Updating Your Appliances

9. After the update finishes, clear your browser cache and force a reload of the 

browser. Otherwise, the user interface may exhibit unexpected behavior.

10. Log into the Defense Center.
11. Select Help > About and confirm that the software version is listed correctly: 

Version 5.2.0.6. Also note the versions of the rule update and VDB on the 

Defense Center; you will need this information later.

12. Verify that the appliances in your deployment are successfully communicating 

and that there are no issues reported by the health monitor.

13. If the rule update available on the Support Site is newer than the rules on your 

Defense Center, import the newer rules.
For information on rule updates, see the Sourcefire 3D System User Guide.

14. If the VDB available on the Support Site is newer than the VDB on your 

Defense Center, install the latest VDB.
Installing a VDB update with detection updates may cause a short pause in 

traffic flow and processing, and may also cause a few packets to pass 

uninspected. For more information, see the Sourcefire 3D System User 

Guide.

For the update to Version 5.2.0.6, Sourcefire recommends 

installing VDB build 156 or later.

15. Reapply device configurations to all managed devices.

To reactivate a grayed-out Apply button, edit any interface in the device 

configuration, then click Save without making changes.

16. Reapply access control policies to all managed devices.

Do not reapply intrusion policies individually; you must reapply 

all access control policies completely.

Applying an access control policy may cause a short pause in traffic flow and 

processing, and may also cause a few packets to pass uninspected. For more 

information, see the Sourcefire 3D System User Guide.

Updating Managed Devices

After you update your Defense Centers to Version 5.2.0.6, use them to update 

the devices they manage. 
Updating managed devices is a two-step process. First, download the update 

from the Support Site and upload it to the managing Defense Center. Next, install
