# Enabling Security on the Management Station and Login Node
Omnia uses FreeIPA to enable security features like authorisation and access control.
## Enabling Authentication on the Management Station:
Set the parameter 'enable_security_support' to true in `base_vars.yml`
## Prerequisites Before Enabling Security:
* Enter the relevant values in `security_vars.yml`:
| Parameter Name | Default Value | Additional Information |
|------------------------|-----------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| domain_name | omnia.test | The domain name should not contain an underscore ( _ ) |
| realm_name | OMNIA.TEST | The realm name should follow the following rules per https://www.freeipa.org/page/Deployment_Recommendations
* The realm name must not conflict with any other existing Kerberos realm name (e.g. name used by Active Directory).
* The realm name should be upper-case (EXAMPLE.COM) version of primary DNS domain name (example.com). |
| max_failures | 3 | Failures allowed before lockout.
This value cannot currently be changed. |
| failure_reset_interval | 60 | Period (in seconds) after which the number of failed login attempts is reset
Accepted Values: 30-60 |
| lockout_duration | 10 | Period (in seconds) for which users are locked out.
Accepted Values: 5-10 |
| session_timeout | 180 | Period (in seconds) after which idle users get logged out automatically
Accepted Values: 30-90 |
| alert_email_address | | Email address used for sending alerts in case of authentication failure
If this variable is left blank, authentication failure alerts will be disabled. |
| allow_deny | Allow | This variable sets whether the user list is Allowed or Denied.
Accepted Values: Allow, Deny |
| user | | Array of users that are allowed or denied based on the `allow_deny` value. Multiple users must be separated by a space. |
* Enter the relevant values in `login_vars.yml`:
| Parameter Name | Default Value | Additional Information |
|----------------------------|---------------|--------------------------------------------------------------------------------------------------|
| ms_directory_manager_password | | Password of the Directory Manager with full access to the directory for system management tasks. |

## Log Aggregation via Grafana
[Loki](https://grafana.com/docs/loki/latest/fundamentals/overview/) is a datastore used to efficiently hold log data for security purposes. Using the `promtail` agent, logs are collated and streamed via a HTTP API.
>> __Note:__ When `control_plane.yml` is run, Loki is automatically set up as a data source on the Grafana UI.
### Querying Loki
Loki uses basic regex based syntax to filter for specific jobs, dates or timestamps.
* Select the Explore  tab to select control-plane-loki from the drop down.
* Using [LogQL queries](https://grafana.com/docs/loki/latest/logql/log_queries/), all logs in `/var/log` can be accessed using filters (Eg: `{job=”Omnia”}` )
## Viewing Logs on the Dashboard
All log files can be viewed via the Dashboard tab (). The Default Dashboard displays `omnia.log` and `syslog`. Custom dashboards can be created per user requirements.
Below is a list of all logs available to Loki and can be accessed on the dashboard:
