Before deploying to a production environment, you should replace the demo security certificates and configuration YAML files with your own. With the tarball, you have direct access to the file system, but the Docker image requires modifying the Docker storage volumes to include the replacement files.
OPENSEARCH_HOSTS: '["https://opensearch-node1:9200","https://opensearch-node2:9200"]' # must be a string with no spaces when specified as an environment variable
Then make your changes to `opensearch.yml`. For a full list of settings, see [Security]({{site.url}}{{site.baseurl}}/security-plugin/configuration/index/). This example adds (extremely) verbose audit logging:
Use this same override process to specify new [authentication settings]({{site.url}}{{site.baseurl}}/security-plugin/configuration/configuration/) in `/usr/share/opensearch/plugins/opensearch-security/securityconfig/config.yml`, as well as new default [internal users, roles, mappings, action groups, and tenants]({{site.url}}{{site.baseurl}}/security-plugin/configuration/yaml/).
If you encounter any `File /usr/share/opensearch/config/opensearch.yml has insecure file permissions (should be 0600)` messages, you can use `chmod` to set file permissions before running `docker-compose up`. Docker Compose passes files to the container as-is.

Finally, you can reach OpenSearch Dashboards at http://localhost:5601, sign in, and use the **Security** panel to perform other management tasks.
To use your own certificates in your configuration, add all of the necessary certificates to the volumes section of the Docker Compose file:
```yml
volumes:
- ./root-ca.pem:/full/path/to/certificate.pem
- ./admin.pem:/full/path/to/certificate.pem
- ./admin-key.pem:/full/path/to/certificate.pem
#Add other certificates
```
After replacing the demo certificates with your own, you must also include a custom `opensearch.yml` in your setup, which you need to specify in the volumes section.
Remember that the certificates you specify in your Docker Compose file must be the same as the certificates listed in your custom `opensearch.yml` file. At a minimum, you should replace the root, admin, and node certificates with your own. For more information about adding and using certificates, see [Configure TLS certificates]({{site.url}}{{site.baseurl}}/security-plugin/configuration/tls).
