Managing security in a cluster

The Cluster service relies on Windows Server 2003 family security at all levels for securing communication between nodes, and controlling authentication and access, including client access to the cluster and cluster resources. You can use Cluster Administrator to specify which users or groups can:

• Administer the cluster.
• Access files or folders on File Share resources.

For more information on setting server cluster administration permissions, see To give a user permissions to administer a cluster.

For information on how to change the account or the password for the Cluster service, see To change the account under which the Cluster service runs and To change the Cluster service account password.

This section covers common security tasks:

• Limiting client access to cluster resources
• Securing shared data in a cluster
• Domain accounts and the Cluster service
• Disk resource security
