Version 5.3.0.2

Sourcefire 3D System Release Notes

39

Features Introduced in Previous Versions

AMP Cloud Connectivity

: Malware, URL Filtering

: Any except DC500

Prior to Version 5.3, to connect to the Sourcefire cloud you had to use TCP Port 

32137 and a direct connection from the Defense Center to the cloud.
Version 5.3 introduced proxy support for connecting to the Sourcefire cloud to do 

malware detection and dynamic analysis. Previously, you had to use TCP port 

32137, but now the default connection is made over TCP port 443 to allow more 

organizations to connect and use Sourcefire’s advanced malware intelligence. 

Use of port 32137 is still supported, but is no longer the default.
Note that if you are updating to Version 5.3 from a previous version of the 

Sourcefire 3D System, use of legacy port 32137 is enabled by default. If you want 

to connect via port 443 after updating, deselect the checkbox on the Cloud 

Services page (System > Local > Configuration > Cloud Services).

Host and Event Correlation IOC Style (Indications of Compromise)

: FireSIGHT + Protection or FireAMP subscription

: Feature dependent

: Feature dependent

Host and event correlation introduced the ability to pinpoint the hosts on your 

network that may have been compromised by an attack. Host and event 

correlation aggregates data from intrusion events, connection events, Security 

Intelligence events, and FireAMP events to help you quickly diagnose and contain 

security breaches on your network.
This feature introduced Sourcefire-provided Indications of Compromise (IOC) 

rules that allow you to control whether the system generates IOC events for 

particular types of compromise and correlates those events with the host 

involved. At the time of event generation, the system sets an IOC tag on the 

affected host impacted by that IOC event. Hosts that have the most IOC events 

associated with them from unique detection sources are those that are most 

likely compromised. Once you have resolved the breach, the IOC tags are 

removed. IOC events and host tags are viewable in the host profile, network map, 

Context Explorer, dashboard, and event viewers.

Enhanced Security Intelligence Event Storage and Views

: Protection

: Series 3, Virtual, X-Series

: Any except DC500

If your system is configured to blacklist traffic or monitor blacklisted traffic based 

on Security Intelligence data, you can now view Security Intelligence events in 

dashboards and in the Context Explorer. Security Intelligence events, although 

similar to connection events, are stored and pruned separately and have their own 

event view, workflows, and Custom Analysis dashboard widget presets.
