## authentik configuration
|
|
|
|
To support the integration of Wazuh with authentik, you need to create a group, a property mapping, and an application/provider pair in authentik.
|
|
|
|
### Create a user group in authentik
|
|
|
|
1. Log in to authentik as an administrator and open the authentik Admin interface.
|
|
2. Navigate to **Directory** > **Groups** and click **Create**.
|
|
3. Set a name for the group (e.g. `wazuh-administrators`) and click **Create**.
|
|
4. Click the name of the newly created group and navigate to the **Users** tab.
|
|
5. Click **Add existing user**, select the user that needs Wazuh admin access and click **Add**.
|
|
|
|
### Create a property mapping in authentik
|
|
|
|
1. Log in to authentik as an administrator and open the authentik Admin interface.
|
|
2. Navigate to **Customization** > **Property Mappings** and click **Create**. Create a **SAML Provider Property Mapping** with the following settings:
|
|
|
|
- **Name**: Choose a descriptive name
|
|
- **SAML Attribute Name**: `Roles`
|
|
- **Friendly Name**: Leave blank
|
|
- **Expression**: `wazuh-administrators` is used a placeholder for the group name.
|
|
|
|
```python
|
|
if ak_is_group_member(request.user, name="wazuh-administrators"):
|
|
yield "wazuh-admin"
|
|
```
|
|
|
|
3. Click **Finish**.
|
|
|
|
### Create an application and provider in authentik
|
|
|
|
1. Log in to authentik as an administrator and open the authentik Admin interface.
|
|
2. Navigate to **Applications** > **Applications** and click **Create with Provider** to create an application and provider pair. (Alternatively you can first create a provider separately, then create the application and connect it with the provider.)
|
|
|
|
- **Application**: provide a descriptive name (e.g., `Wazuh`), an optional group for the type of application, the policy engine mode, and optional UI settings.
|
|
- **Choose a Provider type**: Select **SAML Provider** as the provider type.
|
|
- **Configure the Provider**: provide a name (or accept the auto-provided name), the authorization flow to use for this provider, and the following required configurations.
|
|
- **ACS URL**: `https://wazuh-dashboard.company/\_opendistro/\_security/saml/acs`
|
|
- **Issuer**: `wazuh-saml`
|
|
- **Service Provider Binding**: `Post`
|
|
- Under **Advanced protocol settings**:
|
|
- **Property Mappings**: add the **Property Mapping** you created in the previous section.
|
|
- **NameID Property Mapping**: select a property mapping that will be used for Wazuh usernames (e.g. `authentik default SAML Mapping: Name` or `authentik default SAML Mapping: Email`)
|
|
- **Configure Bindings** _(optional)_: you can create a [binding](/docs/add-secure-apps/flows-stages/bindings/) (policy, group, or user) to manage the listing and access to applications on a user's **My applications** page.
|
|
|
|
3. Click **Submit** to save the new application and provider.
|
|
|
|
### Download metadata file
|
|
|
|
1. Log in to authentik as an administrator and open the authentik Admin interface.
|
|
2. Navigate to **Applications** > **Providers** and click on the name of the provider that you created in the previous section (e.g. `Provider for wazuh`).
|
|
3. Under **Related objects** > **Metadata**, click on **Download**. This downloaded file is your `SAML Metadata` file and it will be required in the next section.
|
|
|
|
## Wazuh configuration
|
|
|
|
To support the integration of authentik with Wazuh, you will need to configure SAML authentication on the Wazuh Indexer server and create role mappings on the Wazuh Dashboard server.
|
|
|
|
### Wazuh Indexer SAML configuration
|
|
|
|
:::note
|
|
The file `wazuh_authentik_meta.xml` serves as a placeholder for your SAML Metadata file. Ensure that the filename used in this context matches the name of your SAML Metadata file.
|
|
:::
|
|
|
|
1. For the next step, you will need an exchange key. To generate this key, use the following command:
|
|
|
|
```bash
|
|
openssl rand -hex 32
|
|
```
|
|
|
|
2. Copy the downloaded metadata file to the `/etc/wazuh-indexer/opensearch-security/` directory on your Wazuh Indexer server.
|
|
|
|
3. Change the ownership of the `wazuh_authentik_meta.xml` file to the `wazuh-indexer` user using the following command:
|
|
|
|
```bash
|
|
chown wazuh-indexer:wazuh-indexer /etc/wazuh-indexer/opensearch-security/wazuh_authentik_meta.xml
|
|
```
|
|
|
|
4. Edit the `/etc/wazuh-indexer/opensearch-security/config.yml` on your Wazuh Indexer server.
|
|
|
|
Add a `saml_auth_domain` section after the `basic_internal_auth_domain` section. For example:
|
|
|
|
```yaml {7,10,13-30} showLineNumbers title="/etc/wazuh-indexer/opensearch-security/config.yml"
|
|
---
|
|
authc:
|
|
basic_internal_auth_domain:
|
|
description: "Authenticate SAML 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_file: "/etc/wazuh-indexer/opensearch-security/wazuh_authentik_meta.xml"
|
|
entity_id: "wazuh-saml"
|
|
sp:
|
|
entity_id: "wazuh-saml"
|
|
kibana_url: "https://wazuh-dashboard.company/"
|
|
roles_key: Roles
|
|
exchange_key: "<exchange key generated in step 1>"
|
|
authentication_backend:
|
|
type: noop
|
|
```
|
|
|
|
:::note
|
|
Ensure that you set the following parameters in the `basic_internal_auth_domain` section: `order: 0` and `challenge: false`
|
|
|
|
And the `metadata_file`, `kibana_url`, and `exchange_key` parameters in the `saml_auth_domain` section.
|
|
:::
|
|
|
|
5. Run the `securityadmin.sh` script to load the configuration changes made in the `/etc/wazuh-indexer/opensearch-security/config.yml` file, ensure that you update the `-h` flag to your Wazuh Indexer FQDN:
|
|
|
|
```bash
|
|
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 wazuh-indexer.company -nhnv
|
|
```
|
|
|
|
6. Edit the `/etc/wazuh-indexer/opensearch-security/roles_mapping.yml` file and include `wazuh_admin` as a `backend_role` in the appropriate section. The following example adds the role to the `all_access` section:
|
|
|
|
```yaml showLineNumbers title="/etc/wazuh-indexer/opensearch-security/roles_mapping.yml"
|
|
all_access:
|
|
reserved: true
|
|
hidden: false
|
|
backend_roles:
|
|
// highlight-next-line
|
|
- "wazuh-admin"
|
|
- "admin"
|
|
hosts: []
|
|
users: []
|
|
and_backend_roles: []
|
|
description: "Maps admin to all_access"
|
|
```
|
|
|
|
7. Run the `securityadmin.sh` script again but with the `-f` flag set to `/etc/wazuh-indexer/opensearch-security/roles_mapping.yml`, ensure that you update the `-h` flag to your Wazuh Indexer FQDN:
|
|
|
|
```bash
|
|
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 wazuh-indexer.company{" "} -nhnv
|
|
```
|
|
|
|
### Wazuh dashboard configuration
|
|
|
|
1. On the Wazuh Dashboard server, check the value of `run_as` in the `/usr/share/wazuh-dashboard/data/wazuh/config/wazuh.yml` configuration file:
|
|
|
|
```yaml showLineNumbers title="/usr/share/wazuh-dashboard/data/wazuh/config/wazuh.yml"
|
|
hosts:
|
|
- default:
|
|
url: https://127.0.0.1
|
|
port: 55000
|
|
username: wazuh-wui
|
|
password: "<WAZUH_WUI_PASSWORD>"
|
|
// highlight-next-line
|
|
run_as: false
|
|
```
|
|
|
|
The `run_as` parameter when set to true, enables the assignment of roles to users based on authorization context information. See the (Wazuh Authorization Context documentation)[https://documentation.wazuh.com/current/user-manual/api/rbac/auth-context.html] for more information.
|
|
|
|
If `run_as` is set to `false`, proceed to step 4. If `run_as` is set to `true`, proceed with the following steps to add a role mapping on the Wazuh dashboard.
|
|
|
|
2. On the Wazuh dashboard click the upper-left menu icon ☰ to open the menu, go to **Server management** -> **Security** -> **Roles mapping**
|
|
|
|
3. Click **Create Role mapping** and configure the following parameters:
|
|
|
|
- **Role Name**: set a name for the role mapping (e.g. authentik_admins)
|
|
- **Roles**: select a role (e.g.`administrator`)
|
|
- **Custom rules**: Click **Add new rule** and set:
|
|
- **User field**: `backend_roles`
|
|
- **Search operation**: `FIND`
|
|
- **Value**: `wazuh-admin`
|
|
|
|
Click **Save role mapping**
|
|
|
|
4. On the Wazuh Dashboard server, add these lines to the `/etc/wazuh-dashboard/opensearch_dashboards.yml` file:
|
|
|
|
```yaml showLineNumbers
|
|
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
|
|
```
|
|
|
|
5. Restart the Wazuh dashboard service using the following command:
|
|
|
|
```bash
|
|
sudo systemctl restart wazuh-dashboard
|
|
```
|
|
|
|
## Configuration verification
|
|
|
|
To confirm that authentik is properly configured with Wazuh, log out and log back in using an account that is a member of the appropriate authentik group (e.g. `wazuh-administrators`).
