FireSIGHT System Release Notes
Version 5.3.1
  Installing the Update
The update process begins. You can begin monitoring the update's progress in the task queue (
System > 
Monitoring > Task Status
). However, after the Defense Center completes its necessary pre-update checks, 
you are logged out. When you log back in, the Upgrade Status page appears. The Upgrade Status page 
displays a progress bar and provides details about the script currently running.
If the update fails for any reason, the page displays an error message indicating the time and date of the 
failure, which script was running when the update failed, and instructions on how to contact Support. Do 
not restart the update.
Caution
If you encounter any other issue with the update (for example, if a manual refresh of the Update Status 
page shows no progress for several minutes), do not restart the update. Instead, contact Support.
When the update completes, the Defense Center displays a success message and reboots.
Step 9
After the update finishes, clear your browser cache and force a reload of the browser. Otherwise, the user 
interface may exhibit unexpected behavior.
Step 10
Log into the Defense Center.
Step 11
Review and accept the End User License Agreement (EULA). Note that you are logged out of the 
appliance if you do not accept the EULA.
Step 12
Select 
Help > About
 and confirm that the software version is listed correctly: Version 5.3.1. Also note the 
versions of the rule update and VDB on the Defense Center; you will need this information later.
Step 13
Verify that the appliances in your deployment are successfully communicating and that there are no 
issues reported by the health monitor.
Step 14
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 FireSIGHT System User Guide.
Step 15
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 causes a short pause in traffic flow and processing, and may also cause a few 
packets to pass uninspected. For more information, see the FireSIGHT System User Guide.
Step 16
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.
Step 17
Reapply access control policies to all managed devices.
Caution
Do not reapply your 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 FireSIGHT System User Guide.
Step 18
If a patch for Version 5.3.1 is available on the Support site, apply the latest patch as described in the 
FireSIGHT System Release Notes for that version. You must update to the latest patch to take advantage 
of the latest enhancements and security fixes.
