Before running `securityadmin.sh` to load the settings into the `.opendistro_security` index, configure the YAML files in `plugins/opensearch-security/securityconfig`. You might want to back up these files so that you can reuse them on other clusters.
The best use of these YAML files is to configure [reserved and hidden resources]({{site.url}}{{site.baseurl}}/security-plugin/access-control/api#reserved-and-hidden-resources), such as the `admin` and `kibanaserver` users. You might find it easier to create other users, roles, mappings, action groups, and tenants using OpenSearch Dashboards or the REST API.
The file format requires a hashed password. To generate one, run `plugins/opensearch-security/tools/hash.sh -p <new-password>`. If you decide to keep any of the demo users, *change their passwords* and re-run [securityadmin.sh]({{site.url}}{{site.baseurl}}/security-plugin/configuration/security-admin/) to apply the new passwords.
In addition to many OpenSearch settings, this file contains paths to TLS certificates and their attributes, such as distinguished names and trusted certificate authorities.
If you want to run your users' passwords against some validation, specify a regular expression (regex) in this file. You can also include an error message that loads when passwords don't pass validation. The following example demonstrates how to include a regex so OpenSearch requires new passwords to be a minimum of eight characters with at least one uppercase, one lowercase, one digit, and one special character.
plugins.security.restapi.password_validation_error_message: "Password must be minimum 8 characters long and must contain at least one uppercase letter, one lowercase letter, one digit, and one special character."
You can use `whitelist.yml` to allow list any endpoints and HTTP requests. If enabled, all users except the SuperAdmin are allowed access to only the specified endpoints and HTTP requests, and all other HTTP requests associated with the endpoint are denied. For example, if GET `_cluster/settings` is allow listed, users cannot submit PUT requests to `_cluster/settings` to update cluster settings.
Note that while you can configure access to endpoints this way, for most cases, it is still best to configure permissions using the security plugin's users and roles, which have more granular settings.
You can also allow list custom indices. `whitelist.yml` doesn't support wildcards, so you must manually specify all of the indices you want to allow list.
This file contains any initial roles that you want to add to the security plugin. Aside from some metadata, the default file is empty, because the security plugin has a number of static roles that it adds automatically.

## action_groups.yml
This file contains any initial action groups that you want to add to the security plugin.
Aside from some metadata, the default file is empty, because the security plugin has a number of static action groups that it adds automatically. These static action groups cover a wide variety of use cases and are a great way to get started with the plugin.
You can use this file to specify and add any number of OpenSearch Dashboards tenants to your OpenSearch cluster. For more information about tenants, see [OpenSearch Dashboards multi-tenancy]({{site.url}}{{site.baseurl}}/security-plugin/access-control/multi-tenancy).
Like all of the other YAML files, we recommend you use `tenants.yml` to add any tenants you must have in your cluster, and then use OpenSearch Dashboards or the [REST API]({{site.url}}{{site.baseurl}}/security-plugin/access-control/api/#tenants) if you need to further configure or create any other tenants.
`nodes_dn.yml` lets you allow list certificates' [distinguished names (DNs)]({{site.url}}{{site.baseurl}}/security-plugin/configuration/generate-certificates/#add-distinguished-names-to-opensearchyml) to enable communication between any number of nodes and/or clusters. For example, a node that allow lists the DN `CN=node1.example.com` accepts communication from any other node or certificate that uses that DN.
The DNs get indexed into a [system index]({{site.url}}{{site.baseurl}}/security-plugin/configuration/system-indices) that only a super admin or an admin with a Transport Layer Security (TLS) certificate can access. If you want to programmatically allow list DNs, use the [REST API]({{site.url}}{{site.baseurl}}/security-plugin/access-control/api/#distinguished-names).
