PingOne

PingOne for Enterprise is an identity-as-a-service (IDaaS) and single sign-on (SSO) platform. It allows enterprises to give their users federated access to applications. In this guide, we integrate the PingOne IdP to authenticate users into the Wazuh platform.

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

PingOne Configuration
Wazuh indexer configuration
Wazuh dashboard configuration

PingOne Configuration

Create an account in Ping Identity. Request a free trial if you don't have a paid license.
Go to PingOne and sign in with your Ping Identity account.
Create an application in Connections.
1. Navigate to Connections > Applications > Add Application and give it a name. In our case, the name is wazuh-sso.
2. Proceed to the Choose Application Type section, and select SAML Application > Configure.
3. Select Manually Enter on the Provide App Metadata section and add the following configuration, replacing <WAZUH_DASHBOARD_URL> with the corresponding value:
  - ACS URLs: https://<WAZUH_DASHBOARD_URL>/_opendistro/_security/saml/acs
  - Entity ID: wazuh-saml
4. On the Configuration tab, click on the edit icon and add the following information:
  - SLO ENDPOINT: https://<WAZUH_DASHBOARD_URL>/
  - SLO BINDING: HTTP Redirect
  - ASSERTION VALIDITY DURATION: 3600 (for one hour token validity)
  - VERIFICATION CERTIFICATE (OPTIONAL): Load a PUBLIC CERTIFICATE that corresponds to the PRIVATE KEY that is going to be used on the sp.signature_private_key_filepath of the config.yml configuration file on the Wazuh indexer instance. This is necessary as all the logout requests must be signed.
5. Click on the Attribute Mappings tab, select the edit icon, click on Add and insert the following configuration:
  
  Roles = Group Names
  
  The Roles attribute will be used later as the sp.entity_id in the Wazuh indexer configuration file.
6. Click on the Required checkbox, and click on Save.
Create a group and assign users.
1. Navigate to Identities > Groups, and click on the + sign. Select the name of the Group, in this case, Role.
2. To assign users, open the created Group, go to the Users tab and select Add Individually. Add all the members that must log in to the Wazuh dashboard, and click on Save when done.
Activate the application and note the necessary parameters.
1. Navigate to Connections, select Applications, and enable the application.
2. Take note of the following parameters from the configuration page of the application. This information will be used in the next step.
  - ISSUER ID: It'll be in the form https://auth.pingone.com/...
  - IDP METADATA URL: It’ll be in the form https://auth.pingone.com/...
  - exchange_key: If you open the IDP METADATA URL you'll find the X509 Certificate section, this will be used as the exchange_key.

Wazuh indexer configuration

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

Place the private key 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/securityconfig/PRIVATE_KEY
```

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:

    authc:
...
      basic_internal_auth_domain:
        description: "Authenticate via HTTP Basic against internal users database"
        http_enabled: true
        transport_enabled: true
        order: 0
        http_authenticator:
          type: "basic"
          challenge: false
        authentication_backend:
          type: "intern"
      saml_auth_domain:
        http_enabled: true
        transport_enabled: false
        order: 1
        http_authenticator:
          type: saml
          challenge: true
          config:
            idp:
              metadata_url: IDP METADATA URL
              entity_id: ISSUER ID
            sp:
              entity_id: wazuh-saml
              signature_private_key_filepath: /etc/wazuh-indexer/opensearch-security/PRIVATE_KEY
              forceAuthn: true
            kibana_url: https://<WAZUH_DASHBOARD_URL>
            roles_key: Roles
            exchange_key: 'MIIJ6DLSAAbAmAJHSgIWYia.........'
        authentication_backend:
          type: noop

Ensure to change the following parameters to their corresponding value:

idp.metadata_file
idp.entity_id
sp.entity_id
sp.signature_private_key_filepath
kibana_url
roles_key
exchange_key

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/securityadmin.sh -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

OpenSearch Version: 2.8.0

   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

Edit the /etc/wazuh-indexer/opensearch-security/roles_mapping.yml file and change the following values:

Map the Group (Role) that is in PingOne to the all_access role in Wazuh indexer:
```
all_access:
  reserved: false
  hidden: false
  backend_roles:
  - "admin"
  - "Role"
  description: "Maps admin to all_access"
```

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

# export JAVA_HOME=/usr/share/wazuh-indexer/jdk/ && bash /usr/share/wazuh-indexer/plugins/opensearch-security/tools/securityadmin.sh -f /etc/wazuh-indexer/opensearch-security/roles_mapping.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

Wazuh dashboard configuration

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.
```
hosts:
  - 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 Wazuh to open the Wazuh dashboard menu, select Security, and then Roles mapping to open the page.
2. Click Create Role mapping and complete the empty fields with the following parameters:
  - Role mapping name: Assign a name to the role mapping.
  - Roles: Select administrator.
  - Custom rules: Click Add new rule to expand this field.
  - User field: backend_roles
  - Search operation: FIND
  - Value: Assign the name you gave to your group in PingOne configuration, in our case, this is Role.
3. Click Save role mapping to save and map the backend role with Wazuh as administrator.

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

Restart the Wazuh dashboard service.

# systemctl restart wazuh-dashboard

# service wazuh-dashboard restart

Test the configuration. Go to your Wazuh dashboard URL and log in with your Ping One account.
