate users into the Wazuh platform.

There are three stages in the single sign-on integration.

  1. OneLogin Configuration

  2. Wazuh indexer configuration

  3. Wazuh dashboard configuration

OneLogin Configuration

  1. Create an account in OneLogin. Request a free trial if you don't have a paid license.

  2. Add the OneLogin extension to your browser.

  3. Create a new user.

    1. Log in to OneLogin web console, and select Administration > Users > New User.

    2. Complete the mandatory fields, assign a value in the Department field and click on Save User. In our case, the department is wazuh-readonly. This field will be used later in the Wazuh indexer configuration as the backend role.

    3. Select the user, navigate to More Actions and click on Change Password to assign a password to the user.

  4. Create a new app using the SAML Custom Connector (Advanced) template and configure the SAML settings.

    1. Go to Applications tab > Applications and then click on Add app.

    2. Search for SAML Custom Connector (Advanced) application. In Display Name, assign a name. In our case, we assigned the name Wazuh. Navigate to the Configuration tab and fill in the information:

      • Audience (EntityID): wazuh-saml

      • Recipient: https://<WAZUH_DASHBOARD_URL>/_opendistro/_security/saml/acs

      • ACS (Consumer) URL Validator: https://<WAZUH_DASHBOARD_URL>/_opendistro/_security/saml/acs

      • ACS (Consumer) URL: https://<WAZUH_DASHBOARD_URL>/_opendistro/_security/saml/acs

      • Login URL: https://<WAZUH_DASHBOARD_URL>/app/wazuh

      • SAML initiator: Service Provider

      • SAML nameID format: Unspecified

      • SAML issuer type: Specific

      • SAML signature element: Response

      Replace the <WAZUH_DASHBOARD_URL> field with the corresponding URL of your Wazuh dashboard instance.

      The configuration must be similar to the highlighted blue rectangles:

    3. Go to the Parameters tab and click on + to add a new parameter to the app:

    4. Edit the parameter details. In our case, we named the new parameter as Roles, then we selected the value Department and marked the Include in SAML assertion checkbox. The rest of the app configuration is left as default.

    5. Click on Save to apply the configuration.

  5. Add the created user to the new app.

    1. Go to Users and select the created user. Go to Applications and click on +, select the Allow the user to sign in checkbox, and click on Save.

  6. Get the metadata_onelogin.xml file and X.509 certificate from the application.

    1. Go to Applications > Applications then select the Wazuh app. Click on More Actions and then select SAML Metadata.

    2. Save the file as XML. This will be the idp.metadata_file in the Wazuh indexer security configuration.

    3. The Issuer URL will be the idp.entity_id in the Wazuh indexer security configuration.

    4. The Audience (EntityID) will be the sp.entity_id in the Wazuh indexer security configuration.

    5. The roles_key is the name of the parameter added in the Wazuh app. In our example, this is Roles.

    6. Finally, to obtain the exchange_key, go to the SSO tab of the Wazuh app and select View Details in X.509 Certificate. Copy the blob of the certificate excluding the -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----- lines:

Wazuh indexer configuration

Edit the Wazuh indexer security configuration files. We recommend that you back up these files before you carry out the configuration.

  1. Place the metadata_onelogin.xml file within the /etc/wazuh-indexer/opensearch-security/ directory. Set the file ownership to wazuh-indexer using the following command:

    # chown wazuh-indexer:wazuh-indexer /etc/wazuh-indexer/opensearch-security/metadata_onelogin.xml
  2. Edit the /etc/wazuh-indexer/opensearch-security/config.yml file and change the following values:

    • Set the order in basic_internal_auth_domain to 0 and the challenge flag to false.

    • Include a saml_auth_domain configuration under the authc section similar to the following:

            description: "Authenticate via HTTP Basic against internal users database"
            http_enabled: true
            transport_enabled: true
            order: 0
              type: "basic"
              challenge: false
              type: "intern"
            http_enabled: true
            transport_enabled: true
            order: 1
              type: saml
              challenge: true
                  metadata_file: '/etc/wazuh-indexer/opensearch-security/metadata_onelogin.xml'
                  entity_id: ''
                  entity_id: wazuh-saml
                kibana_url: https://<WAZUH_DASHBOARD_URL>
                roles_key: Roles
                exchange_key: 'MIIBkjCB/AIBADBTMQswCQ......'
              type: noop

    Ensure to change the following parameters to their corresponding value:

    • idp.metadata_file

    • idp.entity_id

    • sp.entity_id

    • kibana_url

    • roles_key

    • exchange_key

  3. Run the securityadmin script to load the configuration changes made in the config.yml file.

    # export JAVA_HOME=/usr/share/wazuh-indexer/jdk/ && bash /usr/share/wazuh-indexer/plugins/opensearch-security/tools/ -f /etc/wazuh-indexer/opensearch-security/config.yml -icl -key /etc/wazuh-indexer/certs/admin-key.pem -cert /etc/wazuh-indexer/certs/admin.pem -cacert /etc/wazuh-indexer/certs/root-ca.pem -h localhost -nhnv

    The -h flag specifies the hostname or the IP address of the Wazuh indexer node. Note that this command uses localhost, set your Wazuh indexer address if necessary.

    The command output must be similar to the following:

    Security Admin v7
    Will connect to localhost:9200 ... done
    Connected as "CN=admin,OU=Wazuh,O=Wazuh,L=California,C=US"
    OpenSearch Version: 2.8.0
    Contacting opensearch cluster 'opensearch' and wait for YELLOW clusterstate ...
    Clustername: wazuh-cluster
    Clusterstate: GREEN
    Number of nodes: 1
    Number of data nodes: 1
    .opendistro_security index already exists, so we do not need to create one.
    Populate config from /etc/wazuh-indexer/opensearch-security
    Will update '/config' with /etc/wazuh-indexer/opensearch-security/config.yml
       SUCC: Configuration for 'config' created or updated
    SUCC: Expected 1 config types for node {"updated_config_types":["config"],"updated_config_size":1,"message":null} is 1 (["config"]) due to: null
    Done with success

Wazuh dashboard configuration

  1. Create a new role mapping for the backend role. Follow these steps to create a new role mapping, and grant read-only permissions to the backend role.

    1. Log into the Wazuh dashboard as administrator.

    2. Click the upper-left menu icon to open the options, select Security, and then Roles to open the roles page.

    3. Click Create role, complete the empty fields with the following parameters, and then click Create to complete the task.

      • Name: Assign a name to the role.

      • Cluster permissions: cluster_composite_ops_ro

      • Index: *

      • Index permissions: read

      • Tenant permissions: Select global_tenant and the Read only option.

    4. Select the newly created role.

    5. Select the Mapped users tab and click Manage mapping.

    6. Under Backend roles, add the value of the Department field in OneLogin configuration and click Map to confirm the action. In our case, the backend role is wazuh-readonly.

  2. Check the value of run_as in the /usr/share/wazuh-dashboard/data/wazuh/config/wazuh.yml configuration file. If run_as is set to false, proceed to the next step.

      - default:
          url: https://localhost
          port: 55000
          username: wazuh-wui
          password: "<wazuh-wui-password>"
          run_as: false

    If run_as is set to true, you need to add a role mapping on the Wazuh dashboard. To map the backend role to Wazuh, follow these steps:

    1. Click the upper-left menu icon to open the available options.

    2. Click Wazuh to open the Wazuh dashboard menu, select Security, and then Roles mapping to open the page.

      Create Wazuh role mapping
    4. Click Save role mapping to save and map the backend role with Wazuh as read-only.

  3. Edit the Wazuh dashboard configuration file. Add these configurations to /etc/wazuh-dashboard/opensearch_dashboards.yml. We recommend that you back up these files before you carry out the configuration.

    opensearch_security.auth.type: "saml"
    server.xsrf.allowlist: ["/_opendistro/_security/saml/acs", "/_opendistro/_security/saml/logout", "/_opendistro/_security/saml/acs/idpinitiated"]
    opensearch_security.session.keepalive: false
  4. Restart the Wazuh dashboard service.

    # systemctl restart wazuh-dashboard
  5. Test the configuration. Go to your Wazuh dashboard URL and log in with your OneLogin account.
