Security Considerations
-----------------------

This section describes the security limitations you should keep in mind when deploying a Virtuozzo Storage cluster.

**Traffic sniffing**

Virtuozzo Storage does not protect you from traffic sniffing. Anyone who has access to your network can capture and analyze the data being sent and received through your network.

To learn how to keep your data secure, see :ref:`Securing Server Communication in Clusters`.

**Absence of users and groups**

Virtuozzo Storage does not use the concept of users and groups, providing specific users and groups with access to specific parts of a cluster. Anyone authorized to access a cluster can access all its data.

**Non-encrypted data on disks**

Virtuozzo Storage does not encrypt data stored in a cluster. Attackers can immediately see the data once they gain access to a physical disk drive.
