Integrate McAfee GTI file reputation with Forcepoint NGFW

Integrating Forcepoint NGFW with McAfee Global Threat Intelligence file reputation services allows access control based on the scan results.

Before you begin

Note: This feature requires a separate license.

Integrating McAfee GTI requires enabling McAfee GTI File Reputation and authorizing the use of the McAfee GTI service.

The McAfee GTI database contains classifications of files. When a file transfer matches a rule in the File Filtering Policy that applies McAfee GTI file reputation, the NGFW Engine sends a hash of the file to the McAfee GTI cloud. McAfee GTI file reputation compares the hash of the file against the McAfee GTI database.

Only a hash of the file is sent to the McAfee GTI cloud. No other data or telemetry information is sent to the McAfee GTI cloud.

    1. Select Menu > System Tools > Global System Properties.
    2. On the Global Options tab, select Enable McAfee Global Threat Intelligence (GTI) and Threat Intelligence (TIE) usage.

  • Click Export to export the Snort configuration file.

All NGFW Engines for which Snort inspection is enabled use the global Snort configuration by default.

Settings in the Snort configuration .zip file for an individual NGFW Engine are combined with the settings in the global Snort configuration .zip file. If any configuration files in a Snort configuration .zip file for an individual NGFW Engine have the same files name and paths as configuration files in the global Snort configuration .zip file, the overlapping files in the global Snort configuration .zip file are ignored.
