Sourcefire 3D System Release Notes

Before You Begin: Important Update and Compatibility Notes

well as with any compatibility issues or required pre- or post-update configuration 

changes.

The update to Version 5.3 fails if your configuration includes a 

custom table populated with data from the Correlation Events table and the 

Applications table with Source IP selected as a common field. If your configuration 

includes a custom table of this type, delete the custom table and recreate it after 

completing the update to Version 5.3.

Sourcefire strongly recommends you perform the update in a 

maintenance window or at a time when the interruption will have the least impact 

on your deployment.

For more information, see the following sections:

Configuration and Event Backup Guidelines

Before you begin the update, Sourcefire strongly recommends that you delete or 

move any backup files that reside on your appliance, then back up current event 

and configuration data to an external location.
Use the Defense Center to back up event and configuration data for itself and the 

devices it manages. For more information on the backup and restore feature, see 

the Sourcefire 3D System User Guide.

The Defense Center purges backups from previous updates. To 

retain archived backups, store the backups externally.

Traffic Flow and Inspection During the Update

The update process reboots managed devices. Depending on how your devices 

are configured and deployed, the following capabilities are affected:

traffic inspection, including application awareness and control, URL filtering, 

Security Intelligence, intrusion detection and prevention, and connection 

logging 

traffic flow, including switching, routing, NAT, VPN, and related functionality
