Sourcefire 3D System Release Notes

Features Introduced in Previous Versions

detection list in combination with the clean list, which lets you mark specific files 

as clean.
Together, the custom file detection list and clean list help you customize your 

malware protection approach to your specific environment. The custom file 

detection list and clean list are included by default in every file policy, and you can 

opt not to use either or both lists on a per-policy basis.

Spero Engine

: Malware

: Series 3, Virtual, X-Series

: Any except DC500

The Spero engine feature provided another cloud-based method for detecting 

suspicious and potentially new malware in executable files using big data. Spero 

creates a signature of an executable file based on the structural information of 

that file, the dynamic-link libraries (DLL) that are referenced, and the metadata 

from the Portable Executable (PE) header. This feature print then runs through the 

machine learned data trees for analysis and determines whether the file contains 

malware. The Spero analysis result is considered jointly with the file disposition to 

generate a final disposition for the executable file.

SMB File Detection

: Protection

: Feature dependent

: Feature dependent

As of Version 5.3, you can now detect, inspect, and block files transferred in 

NetBIOS-ssn traffic, including files transferred over Server Message Block (SMB).

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).
