Overview of Geographic Edition and Security

Geographic Edition software is a layered extension of the Oracle Solaris Cluster software. Data replication software enables applications that are running on a Geographic Edition cluster to tolerate disasters by migrating services to a geographically separated secondary cluster. A disaster such as an earthquake, fire, or storm might disable the cluster at the primary site.

If a disaster occurs, the Geographic Edition cluster can continue to provide services by using the following levels of redundancy:

• A secondary cluster

• Duplicated application configuration on the secondary cluster

• Replicated data on the secondary cluster

The Geographic Edition software provides a suite of tools to manage and configure geographically separated clusters with a migration of services between sites. The Geographic Edition software can manage availability across multiple physical locations through robust security, application service migration, and data replication to tolerate disaster across an enterprise system.

On Geographic Edition 4.1, the clusters can be global clusters, zone clusters, or a combination of both.

General Security Principles

The following principles are fundamental to using the Geographic Edition application securely.

• Keep software up to date

• Restrict network access to critical services

• Follow the principle of least privilege

• Monitor system activity

• Keep up to date on the latest Oracle security information
