Enabling Security on the Management Station and Login Node

Omnia uses FreeIPA to enable security features like authorisation and access control.

Set the parameter 'enable_security_support' to true in base_vars.yml

Prerequisites Before Enabling FreeIPA:

• Enter the relevant values in security_vars.yml:

Parameter Name	Default Value	Additional Information

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).

• Enter the relevant values in login_vars.yml:

Parameter Name	Default Value	Additional Information
directory_manager_password		Password of the Directory Manager with full access to the directory for system management tasks.
ipa_admin_password		"admin" user password for the IPA server

Log Aggregation via Grafana

Loki 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, 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:
